Best Time to Visit Costa Rica: Month-by-Month Guide (2026)

The best time to visit Costa Rica is from mid-December to April, the country's dry season, when the Pacific coast has lovely sunny days, warm temperatures running 75 - 90°F, and hardly any rainfall. Just right for beaches, rainforest hikes, and spotting wildlife. The green season (May - November) is characterized by lower prices, fewer crowds, beautiful nature, and the most active times of wildlife, including the sea turtles laying their eggs and humpback whales.

Which month is best really depends on what your priorities are. In this guide, we will discuss Costa Rica on a month by month and region by region basis to help you find the time that fits you best!

Costa Rica features 3 travel seasons, with weather, crowd, and cost factor changes characterizing each one. The dry season (mid-December until April) has the sunniest weather but at the same time, the prices are at a peak. The shoulder months (May, June, and November) provide the best overall value with warm mornings, occasional afternoon showers, and fewer tourists. The green season (July - October) brings the heaviest rain, however it is also the time when the prices are at their lowest and the wildlife is at its peak, perfect for nature and wildlife experiences in Costa Rica.

The dry season is a perfect time to visit Costa Rica since the sun almost always shines across the Pacific coast and Central Valley, making it especially ideal for honeymoon travel in Costa Rica. The average highs are between 75 - 90°F (24 - 32°C), and the lows are between 59 - 63°F (15 - 17°C). The Pacific side in January and February has virtually no rain at all. During March and April, the temperatures rise and the Guanacaste turns brown, but cloud forests will stay cooler. The trade-offs are the higher prices, busier parks, and rooms often booked 3+ months ahead.

Green season results in daily afternoon downpours, however the mornings are usually clear, which is why it is considered the best period to travel to Costa Rica. May, June and November are the best months with beautiful nature and not too much rain. Rain is even lesser in July and early August due to the "veranillo", a mini-drought of 3-4 weeks occurring mid-season. September and October are rainy months mostly in the Pacific side while Osa is usually inaccessible but at the same time, the Caribbean coast is at its driest. Temperatures remain fairly warm throughout the year.

In Costa Rica there are more than 20 microclimates in an area less than the size of West Virginia, so the ideal time to visit Costa Rica varies a lot by location. The dry Pacific northwest, humid Caribbean coast, the cloud forests of Monteverde and the spring-like Central Valley are so unique that each has its own calendar. Going to Guanacaste in February almost guarantees no rain, however, the same week in Tortuguero will normally have showers. The regional breakdown further down the guide will explain each zone in detail.

Changes in weather, wildlife, and tourism in Costa Rica throughout the year are quite significant, so the best time for you to visit Costa Rica will greatly depend on your availability. The below section provides a month-by-month guide of weather, crowds, prices, and top highlights so that you can align your trip with the best things to do in Costa Rica at the right time.

January is the height of the dry season, with clear skies all over and humpback whales along the Pacific coast. Quetzal breeding happens during this time in Monteverde and San Gerardo de Dota, so it`s a great month for bird watchers. The first week is crowded and expensive due to the New Year's rush but from January 5 to the end of the month prices fall and conditions are near perfect for about four weeks. Suitable for: newcomers who want sun and beach weather.

February falls right in the middle of the dry season and it is the hottest, driest month along the Pacific coast, with almost no rainfall in Guanacaste. Besides this, February is the best time of year to see the resplendent quetzal in Monteverde and San Gerardo de Dota, and humpback whales are still present offshore. National parks are still crowded and expensive during this time. Best for: people who want to mix wildlife watching with beach time and serious bird watchers.

March wraps up the dry season. It's hot, dry and dusty, with some rivers inland running low. Leatherback turtles are nesting on the Pacific coast, and it`s one of the best months for surfing due to consistent swells. The crowds and price spikes of Semana Santa (Holy Week) really hit. If Easter is in March you need to book well in advance. Best for: surfers, wildlife lovers, and active travelers who can handle heat.

The last month of the dry season, April, is also a transition month when the rainy season slowly makes its way in. Holy Week (Semana Santa) coinciding with late March or early April is the week with the highest domestic travel in the country, thus, it is highly recommended to make reservations several months in advance. The quetzal nesting is still very strong and the trails in the cloud forest are mostly dry and clear for hiking.

The green season starts in May and there is a pretty big reduction in both crowds and prices. Usually, the rain doesn't last very long and showers come in the afternoon leaving mornings nice and sunny. This is the best time for sightseeing and sunbathing. Olive ridley and leatherback turtles start coming to shore to nest, while the countryside transforms into a gorgeous green landscape. Hotels frequently provide 20-30% off discounts.

