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

Q: What is the best time to visit Costa Rica?

The best time to visit Costa Rica is the dry season, December to April, for reliable sunshine and beach weather. If you want lower prices and fewer crowds, the green season (May to November) is excellent value, with sunny mornings and afternoon showers. May and late November are the best all-round shoulder months, balancing good weather, low crowds and lower prices.

Q: What are the rainy season months in Costa Rica?

Costa Rica's green (rainy) season runs from May to November, with the heaviest rain in September and October on the Pacific side. Rain usually falls as a heavy afternoon or evening downpour rather than all day, so mornings are typically sunny and good for activities. The Caribbean coast is the exception - it is often driest in September and October.

Q: What is the cheapest month to visit Costa Rica?

September and October are the cheapest months to visit Costa Rica, because they are the wettest on the Pacific coast, so hotels and tours cut prices to fill rooms. May, June and November are also good value. The most expensive time is mid-December to April, peaking over the Christmas holidays and Easter week.

Q: Is Costa Rica worth visiting in the rainy season?

Yes. The green season brings lush landscapes, full waterfalls, active wildlife (whales, nesting turtles, birds), far fewer crowds and discounts of 30 to 50 percent. Rain is mostly limited to the afternoon, leaving sunny mornings for excursions. The main trade-offs are humidity and some muddy remote roads, and the peak-rain months of September and October on the Pacific.

Q: What is the best month for weather in Costa Rica?

February is generally the best month for weather - it is the driest, sunniest month across most of the country, with minimal rain and warm temperatures. January and March are almost as good. All three fall in high season, so expect higher prices and busier beaches and parks.

Q: When is the best time for whale watching in Costa Rica?

The best whale watching is July to November on the South and Central Pacific coast, with September the peak month when humpbacks from both hemispheres overlap near Marino Ballena and the Osa Peninsula. Guanacaste also has a second window from December to March. September uniquely combines peak whales with the year's lowest prices.

Q: When do sea turtles nest in Costa Rica?

Green turtles nest at Tortuguero on the Caribbean coast from July to October. Olive ridley turtles arrive in mass arribadas at Ostional on the Nicoya Peninsula from August to November, peaking in September. Leatherbacks nest at Playa Grande from October to March. So roughly July to March offers turtle nesting somewhere in the country.

Q: What is the worst time to visit Costa Rica?

There is no truly bad time, but the peak Christmas-New Year window (mid-December to early January) is the most crowded and expensive, and Easter week (Semana Santa) is similarly busy as locals travel too. For pure weather, the wettest weeks of September and October on the Pacific can disrupt beach plans - though the Caribbean is often sunny then.

Q: What is the temperature in Costa Rica year-round?

Coastal Costa Rica stays warm all year, roughly 75 to 82 degrees Fahrenheit (24 to 28 Celsius), with high humidity in the green season. The Central Valley and San Jose are cooler and spring-like, around 68 to 78 Fahrenheit, while high-altitude cloud forests like Monteverde are cooler and often misty. Season affects rainfall far more than temperature.

Q: How many days do you need in Costa Rica?

Most travellers find 7 to 10 days ideal - enough to combine a volcano or cloud-forest area (like Arenal or Monteverde) with a Pacific beach, without rushing. Two weeks lets you add the Caribbean coast or the remote Osa Peninsula. Because roads are slow and winding, budget more transit time than the map distances suggest.

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

Costa Rica has two seasons — a dry season and a green (rainy) season — and the “best” time depends on what you want. For reliable sunshine and beach weather, come in the dry season (December–April). For lush landscapes, active wildlife, fewer crowds and lower prices, come in the green season (May–November). Below is a full month-by-month and region-by-region breakdown so you can pick the right window for your trip.

Quick answer: when to go to Costa Rica

Best weather: December to April (dry, sunny, peak season). Best value: May and September–October (green season, big discounts, fewer people). Best all-rounder: May and late November — shoulder months with mostly sunny mornings, low crowds and lower prices. Temperatures sit around 75–82°F (24–28°C) at the coast all year.

Dry Season vs Green Season: Which Is Better?

Costa Rica doesn’t have a hot-and-cold cycle like temperate countries — it has a dry season and a wet (green) season, split by how much rain falls. Both are good times to visit; they just suit different trips.

A key myth about the “rainy” season

Green season rarely means all-day rain. Mornings are usually sunny — ideal for excursions — and the rain arrives as a heavy afternoon or evening downpour that clears. Many travellers get the best of both worlds: green landscapes, active wildlife, and half-price hotels, with plenty of dry hours to enjoy.

Costa Rica Weather Month by Month

Here’s what to expect in each month, using Central and Pacific Costa Rica as the baseline (the Caribbean coast runs on a different rhythm — see the regional section below). Rainfall figures are approximate monthly averages for the Central Pacific.

