The average temperature hovers around 25 °C (77 °F) in Costa Rica, yet this can fluctuate depending on altitude. Lowlands tend to be warmer and more humid, while the highlands offer cooler and drier conditions, contributing to the country's climatic diversity.
Here's a refined description of the climate in different regions of Costa Rica:
Caribbean Coast: The Caribbean coast boasts a consistently hot and humid climate, maintaining temperatures between 25 - 32 °C (77 - 90 °F) throughout the year. Notably, this region experiences an intense wet season with an annual rainfall averaging over 4,000 mm (160 in).
Pacific Coast: Contrasting with the Caribbean, the Pacific Coast enjoys a more temperate climate, with temperatures ranging from 22 - 28 °C (72 - 82 °F). The wet season here is less intense, marked by an annual rainfall averaging around 1,500 mm (60 in).
Central Valley: Nestled between the Caribbean and Pacific coasts, the Central Valley features a mild climate year-round, with temperatures ranging from 18 - 25 °C (64 - 77 °F). The wet season is more temperate than the coastal regions, with yearly rainfall averaging around 1,000 mm (40 in).
Highlands: Located in the north and south, the highlands offer a cooler climate than the lowlands. Nighttime temperatures can drop below freezing, especially during the dry season, contrasting the warmer coastal regions.
Costa Rica's dynamic geological landscape is marked by a notable prevalence of dormant and active volcanoes scattered across its terrain. This volcanic activity is intricately linked to the country's location along the Pacific Ring of Fire, an expansive horseshoe-shaped zone renowned for its heightened seismic and volcanic activity.
Positioned on the Caribbean Plate, Costa Rica shares its borders with the Cocos Plate in the Pacific Ocean, a plate being subducted beneath it. This subduction process is instrumental in shaping the volcanic features that define Costa Rica's topography. The subduction of the Cocos Plate beneath the Caribbean Plate creates intense geological activity, giving rise to the formation of the country's volcanoes, which collectively constitute the Central America Volcanic Arc.
The Central America Volcanic Arc is a chain of volcanoes extending from Guatemala to Panama, with Costa Rica nestled in the heart of this volcanic belt. The subduction-driven volcanic activity manifests in various forms, ranging from majestic stratovolcanoes to volcanic fields, each contributing to the country's captivating and diverse landscape.
This geological phenomenon not only shapes the physical characteristics of Costa Rica but also plays a crucial role in the country's ecosystem and biodiversity. Volcanic soils, enriched with minerals and nutrients, contribute to the fertility of the surrounding areas, fostering lush vegetation and supporting diverse flora and fauna.
