When is the best time to visit Costa Rica?
The best time to visit Costa Rica largely depends on your priorities and what you want to experience. Generally speaking, Costa Rica has two distinct seasons: the dry season (December to April) and the green season (May to November).
The dry season, especially from December to February, is considered the peak tourist season in Costa Rica. During these months, you'll enjoy sunny days with minimal rainfall, making it ideal for beach activities, hiking, and wildlife spotting. However, this is also when the country sees the highest number of tourists and the highest prices.
The green season (also called the rainy season) shouldn't be dismissed, though. From May to November, the landscapes become incredibly lush and vibrant. While afternoon showers are common, mornings are typically sunny and clear. This season offers fewer crowds, lower prices, and the opportunity to see Costa Rica at its most verdant. September and October tend to see the heaviest rainfall, particularly on the Pacific coast.
For those seeking a balance between good weather and fewer crowds, the shoulder months of May, June, and November can offer the best of both worlds. These transitional periods often feature pleasant weather conditions with occasional short rain showers and lower tourist numbers than the peak dry season.
What is Costa Rica's dry season like?
Costa Rica's dry season, spanning from December to April, is characterized by sunny, hot days with minimal rainfall, especially in popular tourist regions like Guanacaste and the Central Pacific coast. This makes it the most popular time for travelers, particularly those escaping winter in North America and Europe.
During the dry season, the weather is consistently pleasant with temperatures ranging from 70°F to 90°F (21°C to 32°C), depending on the elevation and region. The lack of rain means that trails are easier to navigate, roads are more accessible, and outdoor activities can be planned with greater certainty. It's an excellent time for beach activities, surfing (particularly on the Pacific coast), and exploring the country's various national parks.
The landscape during this season appears more golden and less lush than during the green season. Rivers may have lower water levels, which can affect activities like white-water rafting in some regions. Wildlife viewing remains excellent, especially in protected areas like Manuel Antonio National Park or Corcovado National Park.
It's worth noting that the dry season coincides with the high tourist season, which means more crowded attractions, higher accommodation prices, and the need to book tours and hotels well in advance. If you're planning to visit during this time, particularly around Christmas, New Year, or Easter, securing your arrangements early is essential.

When is Costa Rica's green season, and what can I expect?
Costa Rica's green season, also known as the rainy season, runs from May through November and transforms the country into a lush paradise of vibrant vegetation and flowing waterfalls. Despite its reputation, the green season doesn't mean constant downpours; instead, the typical pattern consists of sunny mornings followed by afternoon showers, with the rain often clearing by evening.
During this season, Costa Rica truly lives up to its name, which translates to "Rich Coast." The rainfall nourishes the landscapes, creating spectacular scenery with forests at their most verdant and waterfalls at their most powerful. Rivers swell, making it an exciting time for white-water rafting enthusiasts. The green season also brings cooler temperatures, especially in the highlands, providing relief from the intense heat of the dry months.
Wildlife viewing takes on a different dimension during the green season. Many animals become more active, and it's the season when sea turtles come ashore to nest at various beaches along both coasts. The Arenal region often has clearer views of the volcano in the mornings during these months, as clouds tend to gather later in the day.
One of the greatest advantages of traveling during the green season is the significant reduction in tourist numbers. You'll find more solitude on the beaches, easier access to popular attractions, and more authentic interactions with locals. Additionally, many hotels and tour operators offer substantial discounts, sometimes up to 30% off high-season rates.
It's important to note that rainfall patterns vary considerably by region. The Caribbean coast, for instance, often experiences its driest period in September and October when the Pacific side sees its heaviest rainfall. This regional variation allows for strategic planning to enjoy drier conditions even during the country's official rainy season.
Which months are best for avoiding crowds in Costa Rica?
If you're looking to experience Costa Rica without the hustle and bustle of peak tourist season, planning your visit during the country's less crowded months can significantly enhance your experience. The months of May, June, September, October, and November generally offer the perfect balance of decent weather conditions and substantially fewer tourists.
May and June represent an excellent sweet spot in the Costa Rican tourism calendar. These early green season months see only moderate rainfall, typically in the form of afternoon showers, while the landscapes begin to transform into their lush, vibrant state. Tourist numbers drop dramatically after Easter and the spring break period, meaning you'll have more space to enjoy popular attractions like Manuel Antonio National Park or the beaches of Guanacaste.
September and October are the heart of the rainy season and consequently see the fewest international visitors, particularly on the Pacific coast where rainfall is heaviest during these months. However, this is actually the best time to visit the Caribbean coast, which experiences its driest, sunniest period during these months – a fact that many travelers overlook. The beach towns of Puerto Viejo and Cahuita are particularly pleasant during this "mini summer."
