This region also includes Puntarenas town, Jaco, Quepos, Manuel Antonio and Parrita.
Because of its location and its inclusion of coastal areas and mountains (up to 6,167 feet above sea level), this weather region has less continuity in climate than other parts of the country. Along the coast, average rainfall is 143 inches per year, but as you ascend into the mountains up to 2,500 feet above sea level, the rainfall almost doubles to 262 inches per year.
The dry season in this region lasts from January to March, with February being the driest month. The rest of the year is technically the wet season, October being the rainiest. There are typically five hours of sun during the rainy months, and eight hours of sun from January to April. The days begin sunny with clouds moving in during the early afternoon and rain during the afternoon and/or night.
The average temperature is 81 degrees on the coast and 63 degrees in the mountains. Average day time temperatures along the coast are at their highest between January and May, reaching 90 degrees, and generally, temperatures never drop below 71degrees at night. While in the mountains the temperature can drop to 48 degrees.
The relative humidity is consistently at 85 percent. During January and February, it drops to between 75 and 80 percent humidity, and reaches its peak of 90 percent humidity in June, September and November. Winds from the south dominate the days, while the nights are usually calm with slight breezes from the east.
