Trip Planning - About Costa Rica

The South Pacific has a shorter dry season and experiences more intense afternoon storms than its northern counterpart, the North Pacific. From the end of December until April, the dry season is marked with 75% humidity, and average temperatures of 26°C (79°F) along the coast (average daytime temps of 31°C (88°F) and night time temperatures of 22°C (71°F)). In the lowlands during the rainy season, May through November, 4000mm (157 in.) of rain falls annually and on the Oso Peninsula, more than 5000mm (197 in. - that’s 16.4 feet of rain) of rain falls annually.

This region maintains an average humidity of 75% during the dry season, escalating slightly during the rainy season, reaching 90% in July, October and December. Strangely enough, late June or July typically experiences a "veranillo" (little dry season) with a dramatic decrease in rain but is one of the most humid months.
