Costa Rica Weather Overview
Known for its stunning beaches, lush rainforests, and incredible biodiversity, Costa Rica is a top destination for travelers seeking a tropical escape. Its location near the equator and along Central American coastlines creates two distinct seasons – dry and wet. Understanding Costa Rica’s weather will help you pack properly and plan activities that match the conditions during your stay.
Seasonal Climate and Temperature Ranges
Costa Rica’s tropical climate means warm weather year-round. Even in the coolest months, temperatures average in the 70s°F across most of the country. Along the scenic coastlines, daily highs often reach the 80s and 90s°F, while higher inland elevations see slightly cooler weather, especially at night. Sweater weather is rare—even at Costa Rica’s peak elevations.
The year is divided between two seasons:
-
Dry Season (Verano):
From December to April, the dry season offers little rain, lower humidity, and plenty of sunshine. Visitors can enjoy rain-free beach days and abundant sun, though some inland areas may experience occasional light showers. -
Wet Season (Invierno):
From May through November, tropical downpours become frequent as the landscape transforms into vibrant greenery. Expect brief or prolonged rains, especially in the afternoon and evening, while mornings typically remain clear. Although humidity increases and temperatures may feel warmer, the rains nourish Costa Rica’s lush jungles and cascading waterfalls.
