In the lowlands during the rainy season, May through November, 4000mm (157 in.) of rain falls annually and on the Osa 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.

Best time to visit Dominical

Contrary to the common believe and the tourism statistic the best time to visit our area is in our opinion the green or rainy season. The reason is that the air is much fresher and clearer due to the afternoon rains and the green season is the time when our area shows the real tropical rain forest with lots of water in the waterfalls and dense lush green foliage and exuberant flowers.

In the dry season Dominical gets dusty and hot and the jungle does not appear as lush and green.
