Wondering about the best time to go to Costa Rica? The short answer: the dry season (roughly mid-December to April) is the most popular for reliable sunshine, while the green season (May to November) is lusher, cheaper and quieter. But the real answer depends on where you’re going and what you want to do, because Costa Rica’s regions run on surprisingly different rhythms. Costa Rica is one of our home bases, and we’ve spent years here across the seasons. Max grew up in the country, so the timing advice is genuinely lived. This is our first-hand, region-aware guide to the best time to visit Costa Rica, month by month.
Key Takeaways
- Dry season (mid-Dec to April) is the most popular, with reliable sunshine, especially in Guanacaste, but the highest prices and crowds.
- Green season (May to November) is lush, quiet and cheaper, with warm mornings and afternoon rain; September–October are the wettest (and cheapest).
- The best month depends on your goal: whales, turtles, surf, fewer crowds or lowest prices each point to a different window.
- The Caribbean runs on the opposite rhythm to the Pacific, driest around September–October and February–March.
- Our sweet spot is the shoulder months (late November and May), for good weather with fewer crowds and lower prices.
Best Time to Visit Costa Rica at a Glance
| Dry season | Mid-December to April (peak, sunniest) |
| Green season | May to November (lush, cheaper, afternoon rain) |
| Best overall | The shoulder months: late Nov & May |

Costa Rica has two seasons, not four: a dry season and a green (rainy) season. But “rainy” rarely means all-day rain, it usually means sunny mornings and a heavy afternoon downpour, and the timing shifts by region. This guide breaks down the two seasons, a month-by-month table, the best time by region, and the best time for specific activities, so you can pick the window that matches your trip.
Dry Season vs Green Season in Costa Rica
The single biggest decision is dry season versus green season, and it’s a genuine trade-off rather than a right answer.
Dry season (mid-December to April)
The dry season is Costa Rica’s peak: reliable sunshine, calm seas and the easiest travel conditions, especially in Guanacaste and the Nicoya Peninsula, which stay driest longest. It’s the best time for beach weather and dependable itineraries, but also the busiest and most expensive, with Christmas, New Year and Easter (Semana Santa) the absolute peaks. Book ahead for those peaks. Our guide to the best beaches shows where the dry-season sun shines brightest.
One thing worth knowing: “dry” is relative to region. Guanacaste can go weeks without a drop, while the south Pacific and the cloud forests still see the odd shower even in March. The trade-off in the dry season is simple, you pay the most and share the beaches with the most people, but you get the most dependable weather, which matters if your trip is short or built around specific beach days.
Green season (May to November)
The green (rainy) season turns Costa Rica impossibly lush, waterfalls run full, the rainforest is at its greenest, and prices and crowds drop sharply. Mornings are typically bright and sunny, with rain arriving in the afternoon, so you can still pack in plenty. The exceptions are September and October, the wettest months on the Pacific (and the cheapest). Even then, exploring in the rain has its own magic, and the country’s waterfalls are at their most dramatic. Just pack a rain jacket and expect the odd river crossing on back roads.
The green season is our quiet secret for value travellers. Hotels drop their rates, tours have space, and the landscapes are at their most vivid. A typical green-season day looks like a bright, warm morning for hiking, a beach or a wildlife walk, then an afternoon downpour that clears the air (and is a fine excuse for a coffee or a hammock). July even brings a short mid-season dry spell locals call the “veranillo”, a mini summer in the middle of the rains.
Costa Rica Weather Month by Month
Here’s the best time to visit Costa Rica broken down month by month, with our honest verdict on each.
| Month | Weather | Crowds / price | Verdict |
|---|---|---|---|
| January | Dry, sunny, breezy | High (post-holiday) | Excellent, peak dry season |
| February | Dry, sunny | High | Excellent, driest month |
| March | Dry, hot, sunny | High | Excellent, hottest & driest |
| April | Dry, hot; rain builds late | High (Easter peak) | Great; book around Semana Santa |
| May | Green season begins | Lower | Sweet spot: lush + fewer crowds |
| June | Sunny mornings, afternoon rain | Low | Good value, green & quiet |
| July | Brief “veranillo” dry spell | Moderate | Good; a mini dry break mid-green |
| August | Afternoon rain; whales | Moderate | Good; whale season starts |
| September | Wettest (Pacific) | Lowest | Cheapest & quietest; Caribbean shines |
| October | Wettest (Pacific) | Lowest | Cheapest; great for the Caribbean |
| November | Rain eases late month | Low → rising | Sweet spot late month |
| December | Dry season returns mid-month | Rising to peak | Great from mid-Dec; holiday peak |
Best Time to Visit Costa Rica by Region
Here’s the nuance the generic guides miss: “best time” isn’t the same across the country. Costa Rica’s regions have genuinely different climates, and this is where our first-hand knowledge helps.
