Climate of Costa Rica

Costa Rica is a tropical country and experiences only two seasons: wet and dry. The dry season is generally between late December and April, and the wet season lasts the rest of the year. The Caribbean coast tends to be wet on and off throughout the year. The temperatures vary little between the two seasons; the main influence on temperature is altitude.

San José at 1150m (3772ft) has a climate that the locals refer to as 'Eternal Spring': lows average 15°C (60°F); highs average 26°C (79°F). The coasts are much hotter, with the Caribbean averaging 21°C (70°F) at night and over 30°C (86°F) during the day; the Pacific is a few degrees warmer still. The humidity at low altitudes contributes to the wet climate.
