Costa Rica, a country located in Central America, is known for its rich biodiversity and varied climate. The country's weather patterns are influenced by its geography, with the Central Highlands and coastal regions experiencing different conditions throughout the year. Understanding the weather patterns in Costa Rica is essential for planning a trip or relocating to this beautiful country. In this article, we will explore the Costa Rica weather by month, highlighting the average temperatures, precipitation, and other factors that affect the climate.
Introduction to Costa Rica’s Climate
Costa Rica’s climate is generally divided into two main seasons: the dry season (December to April) and the rainy season (May to November). The dry season is characterized by minimal rainfall and plenty of sunshine, making it the peak tourist season. The rainy season, on the other hand, is marked by increased precipitation and higher humidity. However, the country’s diverse geography means that different regions experience different weather patterns, even within the same season.
Regional Climate Variations
Costa Rica can be broadly divided into four main regions: the Central Highlands, the Pacific Coast, the Caribbean Coast, and the Northern Plains. Each region has its unique climate characteristics. The Central Highlands, which include the capital city San José, experience a mild climate with average temperatures ranging from 15°C to 25°C (59°F to 77°F). The Pacific Coast, which is home to popular tourist destinations like Tamarindo and Puerto Viejo, has a tropical dry climate with high temperatures and minimal rainfall during the dry season. The Caribbean Coast, which includes the province of Limón, has a tropical wet climate with high precipitation throughout the year. The Northern Plains, which include the Arenal Volcano region, have a tropical savanna climate with distinct wet and dry seasons.