Month	Season	Rain	Crowds	Price	Good for
January	Dry	Very low	High	High	Sun, beaches, wildlife
February	Dry	Very low	High	High	Driest month, great all-round
March	Dry	Low	High	High	Beaches, surfing (beginners)
April	Dry	Low (rising)	High (Easter)	High	End of dry season, warm seas
May	Green	Moderate PM	Low	Lower	Best value, green & sunny AM
June	Green	Moderate	Low	Low	Value, birding, waterfalls
July	Green	Lower (“veranillo”)	Moderate	Moderate	Mini-dry spell, whales begin
August	Green	Moderate–high	Moderate	Moderate	Whales, turtles, surf
September	Green	Highest	Very low	Lowest	Whales (peak), cheapest, quiet
October	Green	Highest	Very low	Lowest	Caribbean sun, surf, deals
November	Green → Dry	Falling	Low	Lower	Green + drying out, great value
December	Dry	Low	High (late)	High	Sun returns, festive, busy

Month-by-month weather, crowds and pricing for Costa Rica (Central/Pacific baseline).

Rainfall is minimal December–April and peaks in September–October. Note the small July dip — the “veranillo” or little summer.

The pattern is clear: rain is negligible from December through April, builds through the green season, and peaks in September and October — which is exactly why those two months are the cheapest and quietest. A brief drier spell called the veranillo (“little summer”) often lands in July.

Best Time to Visit Costa Rica by Region

Costa Rica is small, but its microclimates are dramatic. The Pacific side and Caribbean side often have opposite weather on the same day, so the best month depends heavily on where you’re going.

Sunny palm-fringed Pacific beach in Guanacaste, Costa Rica during the dry season — Guanacaste and the north Pacific are reliably sunny in the dry season, December to April.

Guanacaste & the North Pacific (Tamarindo, Nosara, Papagayo)

This is Costa Rica’s driest, sunniest region and the classic beach destination. The dry season (December–April) is reliably hot and rain-free — perfect for beaches — though the landscape turns brown by March. Green season brings the hills back to life and cuts prices sharply; even then, the north Pacific gets less rain than the south. Best: December–April for sun; May & November for value.

Central Valley & San José (Arenal, Monteverde nearby)

The highlands around San José enjoy spring-like temperatures year-round. The dry season (December–April) is the most comfortable for city and volcano visits. Monteverde cloud forest, however, is misty and can rain in any month — that mist is the attraction, so don’t rule out green season. Arenal is lush and rainy most of the year; visit in the dry season for the clearest volcano views.

Central & South Pacific (Manuel Antonio, Osa Peninsula, Dominical)

Wetter and more jungly than the north, this region rewards wildlife lovers. The dry season is gorgeous; the green season delivers the country’s best whale watching (July–November) and roaring surf. The Osa Peninsula (Corcovado) is spectacular year-round but harder to reach in the wettest months. Best: December–April for ease; August–October for whales and surf.

Caribbean Coast (Puerto Viejo, Tortuguero)

The Caribbean side breaks all the rules: its driest, sunniest windows are February–March and September–October — meaning when the Pacific is at its wettest (Sep–Oct), the Caribbean is often at its best. This is the sweet spot for a green-season trip. Tortuguero’s green turtles nest July–October. Best: September–October — sunny Caribbean while the rest of the country is discounted.

Best Time for Wildlife & Activities

If your trip is built around a specific experience, let the wildlife calendar choose your month.

Experience	Best months	Where
Whale watching	Jul–Nov (peak Sep); Dec–Mar	South/Central Pacific; Guanacaste
Green turtle nesting	Jul–Oct	Tortuguero (Caribbean)
Olive ridley arribadas	Aug–Nov (peak Sep)	Ostional (Nicoya)
Leatherback nesting	Oct–Mar	Playa Grande (Las Baulas)
Surfing (beginners)	Dec–Apr	Tamarindo, Jacó
Surfing (experts, big swell)	May–Oct (peak Sep–Oct)	Pacific coast
Birdwatching (incl. quetzals)	Dec–Apr (nesting)	San Gerardo de Dota, cloud forests
Fewest crowds & lowest prices	Sep–Oct	Nationwide
Best beach weather	Dec–Apr	Guanacaste & Pacific

Best months for Costa Rica’s signature wildlife and activities.

The whale-watching sweet spot

September is the single best month for whales: humpbacks from both the Northern and Southern hemispheres overlap along the South Pacific coast (Marino Ballena, Osa). It’s also the cheapest month to travel — a rare win-win of great wildlife and low prices.

When Is the Cheapest Time to Visit Costa Rica?

The cheapest months are May, June, September and October, with September–October the absolute lowest — these are the wettest months on the Pacific, so hotels and tours slash rates to fill rooms. Peak pricing runs mid-December through April, spiking hardest over the Christmas–New Year holidays and Easter week (Semana Santa), when prices and crowds are at their maximum and hotels book out months ahead.

Travel window	Crowds	Price level	Verdict
Dec 15–Jan 3 (holidays)	Highest	Peak +	Book early or avoid
Jan–Apr (dry)	High	High	Best weather, pay for it
Easter week (Semana Santa)	Very high	Peak +	Locals travel too — busy
May, June, November	Low	Lower	Best value
Sep–Oct (wettest)	Lowest	Lowest	Cheapest; great for Caribbean

Costa Rica travel windows by crowd level and cost.

Book far ahead for the December holidays

Mid-December to early January is the busiest and priciest window of the year. If you must travel then, reserve hotels, popular tours and domestic flights several months in advance — the best lodges sell out, and last-minute rates are steep. The same applies to Easter week.
