A decrease in the intensity of trade winds this week will cause an average increase in temperatures of up to 2 degrees Celsius, according to the National Meteorological Institute (IMN).
Costa Rica currently is in the middle of the dry season, which runs from December to May, meaning warmer temperatures are likely during the day, with drastic drops at night.
According to the IMN, average temperatures in the northwestern province of Guanacaste will range from 33-35 degrees Celsius (92-95 Fahrenheit), and 32-34 C (90-93 F) in the Central and South Pacific regions.
Temperatures in the Caribbean region will range from 30-32 C (86-90 F), while the northern region will range from 28-33 C (82-92 F).
In the Central Valley, temperatures will be highest in the western region, ranging from 30-32 C (86-90 F). The eastern region is expected to be slightly cooler, with temperatures ranging from 24-26 C (75-79 F).
The hottest days of the dry season are expected on April 9-18, during the equinox, which causes solar radiation to perpendicularly strike Costa Rica.
Costa Rica’s Social Security System, or Caja, last year reported that six people are diagnosed with skin cancer every day in the country. Global studies indicate that 68 percent of skin cancer occurs on the face, mostly in areas around the lips, eyelids and ears.
Caja officials recommend avoiding long exposure to sunlight, especially from 10 a.m.-2 p.m. They recommend using appropriate clothing to protect the face and arms, as well as sunscreen for anyone planning on being outdoors for an extended period of time.
