Weather in Costa Rica

Each region of Costa Rica is a bit different in terms of average temperatures and rainfall due to elevation and proximity to the ocean, but most follow the same general pattern. The driest and warmest months of the year are December through April. The wetter "green season" in Costa Rica runs from May through November. However, rain showers are a refreshing occurrence throughout the year, so it is important to be prepared for any kind of weather. The Pacuare River levels are dramatically affected by the rainfall during the months of May through October and it is possible that the canyon may be closed due to extremely high water levels. If this is the case, ground transportation will be provided by land to the Pacuare Lodge in place of coming in by river.