Guanacaste and the North Pacific
Guanacaste (Tamarindo, the Nicoya Peninsula, Papagayo) has the longest, most reliable dry season, sunny and hot from December well into April, and it’s the surest bet for beach weather. In the green season it’s still drier than the rest of the country. It’s our top pick for dependable sun.
The Central and South Pacific
Manuel Antonio, Dominical and Uvita are lusher and get more rain than Guanacaste, with a wetter green season but gorgeous rainforest-meets-beach scenery. The dry season is glorious here; September–October are the wettest. This coast is also the whale-watching heartland (see the activity section below).
The Caribbean coast
The Caribbean (Puerto Viejo, Cahuita, Tortuguero) runs on a completely different, almost opposite rhythm to the Pacific. Its driest, sunniest windows are roughly September–October and February–March, exactly when the Pacific is at its wettest. So if you’re visiting in the Pacific’s rainy peak, the Caribbean is the smart move. The official Costa Rica Tourism Board is a good reference for regional climate and events when you fine-tune the dates. The Caribbean is also warmer and more humid than the Pacific, with Afro-Caribbean culture and some of the country’s clearest water, a genuinely different trip that happens to peak when the Pacific doesn’t.
The cloud forests and highlands
Monteverde and the higher-elevation highlands are cooler, mistier and damper year-round, that mist is the whole point of a cloud forest. There’s no truly “dry” cloud forest, but the drier months (January to April) bring the clearest views. Pack layers whatever the season, as the highlands can feel genuinely chilly compared to the coast, and a light rain layer is useful any month of the year.
The upshot is that Costa Rica is small but climatically varied: you can drive from a sunny Guanacaste beach to a misty cloud forest to a rainy Caribbean town in a single long day, crossing seasons as you go. That’s why matching your month to your main region matters more than the calendar alone.
Best Time to Visit Costa Rica for Specific Activities
If your trip has a specific goal, the best time narrows. Here’s when to go for the big ones.
| Goal | Best time | Why |
|---|---|---|
| Whale watching | Jul–Oct & Dec–Mar | Two humpback seasons overlap on the south Pacific |
| Turtle nesting | Jul–Oct (arribadas) | Peak nesting on the Pacific & Caribbean |
| Surfing | Green season (May–Nov) | Bigger, more consistent Pacific swell |
| Fewer crowds | May, Sept–Nov | Green season, especially Sept–Oct |
| Lowest prices | September–October | The wettest, cheapest, quietest window |
| Best beach weather | January–April | Peak dry season, especially Guanacaste |
For the water-based activities, our guides to whale watching in Costa Rica and the best surfing in Costa Rica go deeper on the seasons. Turtle-nesting arribadas are a green-season highlight worth timing a trip around. If wildlife is your priority overall, the good news is that Costa Rica delivers year-round, sloths, monkeys, toucans and frogs are out in any season, so you rarely need to plan around them.
Whatever month you visit, a car is the most flexible way to explore Costa Rica’s regions, and in the green season a 4×4 handles the wetter back roads and the occasional river crossing.
We use and recommend Vamos Rent-A-Car, a local company with transparent all-in pricing (mandatory insurance included) and 4x4s built for Costa Rican roads in any season.
When We’d Go
After years in and around Costa Rica, here’s our honest take: the shoulder months are the sweet spot. Late November, once the heavy rains ease, and May, at the start of the green season, both deliver good weather with far fewer crowds and noticeably lower prices than the December-to-April peak. If you want guaranteed sunshine and don’t mind the crowds and cost, aim for January to April in Guanacaste. If you want value, lush landscapes and full waterfalls, embrace the green season and simply plan mornings for activities. And if you’re travelling in September or October, base yourself on the Caribbean coast, where the sun is shining while the Pacific pours. Plan the rest with our two-week Costa Rica itinerary and where to stay guides.
How Far Ahead to Book
Timing the booking matters almost as much as timing the trip. For the December-to-April dry season, and especially the Christmas, New Year and Easter peaks, book flights and hotels several months ahead, as the best places in Guanacaste and Manuel Antonio sell out and prices climb. The green season is far more forgiving: rates are lower, availability is good, and last-minute deals are common. A rental car is worth booking ahead too, particularly a 4×4 in the green season, when the best-value vehicles go quickly.