Although June is the month when rainfall gets more constant, it also makes Costa Rica colorful and lush. The number of tourists, especially those planning family travel in Costa Rica, starts to increase gradually from mid-June, so there will be a slight increase in crowds at popular places like Manuel Antonio. The Pacific waves are getting bigger for surfers, and green turtles are starting to come ashore for nesting on the northern Caribbean coast at Tortuguero. Ideal for: families, surfers and waterfalls.

July lies in the middle of the green season but brings "veranillo", a 3 - 4 week mini-dry window, especially on the northern Pacific coast, where the rainfall drops significantly. Green turtle nesting reaches its maximum at Tortuguero National Park, one of the most important nesting sites in the world. Family vacation crowds increase but prices remain below peak-season levels. Best for: families, wildlife travelers on a budget, and anyone interested in turtle tours.

Tortuguero is swarming with turtles in August: green, hawksbill, and loggerhead turtles will all be nesting on the Caribbean beaches. Southern-hemisphere humpback whales start swimming up to the southern Pacific near Uvita and the Osa Peninsula. The rain is heavy but quite predictable, with dry mornings ideal for tours. The prices are still lower than the dry season. Best for: wildlife lovers who don't mind rain and want to avoid crowds.

September offers the rainiest time on the Pacific coast, however it is also the driest time on the Caribbean side. The festival of whales at Uvita marks the peak time for whale-hunting and the olive ridley arribada at Ostional, when tens of thousands of turtles come ashore. Hotel prices are at their lowest point of the year. Best for: trips to the Caribbean coast, whale watchers, and budget travelers willing to accept the rain.

The Pacific coast has its heaviest downpour of the year in October. Certain southern areas, especially large parts of the Osa Peninsula, may temporarily shut down due to flooding. On the other hand, the Caribbean coast brings sunshine and good swimming conditions. For experienced surfers, swells are at their most powerful, and accommodation prices are very low. Best for: Caribbean itineraries, surfers, and budget-conscious travellers.

November is often overlooked, but it offers a great balance. The rains gradually ease, the forests remain lush and green, and prices are still relatively low in the first half. Wildlife is active, trails reopen, and migratory birds arrive in large numbers. Ideal for: budget travellers, nature photography, and those wanting green landscapes without heavy rain.

December is like two different months in one. On the one hand, the first couple of weeks will be serene, cost-effective, and beautiful since the dry season is gradually coming back. On the other hand, after the 15th of December, Costa Rica will be stepping into its peak and most expensive period of the year. Hotels must be reserved at least half a year in advance. Besides these, San Jose turns into a magical place by the Festival of Lights the second Saturday of December. Best for: Christmas/New Year travelers who plan their trips way ahead.

Costa Rica is home to about 6% of the world's biodiversity while accounting for only 0.03% of its land area. It has more than 900 species of birds, four species of monkeys, and five species of sea turtles. Therefore, the decision of the best time to visit Costa Rica for wildlife mainly depends on the species in question. December to April is the ideal time to see mammals, birds, and other general viewing activities, especially for wildlife tours in Costa Rica as the trails and visibility are better due to the drier season. However, if you want to see sea turtles nesting and humpback whales, then July to October is the best time as it is the peak season for these activities.

Costa Rica is a premier destination for seeing sea turtles in the wild. However, the best time varies by turtle species and coast. For instance, green turtles nest at Tortuguero from July - October, with the peak in August. The olive ridleys come to Ostional in a mass arribada from August - November. Leatherback turtles lay their eggs in the Pacific region from October to February.

The ideal time to travel to Costa Rica for bird watching is from December to April, making it a highlight of nature travel in Costa Rica since the weather is warmer and the skies tend to be clearer. At this time the birds are also more active as it is the breeding season and the North American migrant birds are coming. The magnificent quetzal is the most elusive bird in Costa Rica and one can find it most easily from late February to May when the birds are breeding in the Monteverde and San Gerardo de Dota areas. Scarlets can be spotted at any time of the year in the Osa Peninsula. October and November are the months when the migratory warblers, hawks, and swallows come in great numbers.

Whale watching is almost year round and a key highlight of adventure travel in Costa Rica because two different species of humpbacks, from two different hemispheres, migrate to the Pacific coast of this country. The humpbacks from the Northern hemisphere arrive from December to April, with the peak being from January to March. Humpbacks from the Southern hemisphere arrive from July - November and the biggest concentration is from August - October. The best places to observe whales are Marino Ballena National Park near Uvita, the Osa Peninsula, and Dominical. The Uvita Whale Festival held every September is a celebration of the arrival of the whales.

