What is the humidity year-round in Costa Rica? Is the central valley drier than the coast?

Hi Aaron,
While Costa Rica does generally have a high level of humidity, it’s also host to a number of microclimates, so the humidity level varies significantly from place to place.
The range of volcanoes that form Costa Rica’s “spine” serve to block and disrupt airflow patterns. When moisture-heavy winds roll in from the northeast, they dump water when they meet the mountainous impasse. This means the Caribbean side of the country generally has a shorter “dry” season.
The region of Guanacaste, along the north Pacific coast, sees the least rainfall in Costa Rica, but also features some of the hottest temperatures in the country, with averages ranging from 80 F to 90 F.
The Central Valley, much like the rest of Costa Rica, is subject to the clearly defined “wet” and “dry” seasons, with a more comfortable, Spring-like climate year-round, as opposed to the raw heat you’ll find on the coastline. Due to its elevation, ranging anywhere from 3000-5000 feet, temperatures hover around the mid-70s F, sometimes getting up to the low 80s F. The Central Valley’s dry season generally begins in December and lasts until mid-April.
Because of Costa Rica’s varying microclimates, the best piece of advice is to try out a place before you decide to settle there. Start with the coastal beaches on either side of the country. Get a feeling for the hot, humid oceanic air, with balmy ocean breezes at night that allow veranda dining and a good night’s sleep.
Then, perhaps, move to mid-elevation towns where the days will be in the invigorating middle- to high-70s F. In the mountainous areas, you’ll experience the most comfortable climate and enjoy the lush green vistas of Costa Rica.
