Costa Rica's year round climate is pleasant with naturally occurring breezes, cooling down most of the coastal areas. Temperatures in the highlands and mountains are not so cold, especially during the day, producing an "eternal spring" feeling.

The average annual temperatures range from 31.7°C (89°F) on the coast to 16.7°C (62°F) inland. The rainy or green season lasts from May to November with noticeably drier days during the rest of the year.
