In short: The best time to visit Costa Rica is December to April — the dry season, with the most reliable sunshine across most of the country. May to November is the green season: warm and lush, with fewer crowds, lower prices and brief afternoon showers. The Caribbean coast runs on its own rhythm, driest in September and October.
After 40 years and more than 50,000 travellers sent to Costa Rica, one question lands in every enquiry: “When should we go?” The answer is never one month. It depends on which coast, which wildlife, your budget, and whether you want a beach or a cloud forest. What follows is our definitive answer — built on experience, not a weather chart.
Weather-wise, because of Costa Rica’s location in the Central American tropics, generally speaking, it is hot, sunny, and more or less humid here all of the time. However, due to the line of steaming volcanoes bisecting the country from north to south, jade-green mountains zigzagging everywhere, and two ocean coastlines, a magical combination of sunshine, rain, altitude, and ocean create countless microclimates. The result is that you can enjoy good weather pretty much all year long in Costa Rica.
Costa Rica has two coasts and two seasons
There are two seasons: dry and rainy. Keep in mind that Costa Rica’s Pacific and Caribbean climates are distinct and quite opposite. From January to April, you’ll find dry season along the Pacific side of the country, which means hot and sunny weather with little rain (although trade winds make it quite windy in January and February). It’s a good time to visit the beaches.
The rainy season starts sometime in May and lasts through November, with a mini-summer dry period in July and early August. Even so, the rainy season usually follows a pattern of sunny mornings with rain showers in the afternoons or evenings, so you’re rarely rained out all day. December tends to be a transition time, with cool trade winds blowing away the rain into the dry season.
The Caribbean side is different.
The Caribbean side of Costa Rica is very different. Trade winds that sweep away rain in the Pacific pile all of that moisture onto the Caribbean, resulting in heavy rains there from December through February. The warm Caribbean Sea brings rain showers most of the year to the Caribbean, which keeps the jungle lush and green. But when the Central Valley and Pacific regions experience daily strong rains in September and October, it’s typically dry, sunny, and beach weather in the Caribbean.
High tourist season runs from Christmas to after Easter, and high prices reflect the demand. If you want to completely avoid the crowds and get great deals, the best time to visit Costa Rica is in the “shoulder seasons” of May to early June, and again from November to mid-December. The mini-summer of July and August is also a good time.
Ready for some adventure?
Costa Rica is known for its adventure tourism, which takes its cue as well from the seasons. Mountain biking, hiking and canopy zip line tours are much more enjoyable during dry season months. Meanwhile, whitewater rafting and surfing get better with rainstorms.
You need to know: Travel insurance when you visit Costa Rica
Few areas of the planet offer the amount of biodiversity found in Costa Rica. Rainforest, cloud forest, and a multitude of other habitats are home to a mind-boggling variety of birds, butterflies, insects, reptiles, amphibians, and unique mammals like jaguars, tapirs, and sloths. National Geographic calls Costa Rica the “seventh most important whale watching hotspot in the world,” with two whale watching seasons – July to October for migrating humpback whales from Antarctica, and December to April for humpback and pilot whales migrating from North America.
If wildlife watching is your main reason to visit, our Northern Costa Rica Birdwatching Experience is designed for nature lovers — 8 days through Caño Negro, Arenal and Monteverde with certified naturalist guides. For a full-country overview with beaches, volcanoes and jungle, the Costa Rica Highlights tour is our most popular 15-day itinerary.
Nature lovers are welcome.
Visiting Costa Rica on a nature vacation will not disappoint. Close to 26% of Costa Rica’s territory is preserved in national parks and private reserves. It is a prime destination to see five of the world’s seven species of sea turtles nesting and hatching – February to October along the Caribbean Coast, especially in the Tortuguero National Park; and from July to March on the Pacific Coast, especially in the Ostional National Wildlife Refuge and Las Baulas National Park in Guanacaste. Bird lovers will delight to see thousands of migrating and native birds, including endangered species like the Jabiru Stork, in wetlands and forests from October to March. February is nesting season for vividly colored Quetzals in the cloud forests.
Overall, there is no bad time to visit Costa Rica. The friendly nation is a place with something for everyone and for every type of getaway.

Costa Rica Month-by-Month: What to Expect
No two months in Costa Rica feel the same. Knowing what each month brings lets you align your trip with the wildlife, conditions, and crowd levels that matter to you. Here is what 40 years of sending travellers here has taught us.
