Climate in Costa Rica
Costa Rica has a tropical climate with two main seasons. The dry season runs from December to April, and the rainy season from May to November, with temperatures remaining fairly consistent throughout the year. On the coast, temperatures average between 27°C (81°F) and 32°C (89°F), often cooled by sea breezes; the highlands are milder, with warm days and cooler nights.
Rain is heaviest in September and October, while the dry season brings clear skies and minimal rainfall, making it the most popular time for tourism. However, the rainy season, often called the 'green season', offers lush landscapes, fewer crowds and lower prices. Mornings during this time are typically sunny, with showers in the afternoon.
There's no winter in Costa Rica, and sunshine is common year-round, making it a reliable destination at any time. For those looking to avoid peak crowds, visiting in the shoulder months of May or late November is a great option.
