Reading Costa Rica Rainfall Charts
You may not have seen charts like this before, but they are very easy to read. The more of a month that is covered by the blue rainfall blob, the more it rains that month. The red triangles highlight the month of August. In Jacó it rains much less (about 10") than it does in Corcovado (over 20"). Both locations are relatively dry December through March.©

 

 

You can see at a glance that Corcovado has a longer wetter rainy season than Jacó, and it's also easy to see that the driest time to travel to either is January through April.  The dip in rainfall at Jacó (Corcovado doesn't have it) during August is called veranillo (little summer) and occurs each year when the inter-tropical convergence zone (ITCZ) moves north past Costa Rica giving a little dry season in the middle of the rainy season in some places. If you're interested in the details you can read all about how Costa Rica's rainy season occurs.
