Costa Rica Season and Weather Information
There are only two seasons in Costa Rica, wet and dry. The wet season generally runs from May to November and is characterized by tropical showers with variable winds. The rainiest months are September and October with torrential downpours often washing out roads and riverbeds.
The dry season, December to April, brings consistent offshore winds and the coolest weather despite little to no rainfall. Water temps average 80 degrees year round.Costa Rica is a good bet for surf any time of year. The Southern Pacific Ocean vibrates energy toward Costa Rica’s Pacific coast year-round, although south swells are strongest from April thru September. The northernmost part of Guanacaste from Tamarindo to Nicaragua sticks out like an elbow and is exposed to winter swells from November to April. Northern Costa Rica also benefits from Nicaragua’s Lake Effect offshore winds that can blow all day, every day. Which is why you so often see photos of Witch’s Rock and Ollie’s Point offshore and firing.
