One of the most pleasant surprises about Costa Rica is that there is no single "Costa Rica weather." Pack this small country with mountains, two coastlines, and rainforest, and you get an astonishing variety of climates — which means you can quite literally choose your ideal weather. Here is how Costa Rica's climate works and how to pick the right spot for you.
Two Seasons, Not Four
Costa Rica does not have spring, summer, fall, and winter. It has two seasons:
- Dry season (December–April): "Summer" (*verano*) — sunny, warm, and the peak tourist period. Blue skies dominate, especially on the Pacific side.
- Green season (May–November): "Winter" (*invierno*) — lush and rainy, typically with sunny mornings and afternoon downpours. September and October are the wettest months, particularly on the Pacific coast.
The green season is not the washout newcomers fear. Most days bring bright mornings, a heavy afternoon rain, and clear evenings — plus lower prices and greener landscapes.
A Country of Microclimates
Here is the remarkable part: Costa Rica packs roughly 12 distinct microclimates into an area smaller than West Virginia. Elevation, mountains, and which coast you are near change the weather dramatically over short distances. In one well-known example, the town of Tronadora gets about 50% less rain than the expat town of Nuevo Arenal just across the lake.
This is great news. It means you are not choosing "Costa Rica's climate" — you are choosing *your* climate.
Climate by Region
Central Valley (San José, Escazú, Atenas, Grecia): Thanks to elevation (2,200–5,000 ft), an "eternal spring" of 60–80°F year round. Warm days, cool nights, low humidity, and rarely any need for air conditioning. The most popular region for retirees largely because of this climate.
North Pacific / Guanacaste (Tamarindo, Flamingo, Nosara): The country's sunniest, driest belt. Hot — daytime highs in the high 80s to low 90s — with a pronounced dry season and ocean breezes. Air conditioning is standard.
Central & South Pacific (Manuel Antonio, Dominical, Uvita): Hot and more humid than Guanacaste, with lush rainforest and more rain, especially in the green season. Beautiful and wild.
Caribbean (Puerto Viejo, Cahuita): Warm, humid, and green much of the year with a different rain pattern than the Pacific (it can rain in any month). Fewer expats settle here, but those who do love its laid-back, multicultural vibe.
Mountain & cloud forest (Monteverde, San Gerardo): Cooler, misty, and green — sweaters required at night. A niche choice for those who love crisp mountain air.
Choosing Your Climate
| You want... | Consider... |
|---|---|
| Cool, spring-like, no A/C | Central Valley |
| Hot, sunny beach, dry season | Guanacaste |
| Lush rainforest near the beach | Central/South Pacific |
| Laid-back, off-the-beaten-path | Caribbean coast |
| Cool mountain air | Monteverde / highlands |
Practical Tips for Newcomers
- Visit in both seasons if you can. A town in February feels very different in October.
- Mind the elevation. A few hundred meters up can mean a noticeably cooler, drier home.
- Plan for the green season. Roads, especially unpaved ones, get muddy; a higher-clearance vehicle helps in rural beach areas.
- Humidity matters as much as temperature. Many retirees find the Central Valley's low humidity more comfortable than coastal heat.
