The Climate: An Overview
Trip Planning - About Costa Rica


It's Always Fair Weather

Costa Rica's location between eight and eleven degrees north of equator suggests that the weather is the same year round. Not so. The country's mountainous landscape provides a cooler climate in regions of higher elevation. At sea level, travelers will delight in the tropical rainforests and balmy beaches running along both coasts.

Costa Rica's climate is marked by two distinct seasons:

The Wet Season drizzles along from May to the middle of November, bringing sunny, summery mornings, splashed by bouts of warm afternoon rain. The wet season is punctuated by a "little summer" (el veranillo), a short dry season that occurs in July and August. In September and October, look for Los Torrenciales, dramatic downpours that drench the hillsides and fill the rivers to the top. If you plan to drive the back roads during these months, bring your 4 x4 and a sandwich. You may be stuck back there for a while.

The Dry Season begins in the end of November and continues through April. Dry, warm and sunny days march past in endless procession, tempered in January and February by winds cooled by the two seas.

The warmest months are March, April and May, coinciding with the end of the dry season.  The coolest temperatures are found from November through January and are mostly due to the mild northeasterly trade winds, known as “Alisios”, which flow through the mountains. As a general rule, there are greater temperature variations between the days and nights (as much as 14°F to 18°F (8°C to 10°C)) than there are between the seasons.   The average temperature throughout the year in Costa Rica is between 22°C and 27°C (71°F and 81°F).

The cognoscenti – experienced travelers – schedule their visits between the middle of November and the end of March. Many tourists skedaddle around Easter time, but drift back in June and July to play on the beaches in the morning, and sit in the window with a book and a tonic through the afternoons of warm rain.

Trip Planning Alert: If you choose to visit Costa Rica during the high season (December - April), schedule everything well in advance. It is also helpful, and often required,  to make a deposit (by credit card) for your reservations. Bring along a faxed confirmation of your reservations as a hedge against unhappy confusion.

Bargain-conscious travelers prefer to visit Costa Rica in November, or April and May (right after Easter). Rates will be lower and discounts available on practically everything.
