Costa Rica’s Climate and Weather Patterns
Dry Season (Verano): December to April
Characteristics: This period is the peak tourist season due to the generally pleasant weather, with less rainfall and abundant sunshine. The skies are usually clear, and temperatures are warm.
Advantages: Ideal for outdoor activities like hiking, beach lounging, and exploring national parks. Wildlife is more visible as animals gather near water sources.
Rainy Season (Invierno): May to November
Characteristics: Marked by more frequent rainfall, especially in the afternoons and evenings. Despite the name, rain typically comes in short, intense bursts followed by sunshine.
Advantages: The rainy season brings lush, green landscapes, perfect for nature lovers and photographers. Accommodation and tour prices are often lower, and there are fewer tourists.
Considerations: Some activities might be limited or disrupted due to the weather, and certain roads in remote areas can become challenging to navigate.
Central Valley Climate
The Central Valley, home to the capital city of San José, enjoys a mild climate with temperatures averaging around 70°F (21°C) year-round. Its higher elevation means it can be cooler than coastal areas, especially at night.
Caribbean vs. Pacific Coasts
Caribbean Coast: Experiences a more consistent rainfall pattern throughout the year, with the heaviest rain between September and October, contributing to the region's lush rainforests and vibrant vegetation.
Pacific Coast: Exhibits regional variations. The northern Pacific (Guanacaste) is drier with less overall rainfall, making it a popular destination during the dry season. The central and southern Pacific areas receive more rainfall during the rainy season.
Mountain Areas
Mountainous regions like the Monteverde Cloud Forest and the Arenal Volcano area can have cooler temperatures due to their elevation, with mist and fog common in cloud forests.
Hurricane Season
While Costa Rica is located south of the typical hurricane path in the Caribbean, there is still a potential risk of heavy rainfall and storm effects, particularly along the Caribbean coast, during the Atlantic hurricane season (June to November).