November represents another excellent opportunity as the rains begin to subside on the Pacific coast, but the high season crowds haven't yet arrived. The landscape remains lush and green, wildlife is abundant, and accommodation prices haven't yet reached their peak season heights.
During these less crowded months, you'll not only enjoy more personal space at attractions and on beaches, but you'll also benefit from more attentive service, greater flexibility with tour bookings, and a more authentic experience of local life. Many travelers report that their most memorable experiences in Costa Rica came during these "shoulder" and low season months when they could connect more deeply with the country's natural beauty and cultural heritage without the distractions of crowds.

What are the best regions to visit during Costa Rica's rainy season?
While Costa Rica's rainy season (May to November) affects the entire country, rainfall patterns vary significantly by region, creating opportunities for travelers to enjoy relatively dry conditions even during the officially wet months. Strategic regional planning can help you maximize sunny days during your green season visit.
The Caribbean coast, particularly around Puerto Viejo and Cahuita, experiences its driest, most pleasant weather during September and October – precisely when the Pacific coast sees its heaviest rainfall. This "Caribbean summer" is one of Costa Rica's best-kept secrets, offering visitors beautiful beach days with reduced rainfall and incredible opportunities to observe nesting sea turtles at Tortuguero National Park.
The Northern Plains and Arenal Volcano area typically receive less rainfall than the Southern Pacific regions during the green season. While afternoon showers are common, mornings usually remain clear enough for activities like hiking, zipline tours, and hot spring visits. The increased water flow during this season makes the La Fortuna Waterfall particularly spectacular.
Guanacaste, in the northwestern part of the country, sits in a rain shadow and receives significantly less precipitation than other Pacific regions even during the rainy months. This area, known as Costa Rica's "Gold Coast," maintains relatively dry conditions through much of the green season, especially in May, June, and July when afternoon showers are brief and refreshing rather than persistent.
The Central Valley, including San José and surrounding areas, experiences moderate rainfall during the green season, with many days following the pattern of sunny mornings and afternoon showers. This makes it possible to plan morning activities in destinations like Poás Volcano National Park or the charming town of Zarcero with a good chance of clear views and dry conditions.
If you're particularly concerned about rain affecting your travel plans, consider dividing your time between different regions to maximize good weather opportunities. A well-planned itinerary might combine the Caribbean coast in September/October with time in Guanacaste or the Central Valley, allowing you to follow the most favorable weather patterns while experiencing diverse aspects of Costa Rica's natural beauty.
When is the best time to visit Costa Rica for wildlife viewing?
Costa Rica's extraordinary biodiversity offers wildlife viewing opportunities year-round, but certain seasons may enhance your chances of witnessing specific animal behaviors and species. Your wildlife viewing priorities should influence your travel timing decisions.
The dry season (December to April) generally provides excellent overall wildlife viewing conditions. With less foliage and animals congregating around remaining water sources, spotting creatures like monkeys, sloths, and tropical birds becomes somewhat easier. National parks like Manuel Antonio and Corcovado are particularly rewarding during these months, as animals are more visible on clear, sunny days.
For turtle enthusiasts, timing is crucial. The Pacific coast, particularly at Ostional and Nancite beaches, hosts arribadas (mass nesting events of Olive Ridley turtles) primarily between August and December. On the Caribbean coast, green sea turtles nest at Tortuguero National Park from July to October. Leatherback turtles can be observed on the Caribbean coast from March to May and on the Pacific from September to March.
Bird watchers should consider that while resident species can be seen year-round, the dry season (December to April) coincides with the migration of many North American species to Costa Rica. However, the onset of the rainy season triggers breeding behaviors in many bird species, making May and June excellent for observing courtship displays and nesting activities.
The green season brings its own wildlife viewing advantages. The increased moisture awakens many amphibians, making it the best time to spot colorful frogs, including the iconic red-eyed tree frog. Whale watching is particularly rewarding from July to October along the Pacific coast, when humpback whales from the southern hemisphere migrate to Costa Rican waters to breed and calve.
For those interested in marine life, visibility for snorkeling and diving is generally best during the dry months on the Pacific coast. However, the Caribbean coast often offers better underwater visibility during September and October, coinciding with its mini dry season.
Regardless of when you visit, early morning and late afternoon remain the optimal times for wildlife viewing, as many animals are most active during these cooler hours. Hiring a knowledgeable local guide will significantly increase your chances of spotting elusive wildlife throughout the year.

What is the weather like in Costa Rica during different seasons?
Costa Rica's climate varies significantly by region and elevation, creating diverse microclimates despite the country's small size. Understanding these regional weather patterns is essential for planning your visit effectively.