Is December to April the Best Time to Visit?
Yes — if you want guaranteed sunshine and peak wildlife on the Pacific coast. December through April is the dry season on the Pacific side. Skies are clear by 9 a.m. most days. Manuel Antonio, Guanacaste and the Osa Peninsula are at their best. January and February bring trade winds to Guanacaste — ideal for kite surfing, less so for exposed headlands. March and April are the hottest and driest months, with temperatures reaching 34°C in the lowlands. Wildlife congregates around waterholes. Scarlet macaws nest. Humpback whales arrive off the southern Pacific in late March.
Is May to November a Good Time to Visit?
Yes — and for wildlife and value, it’s often better than the dry season. May to November is the green season (formerly called the rainy season). Rain typically arrives as afternoon thunderstorms between 2 p.m. and 5 p.m. Mornings are clear and wildlife-rich. Prices drop 20–30% at most lodges. Crowds disappear. Tortuguero’s green turtle season peaks June through September. The cloud forests in Monteverde are at their most atmospheric. The southern Pacific — Corcovado, Drake Bay, the Osa — receives the heaviest rain but rewards with extraordinary density of wildlife and zero tourists.
July and August bring a short dry period called the veranillo — a predictable break of lower rainfall that many local families use for their own holidays. Sea conditions on the Pacific calm during this window.
Best Time to Visit Costa Rica by Region
Costa Rica’s two coasts operate on opposite weather rhythms. A single trip can experience the dry season and the green season simultaneously, depending on which regions you combine.
What About Monteverde and Cloud Forests?
Yes, Monteverde is worth visiting year-round, but the cloud forests are most atmospheric from May through November. The mist that gives cloud forests their name is a function of daily moisture — fog rolling in from both coasts as air masses collide over the continental divide. In the dry season, visibility is clearer but the magic of the misty forest is reduced. The Resplendent Quetzal is most visible in Monteverde February through May. Cloud forest canopy tours and hanging bridges run every day of the year. Accommodation at Monteverde fills quickly in December and January — book early or visit in the green season shoulder months of May and November.
Should I Visit Guanacaste in High Season?
Guanacaste (the North Pacific) is at its best from December to April — but it is also at its most crowded and expensive. The province’s advantages are most visible in the dry season: white sand beaches, 30°C days, and clear Pacific blue water. Rincon de la Vieja volcano is more accessible, and Palo Verde wetland fills with birds. If you want Guanacaste without the crowds, late November and early December offer near-identical conditions to January but with 30% fewer tourists and more attentive service at lodges.
Is the Caribbean Coast Better in a Different Season?
Yes — the Caribbean follows its own calendar and is often best when the Pacific is at its wettest. The Caribbean coast — including Tortuguero and Cahuita — has no fixed dry season. Its driest months are typically February, March, September and October. This means mid-September and mid-October offer the unusual combination of dry conditions on the Caribbean and a vibrant green season on the Pacific — two distinct ecosystems performing at the same time.
Is Arenal Good Year-Round?
Yes, but the volcano is most often visible in the dry season (December–April) and in the morning hours. Arenal Volcano sits in a zone that receives significant rainfall year-round — roughly 4,000 mm annually. Cloud cover is frequent even in the dry season, though mornings give the best chance of a clear cone. The surrounding rainforest and hot springs are excellent in every season. Night visibility from 6–9 p.m. often produces the best volcano views as cloud levels drop.
When Should I Visit the Osa Peninsula?
February to April is the most accessible, but September and October are when the wildlife is exceptional with minimal crowds. The Osa Peninsula — home to Corcovado National Park — is one of the most biodiverse places on earth. It is also one of the wettest. Trails during the peak rain months (September–October) can be challenging, but the reward is extraordinary: tapirs, scarlet macaws, poison dart frogs, and spider monkeys in concentrations that make other national parks look empty. Drake Bay and Caño Island diving are best from December to May.
Best Time to Visit Costa Rica for Wildlife
Wildlife in Costa Rica does not take a season off, but specific encounters depend entirely on your timing. Forty years of naturalist guiding have taught Horizontes which species peak in which months. Here is what makes each season worth planning around.
Sea Turtle Nesting: When and Where?
Tortuguero on the Caribbean coast is the best place on earth to watch green sea turtles nest, from June through October. Peak activity is July and August, when thousands of females come ashore at night. Leatherbacks arrive earlier — March through May — on both Caribbean and Pacific beaches, including Playa Grande in Guanacaste. All turtle watching at Horizontes is guided, low-impact and coordinated with local conservation groups — never the mass beach tours that disturb nesting.
