Best Time to Visit Costa Rica: A Month-by-Month Guide
There is no single best time to visit Costa Rica — there is a best time for what you want. The country sits close to the equator, so the days stay a similar length all year and it never really has a cold season. What changes is the rain, and with it the crowds, the prices and which parts of the country are at their finest. Once you understand the rhythm of the two seasons, choosing your month becomes much easier.
The two seasons, briefly
Costa Ricans talk about the dry season and the green season rather than summer and winter. The dry season runs roughly from December to April and brings the reliable sunshine most people picture. The green season, from about May to November, brings afternoon rain, lush landscapes and far fewer visitors. Neither is “bad” — they simply suit different trips.
Dry season: December to April
This is the classic time to come. Mornings and afternoons are mostly sunny, the Pacific beaches are at their best, and the roads and trails are easy going. It is also the busiest and priciest stretch, especially from mid-December through the New Year and again around Easter, when Costa Ricans travel too. If you have your heart set on these dates, book well ahead — the best hotels fill months in advance. February and March tend to be gloriously dry and a little quieter than the festive peak.
Green season: May to November
Do not let the word “rainy” put you off. Through much of the green season the mornings are bright and the rain arrives as a warm afternoon downpour that clears as quickly as it came. In return you get a countryside that is impossibly green, waterfalls in full flow, noticeably lower prices and space to yourself at sights that are shoulder-to-shoulder in January. September and October are the wettest months on the Pacific side and the quietest of the year — wonderful value if you do not mind planning around the weather.
The Caribbean plays by its own rules
One quirk worth knowing: the Caribbean coast, around Puerto Viejo and Tortuguero, runs on a different calendar. It can see rain when the Pacific is dry, and — this is the useful part — it is often at its sunniest in September and October, exactly when the rest of the country is at its wettest. If you are travelling in those months and want reliable beach days, the Caribbean is our quiet tip.
Month by month
January and February are peak dry season: sunny, dependable and busy. March and April stay dry and grow hotter, with Easter the one week to book around. May and June open the green season with lush scenery, bright mornings and better value. July often brings a short dry spell locals call the veranillo, or “little summer”, and is a lovely month. August stays green and marks the start of the main whale-watching season on the south Pacific. September and October are the wettest and quietest on the Pacific — and the sunniest on the Caribbean. November is the turning point, with the rains easing and the landscape at its greenest just before high season returns. December begins dry and festive, becoming busy and pricey in the final fortnight.
The best time for wildlife
If a particular animal is the reason you are coming, timing matters. Green turtles nest at Tortuguero from around July to October. Humpback whales appear off the south Pacific in two windows — roughly December to early April, and again from July to early November, the bigger season. The resplendent quetzal is easiest to see during its breeding months, about February to July, in the cloud forests of Monteverde and San Gerardo de Dota. Birdwatching is rewarding year-round, with migratory species adding to the resident cast from around September to April. If wildlife is your priority, tell us which species — we will build the trip around the right season.
Fewer crowds and better value
For the best balance of decent weather, thinner crowds and gentler prices, the shoulder months are hard to beat: May, June and late November sit either side of the wettest period and often deliver bright mornings without the high-season bustle. You will also find that trip length stretches further in the green season, since your budget simply goes further — worth bearing in mind when you decide how many days to spend here.
So when should you go?
The truthful answer is that the best time depends on your priorities — sunshine, wildlife, value or quiet — and often on which regions you want to combine. That is where we come in. Tell us your rough dates and what matters most to you, and we will tell you honestly what to expect and how to make the most of the season. You can start your tailor-made Costa Rica trip or get in touch and we will plan it around the right time of year for you.
