Costa Rica Weather & Climate
The Costa Rican climate is among the finest in the world. Seasonal variations in Costa Rica’s weather are typically quite minimal, and the average temperature is a very comfortable 74°. During the months of December, January, and February, the northerly breeze brings with it the faintest echo of the North American winter, but otherwise, the weather patterns are quite temperate and predictable year-round.
The greater deviation in temperatures and humidity comes from either the elevation that you’re at, or how close you are to the ocean. For instance, in the highlands, the average temperature hovers between 50 to 55°, while at sea level, the average temperature is about 80°.
The rainy or “green” season lasts from May through November. The Costa Rican locals refer to this season as their winter due to the heavier than usual amount of precipitation. Rainstorms usually occur in mid-afternoon, and are usually brief, torrential downpours. There’s a saying amongst natives that the more brightly the sun shines at sunrise during this season, the more intensely it will rain the following afternoon.
In planning your wardrobe for your visit, lighter weight clothing is recommended. A sweater or rain jacket is usually the only outerwear you’ll need unless you’re planning on spending more time in the higher elevations. There you’ll want to add a few medium weight clothing articles. In any case, the sun is warm and bright, so bring your sunglasses and a shade hat.