Whale Watching: Which Season Is Best?
Humpback whales visit Costa Rica twice a year, making it one of the only places on earth with both Northern and Southern Hemisphere populations. Southern Hemisphere humpbacks arrive July through October off the southern Pacific coast — Drake Bay, Marino Ballena National Park. Northern Hemisphere whales come December through April in the same zone. August is peak season with both populations potentially overlapping. Orca sightings occur year-round along the Pacific.
Birding: Is Costa Rica Worth It Year-Round?
Yes — Costa Rica has 928 bird species and excellent sightings in every month. The Resplendent Quetzal is most visible February through May in Monteverde and the Cerro de la Muerte highlands, when males display long tail feathers during breeding season. September through December brings migrating species from North America. The Caribbean lowlands host specialties unavailable elsewhere in the country — great green macaws, snowy cotingas, sunbitterns — best reached in the Caribbean’s drier window of February to March or September to October.
Best Time to Visit Costa Rica by Travel Style
The right time depends as much on what you want to do as on the weather. Here is how the seasons align with the most common reasons people travel to Costa Rica with Horizontes.
Honeymoon and Romantic Travel
Late November to January offers the best combination of dry season reliability, post-peak-season prices, and empty beaches. The Pacific coast is settling into its dry season but the extraordinary crowds of Christmas and New Year haven’t arrived yet. Our Costa Rica honeymoon itinerary is most popular with couples travelling in this window and in April.
Family Travel with Children
July and August align with European and North American school holidays and coincide with the veranillo break in Costa Rica. Sea turtle watching in Tortuguero is at peak activity. Wildlife is abundant and accessible. Beach conditions on the Pacific central coast are good. A 10-day family itinerary works well in this window.
Budget Travel and Value Seekers
May, June and October offer the best rates of the year at premium lodges — often 25–30% below high season prices — while the wildlife and experience quality remain identical to peak months. Cloud forest and Caribbean routes are excellent in these months. Our green season guide explains exactly what to expect month by month with pricing guidance.
Plan Your Costa Rica Trip Around the Right Season
Once you know your ideal travel window, the next step is building the route. The season you choose directly affects which regions are accessible, which wildlife is active, and how to structure your days. For a full breakdown of routes that work year-round, see our complete Costa Rica itinerary guide — it covers 5, 7, 10, 12, and 14-day options with specific guidance on how the dry and green seasons affect each leg of the journey.
If you’re considering travelling between May and November, our green season guide goes deeper on what to expect month by month, where prices drop, and which wildlife encounters peak during the rainy season. Many of Horizontes’ most memorable trips are made in the green season — fewer crowds, lower prices, and landscapes at their most vivid.
For shorter trips timed around the dry season, the 5-day Costa Rica itinerary and 7-day Costa Rica itinerary are built around the regions most accessible outside the rainy months — Arenal and Manuel Antonio hold up well in both seasons, while the Osa Peninsula and Tortuguero are better reserved for dry season or shoulder months.
Horizontes has been designing Costa Rica journeys since 1984. Our team is based in San José and we have first-hand knowledge of every lodge, route, and season covered in this guide.

Frequently Asked Questions About When to Visit Costa Rica
What month is the cheapest to visit Costa Rica?
May, June and October are consistently the cheapest months, with lodge rates 20–30% below peak season. These months fall in the green season (rainy season), but weather is typically clear in the mornings with afternoon showers — not all-day rain. Wildlife is excellent and crowds are minimal.
Is January a good month to visit Costa Rica?
Yes. January is one of the best months to visit the Pacific coast and central regions. The dry season is fully established, beaches are calm, and wildlife activity is high. The only downside is that trade winds pick up in Guanacaste from January through March, making some northern Pacific beaches windy.
Is it safe to visit Costa Rica during hurricane season?
Costa Rica sits outside the main hurricane belt and is rarely hit directly. The Caribbean side can experience tropical storm influence between June and November, but the Pacific coast is largely unaffected. Even during heavy rain months, most Horizontes itineraries run normally — we have operated every single year since 1984, including all weather events.
How many days do you need in Costa Rica?
Ten days covers the four main regions comfortably. Seven days works with careful routing and two or three regions. Five days gives you a focused two-region experience. Fourteen days or more opens up the Osa Peninsula, Caribbean, and the country’s lesser-visited highlands.
