Costa Rica is a land of perpetual blue skies, sunny days, and temperate climates. Some researchers have even claimed that the city of Atenas, located in the Alajuela province, has the best climate in the world! Let’s take a closer look at what makes it so special:
Unlike countries with strictly different stations, Costa Rica weather only has two basic seasons: “Green” and “Sunny”. Being a tropical country bordered by two oceans on its sides, Costa Rica has always enjoyed warm weathercheckered by bursts of rain. The temperature in Costa Rica oscillates from mild 90ºs to low 70ºs, but the average is usually around 76ºF. The days begin around 5:30am when the sun rises and come to an end when it sets around 5:30-6:00 pm depending on the time of the year.
The sunny season (or summer) goes from December to March and sometimes includes April. You can expect hot sunny days during these months, however being a tropical country, there is always the chance of an unexpected rain shower.
The Green Season (also known as the Rainy Season) lasts from May to December. Most hotels have special discounts during the Green Season since fewer tourists come to visit. However many activities and tours are planned specially for this unique weather. Sunny mornings and rainy afternoons are the common scenery during this time of the year, giving you the opportunity to enjoy all kinds of outdoor activities during the daytime and then relax to the sounds of the rain later in the day.
Costa Rica is full of microclimates due to its diverse geography, especially the mountain ranges that run through all the country. Higher places often have a cooler temperature and more frequent rains compared to the coastal regions that traditionally have high temperatures and dry lands.
All these microclimates make each region have its own distinct weather patterns. It might be sunny and hot in Manuel Antonioand at the very same time windy and cold in San Jose.
