CLIMATE
There are two clearly defined seasons in Costa Rica: the dry and the wet seasons. For San José and the western littoral, the "summer" or dry season goes from December to April; while in the province of Limón, on the Caribbean, it occurs from February to April. The rains come from May through November for most of the country. This usually consists of a couple of hours of rain in the afternoon or early evening, leaving a clear day for the most part.
Yet, the temperature changes throughout the year are not drastically varied at any given location, instead there is a tremendous variation from place to place because of the rugged terrain involved in the country’s geography. Temperatures in the highlands range from 10 – 13 degrees Celsius (50 – 55 degrees Fahrenheit), while in the Central Valley they average 22 degrees Celsius (72 degrees Fahrenheit) and 26 degrees Celsius (80 degrees Fahrenheit) at sea level.
SUN
Being 8 to 10 degrees from the equator presents a much more serious risk for acquiring a flaming sunburn than further up the Northern Hemisphere. Take precautions and use a hat or effective sunscreen when exposed to the sun’s rays. The importance of this cannot be over-emphasized. The concern is greater when you are at the beach or in the ocean since salt and water are ideal reflectors.
