Weather in Costa Rica… Sunny season is not always sunny everywhere in Costa Rica… Rainy season is not always rainy everywhere in Costa Rica… Nature, rainforests, wildlife, happy people… Oh Yes! Those are permanent!
Well! It is officially sunny season now! So you may think that wherever you go in Costa Rica, the weather will be sunny and dry, blue skies everywhere… No need for the rain poncho or the umbrella! Hmmm… Wrong! Depending on where you go you may find some pouring rains and chilly winds.

This calendar may seem a bit complicated, but it is important to realize that in the tropics there are no weather fixed rules. January and February can be influenced by North cold fronts (And now and then even March). September and October by hurricanes, and December by the trade winds… Always recommend rain gear! No matter what!
