Weather in Costa Rica
Costa Rica is divided in half by an alpine spine through the middle of the country. The Pacific side has dry forests while the Caribbean side has wet, humid forests. Like the country's natural regions, the year is divided into two, with a rainy and dry season.
The rainy season lasts from May to November and temperatures remain above 70°F (20°C), except in the mountains where it may drop to 40°F (4°C) and occasionally below freezing. Expect plenty of rain, especially when there is a hurricane somewhere else in the Caribbean.
The dry season lasts from December to April and is the most popular tourist season. The days stay above 70°F (20°C) and reach 90°F (30°C) on a very hot day, especially at the coast, while the alpine areas hover between 40-50°F (5-10°C).
Unlike many other countries on the Caribbean Sea, Costa Rica is at little risk of hurricanes. Earthquakes and volcanic activity are more pressing environmental hazards and, while rare, have resulted in fatalities in recent years. Expats should therefore make sure they are up-to-date and well informed about the risk of natural disasters in Costa Rica.