In the Central Valley, including San José, the climate remains pleasantly moderate year-round, with temperatures typically ranging from 65°F to 80°F (18°C to 27°C). During the dry season (December to April), expect sunny days with minimal cloud cover. The rainy season brings afternoon showers, with September and October seeing the heaviest rainfall, though mornings generally remain clear.
The Pacific coast experiences a more pronounced dry/wet season distinction. The North Pacific (Guanacaste) is the driest region, with temperatures often reaching 90°F to 95°F (32°C to 35°C) during the dry months. Even during the rainy season, this region receives less precipitation than other parts of the country. The Central and South Pacific areas become increasingly wetter as you move south, with the Osa Peninsula receiving up to 300 inches of annual rainfall.
The Caribbean coast follows a different pattern entirely. This region tends to be humid year-round, with rainfall distributed more evenly throughout the year. Its driest months typically occur in February, March, September, and October – creating a "mini summer" in September and October when much of the rest of the country experiences peak rainfall.
The Northern Plains and mountainous regions present yet another climate profile. Areas like Monteverde and Arenal experience cooler temperatures due to their elevation, with averages ranging from 60°F to 75°F (16°C to 24°C). These regions receive significant rainfall even during the "dry" season, though it's typically less than during the green months.
It's worth noting that climate change has begun to affect Costa Rica's traditional weather patterns. In recent years, the dry season has sometimes extended longer than usual, while rainfall intensity has increased during the wet months. This variability makes it even more important to check current conditions and forecasts when planning your trip.
Regardless of when you visit, packing layers is advisable, especially if you'll be traveling between different regions or elevations. Even during the hottest months, highland areas can become quite cool in the evenings, while coastal regions remain warm day and night.
When is the most affordable time to visit Costa Rica?
Traveling to Costa Rica during its green season (May to November) offers significant cost savings across accommodations, tours, and activities compared to the peak dry season. This price difference can make a substantial impact on your overall budget and potentially allow for a longer or more luxurious experience.
During the green season, particularly in September and October when rainfall is highest, many hotels and resorts offer discounts of 20-40% compared to high season rates. Boutique properties and eco-lodges that might be out of reach price-wise during the dry months become more accessible during this period. Some establishments also provide additional value through free night promotions (such as "stay 4 nights, pay for 3") or complementary upgrades when occupancy is lower.
Tour operators and activity providers similarly adjust their pricing during the green season. White-water rafting, canopy tours, guided hikes, and wildlife excursions often come with reduced rates. Beyond the direct discounts, the decreased demand means you'll frequently enjoy more personalized experiences with smaller group sizes or even private tours for the price of group activities.
Transportation costs within Costa Rica also tend to be lower during the green season. Car rental companies offer better rates and are more willing to negotiate on upgrades or insurance packages. Domestic flights, particularly to popular destinations like Quepos (Manuel Antonio) or Tamarindo, frequently run promotions during these months.
The shoulder months of May, June, and November represent particularly good value. During these transitional periods, you'll experience relatively good weather conditions with moderate rainfall, while still benefiting from reduced green season pricing before rates increase for the high season.
It's worth noting that while Christmas, New Year, and Easter weeks represent the absolute peak in terms of pricing (with some accommodations charging premium rates up to double their standard high-season prices), July and August often see a "mini high season" due to European and North American summer holidays. During these summer months, prices may increase somewhat from the early green season rates, though they typically remain below dry season levels.
For budget-conscious travelers seeking the absolute best value, planning a trip for late September or early October and focusing on the Caribbean coast (which experiences its driest period during these months) offers an optimal combination of good weather and maximum affordability.

What are the best activities to do in Costa Rica by season?
Costa Rica offers an incredible variety of activities year-round, but certain seasons enhance specific experiences. Planning your activities according to the seasons will help you make the most of your visit to this diverse destination.
During the dry season (December to April), beach activities reach their peak potential. The Pacific coast offers excellent conditions for swimming, snorkeling, and sunbathing, with reliable sunshine and calm waters in protected bays. This is also prime time for sportfishing, particularly for sailfish and marlin off the Pacific coast. Surfers, however, should note that the largest swells on the Pacific side typically occur during the green season.
Hiking and land-based exploration are generally more comfortable during the dry months. Popular destinations like Corcovado National Park are more accessible, with trails that aren't muddy or slippery. The clear skies also make this the optimal season for zip-lining and canopy tours in destinations like Monteverde, offering unobstructed views of the spectacular landscapes below.
The green season (May to November) brings its own set of ideal activities. White-water rafting reaches its peak excitement level as rivers swell with rainwater, creating more challenging rapids and access to sections that might be too low during the dry months. The Pacuare and Sarapiquí rivers offer some of the best experiences during this period.
