Like many tropical countries, Costa Rica experiences two seasons, the wet and the dry, rather than the four seasons temperate regions are used to. The dry season is generally from about late December to April and this is called verano (or summer) by Costa Ricans.The rest of the year tends to be wet, and is called invierno (or winter).
The Caribbean coastal region tends to be wet all year round. The dry season is characterised by fewer rainy days and spells of fine weather sometimes lasting a week or more.
