Best Time to Visit Costa Rica: A Pacific Coast Guide by Season and Goal

5 min read · Tamarindo Estuary Tours Mi Rey

Ask ten people about the best time to visit Costa Rica and you will hear ten answers, because this small country holds very different climates. We run boat, kayak and turtle tours from Tamarindo, on the North Pacific coast of Guanacaste, and we see the seasons change the estuary week after week. This guide answers the question from our side of the map: the Pacific beaches where most travelers who fly into Liberia spend their vacation.

Short answer: for the North Pacific beaches, the best time to visit Costa Rica is the dry season, from December to April, with sunny days and very little rain. The green season, from May to November, brings afternoon showers, fewer visitors and the most sea turtle activity, and many travelers prefer it. Wildlife tours run all year; only the details change.

Dry season vs green season in Costa Rica, seen from Guanacaste

Costa Rica does not have four seasons. The year is divided by rain, and the timing is not identical across the country:

North Pacific (Guanacaste): the driest region, with a clear dry season from roughly December to April and a green season from May to November.
Central and South Pacific: a similar calendar, with more rain overall and greener forest all year.
Caribbean coast: a pattern of its own, where rain is possible in almost any month; September and October are often among its drier months.
Mountains and the Central Valley: cooler than the coast in every season.

On our coast, the green season rarely means rain all day. Mornings are often bright and showers arrive in the afternoon or evening, except in September and October, the wettest months. For the local detail, read our guide to the best time to visit Tamarindo, which covers the town’s weather month by month.

Best time to visit Costa Rica for beaches

If your trip is about sun, sand and swimming, aim for February to April, the driest stretch on the Pacific coast. December and January are mostly dry too, with breezier afternoons as the trade winds pick up.

The green season has its own beach appeal: emptier sand, a green backdrop and colorful sunset skies after an afternoon shower. Plan beach time for the morning and keep the afternoon flexible. In any season, ask about currents before you swim, and never swim near a river mouth or estuary, where crocodiles live.

Best time to visit Costa Rica for wildlife

Wildlife is there all year; the season changes how and where you see it. On the Tamarindo estuary, our guides notice the difference from one month to the next:

Dry season: the tropical dry forest drops many of its leaves, so howler monkeys and birds are easier to find in the bare branches. From roughly October to April, migratory birds from North America add variety along the mangrove.
Green season: the mangrove and the forest turn deep green, and inland rivers and waterfalls carry more water.
Crocodiles: American crocodiles live in the estuary all year, so there is no crocodile season. Boat and kayak tours leave with the high tide, which changes every day.
Sea turtles: nesting on the North Pacific is strongest in the second half of the year. Arribadas at Ostional run mainly from August to December, with peaks from September to November, and the leatherback season at Playa Grande runs from about October to February, although leatherback sightings are now rare.

If nesting turtles are the main goal, plan for the green season and read our guide to the Costa Rica turtle nesting season. No honest operator can guarantee a wildlife sighting, in any month.

Best time to visit Costa Rica with kids

Families usually travel when school allows, so the real question is how to make those weeks work:

Christmas, New Year and spring break: dry, sunny and the busiest weeks of the year on the Pacific. Book flights, lodging and tours well ahead.
Easter week (Semana Santa): one of the busiest weeks for Costa Rican families at the beach.
June to August: green season, with fewer visitors. July often brings the veranillo, a drier spell, but it is also the Costa Rican mid-year school holiday.

Short outings suit children best in any season: a 2-hour boat tour or a late-afternoon turtle release fits around naps and meals. Our guide to Costa Rica tours for families covers which tours fit each age.

Month by month on the North Pacific coast

Each month has its own page with weather, crowds and tours. A quick overview:

January: dry, sunny and busy, with breezy afternoons.
February: one of the driest months and long beach days.
March: hot and dry, spring break visitors and the dry forest at its barest.
April: the end of the dry season; Easter week falls in March or April.
May: the first rains turn the landscape green and the crowds thin out.
June: the green season settles in and turtle nesting increases.
July: the veranillo dry spell and Costa Rican school holidays.
August: the main arribada season at Ostional begins.
September: one of the wettest months and a peak for arribadas.
October: still wet; the leatherback season begins at Playa Grande.
November: the rain eases, the high season begins and the sunset turtle release starts on November 12.
December: the dry season returns and the holidays fill the coast.

Crowds, prices and getting there

The international high season runs from about November to Easter week, and demand peaks at Christmas, New Year and Easter. From May to November, except in July, the Pacific coast is calmer and shared tours often run with smaller groups.

For Guanacaste, flying into Liberia (LIR) puts you about an hour to an hour and a half from Tamarindo by road, and many routes from the United States and Canada land there, especially in the high season. San José (SJO) often has more flight options, but the drive to the Pacific beaches takes several hours.

Booking tours in any season

The Tamarindo estuary tour by boat runs all year: $40 per person, 2 hours, with a bilingual guide, water, fruit and pickup from Tamarindo or Langosta. The departure follows the high tide and we confirm it by WhatsApp after you book.
In nesting season, the night Tamarindo turtle tour costs $60 per person, with pickup in Tamarindo at 5:30 pm.
Online you pay only a deposit; the balance is paid in cash, in US dollars or colones, on the tour day. Cancel at least 24 hours ahead and the deposit is refunded.

Whatever month you choose, Tamarindo Estuary Tours Mi Rey can help you match the tours to your dates. Book online with a deposit, or send us your travel dates on WhatsApp and we will tell you what the tides and the season look like that week.