Wildlife viewing takes on different characteristics during the green season. It's the prime time to witness sea turtle nesting, particularly at Tortuguero National Park (July to October) and Ostional Wildlife Refuge (rainy season arribadas). Whale watching along the Pacific coast is best from July to October when humpback whales migrate from the southern hemisphere.
The green season also transforms Costa Rica's waterfalls, making them particularly spectacular. La Fortuna Waterfall near Arenal and the Nauyaca Waterfalls in the Southern Zone become powerful, impressive displays during these months, offering remarkable photography opportunities and swimming experiences in their natural pools.
For those interested in cultural experiences, many of Costa Rica's most vibrant festivals occur during specific times of the year. The Palmares Festival in January, the Diablitos Festival in Boruca during December/January, and Independence Day celebrations in September provide authentic cultural immersion opportunities.
Coffee enthusiasts should consider visiting between November and February, which coincides with the coffee harvest season. Many plantations offer special harvest tours during this period, allowing visitors to participate in the picking process and learn about production firsthand.
Regardless of the season, certain activities remain consistently excellent year-round, including hot springs visits in the Arenal region, chocolate and coffee tours, and wildlife viewing in protected reserves where experienced guides can help spot animals even in challenging conditions.
What should I pack for Costa Rica during different seasons?
Packing appropriately for Costa Rica's varied microclimates and seasonal conditions ensures you'll be comfortable throughout your trip. A well-prepared traveler adjusts their packing list based on both the season and the specific regions they plan to visit.
For the dry season (December to April), lightweight, breathable clothing is essential for coastal and lowland areas where temperatures can exceed 90°F (32°C). Pack plenty of short-sleeved shirts, shorts, lightweight pants, sundresses, and breathable underwear made from natural fibers or quick-dry materials. Even during the dry season, you should include a light rain jacket or poncho, as occasional showers can occur, particularly in mountainous regions.
Sun protection becomes especially important during the dry months when UV exposure is intense. Pack a wide-brimmed hat, high-quality sunglasses with UV protection, and reef-safe sunscreen with SPF 30 or higher. Consider UPF-rated clothing for additional protection during extended outdoor activities.
For the green season (May to November), waterproof gear becomes more critical. A reliable, breathable rain jacket is non-negotiable, and quick-dry clothing that won't stay wet for long periods is ideal. Some travelers find lightweight water-resistant pants more practical than shorts during this season, particularly for hiking or activities in forested areas.
Footwear requirements remain consistent year-round but take on added importance during the rainy months. Waterproof hiking boots or trail shoes with good traction are essential if you plan to explore natural areas, while water shoes are useful for rocky beaches and water activities. Always pack a pair of comfortable sandals for casual wear around towns and resorts.
If your itinerary includes higher elevation destinations like Monteverde, San Gerardo de Dota, or parts of the Central Valley, pack layers regardless of the season. Temperatures in these regions can drop into the 50s°F (10-15°C) at night, making a light fleece jacket, long pants, and even a warm hat welcome additions.
Tech gear and accessories require special consideration in Costa Rica's climate. A waterproof case or dry bag for your phone, camera, and other electronics is advisable year-round but essential during the green season. Consider bringing a portable clothesline for drying wet items in your accommodation, particularly useful during the rainy months.
Additional items to consider include:
- Insect repellent with DEET or picaridin
- Anti-itch cream for bug bites
- A small first aid kit
- A reusable water bottle
- A headlamp or flashlight (power outages are more common during the rainy season)
- Binoculars for wildlife viewing
- A lightweight daypack with rain cover
Remember that most items can be purchased in Costa Rica if forgotten, particularly in tourist areas and larger towns, though specialty items may be more expensive or limited in selection compared to North America or Europe.
Additional protection from the sun can come in handy, especially for little children.
Costa Rica offers remarkable experiences year-round, with each season presenting its own advantages. The dry season (December to April) provides reliable sunshine and easier access to most attractions but comes with higher prices and crowds. The green season (May to November) showcases the country at its most lush and vibrant, with fewer tourists and better values, though afternoon rainfall should be expected.
Regional variations create opportunities throughout the year, with the Caribbean coast offering a sunny reprieve in September and October when the Pacific experiences its heaviest rainfall. Wildlife enthusiasts will find different viewing opportunities across the seasons, from whale migrations to turtle nesting events.
Ultimately, the best time to visit Costa Rica depends on your priorities, whether they're specific activities, budget considerations, or weather preferences. By planning strategically around these factors, you can experience the rich biodiversity, stunning landscapes, and warm culture that make Costa Rica such a beloved destination.