Sloths, monkeys, and toucans can be seen just about anytime throughout the country. Almost every visit to a national park with a proper guide will result in seeing some of these. Frogs, especially the red-eyed tree frog and poison dart frogs, are most active during the green season when humidity is at its highest. For a good opportunity to see jaguars, tapirs, or scarlet macaws, you should go to Corcovado National Park at the Osa Peninsula during the dry season (December - April).

Costa Rica ranks among the top destinations in the world with its terrain changing so dramatically from one place to another that it affects what climate each microregion will have. Hence the importance of planning the itinerary in such a way as to coincide with good weather during the visits to particular regions.

The best period to visit Guanacaste and Liberia is from mid-December - April, as there will be almost zero rainfall and plenty of sunshine. Guanacaste is more similar to a tropical dry forest than a rainforest, so the temperature range will be 85 - 95°F and the landscape turns golden by March. Liberia is the international gateway, allowing direct flights from major US cities and easy access to luxury travel in Costa Rica along the Pacific coast. During the green season, the rain here is lighter than in other parts of the country, so late November and early December are a great time to visit.

November to April has the best weather conditions in Tamarindo, with plenty of sun and calm seas. However, the surfers' season is from May - October when the Pacific swells are larger. As a part of Guanacaste, Tamarindo enjoys around 300 sunny days a year and an average temperature range of 86 - 91°F. February accounts for the least precipitation, just 3mm of rainfall. Leatherback turtles come to lay their eggs at Playa Grande from October - February. Christmas, New Year, and Semana Santa should be avoided if you want a less crowded experience.

San Jose and the Central Valley remain dry, sunny, and spring-like from December - April, with temperatures ranging from 75 - 82°F, making it the best time to enjoy the top things to do in San Jose. Situated at 1,170m (3,840ft), the city enjoys a temperate climate throughout the year. The dry season is characterized by the absence of clouds and includes events like the Festival of Lights in December and the National Orchid Show in March. The heaviest rainfall occurs in October (around 990mm).

The Pacific coast offers the best beaches in Costa Rica and dry weather from December - April. Jaco and the southern part of the Osa Peninsula enjoy a stretch of sunny days, perfect for beach lovers. Heavy rain in September and October can make the Osa Peninsula inaccessible due to flooding and road closures. Although Manuel Antonio remains open year-round, the green season brings heavy afternoon rains. Dry months provide a better wildlife experience due to firmer trails and improved visibility.

There are no true dry seasons on the Caribbean coast, meaning it stays lush all year round and the typical Costa Rica weather patterns do not fully apply. However, the driest periods are usually February - April and September - October, the latter being the opposite of the Pacific’s rainiest months. July - October is the best time for green turtle nesting at Tortuguero National Park. Expect warm temperatures, high humidity, and frequent afternoon showers throughout the year.

It can rain at any time in Arenal and Monteverde as it is those rains that nourish the rainforest and cloud forest that have made these regions famous. The driest and clearest days with the most frequent views of Arenal Volcano usually come from February - April. The volcano is often covered with clouds during the green season though. Despite that, many people still choose May - November to visit.

The best places to visit in Costa Rica for first-time visitors are a combination of La Fortuna, Monteverde, and Manuel Antonio, often explored through private guided tours in Costa Rica for 7-10 days, following a single loop starting from San Jose and covering volcanoes, cloud forest, wildlife, and Pacific beaches.

The worst time to visit Costa Rica depends on what you're trying to avoid:

September and October: the heaviest rains in the Pacific, some roads are flooded, the Osa Peninsula is often closed. It's great if you are planning to go to the Caribbean.

Dec 20 - Jan 5: the week with the highest prices. Hotel rooms get booked 6+ months in advance. Semana Santa (late March or early April): domestic travel increases drastically, the beaches are overcrowded, and most of the businesses close.

Due to the combination of humidity, elevation, and tropical rains in Costa Rica, packing wisely counts more than packing a lot. Choose mostly quick-drying fabrics, sun protection, and just one good pair of hiking shoes, especially when planning senior travel in Costa Rica where comfort is key

The best time to visit Costa Rica depends on what you want to get from the trip. From December - April, you can expect regular sunny days and perfect beach conditions. May, June, and November bring the best combination of beautiful nature, affordable prices, and reasonable rainfall. And if seeing sea turtles, humpback whales or traveling along the Caribbean coast is what you are after, then the green season from July - October can be your best time. No matter which you opt for, make your reservations early, bring clothing in layers, and live the pura vida life.Ready to experience Costa Rica the right way? Contact Tailored by Locals.
