Tropical Rainforest Climate
Costa Rica’s tropical rainforest climate is primarily found along the Caribbean coast. Here, you can expect high humidity and significant rainfall throughout the year. This area is lush and green, thanks to the constant supply of rain.
Regions like Corcovado National Park and Tortuguero National Park are perfect examples of this climate zone. These areas are home to a vast array of wildlife, including howler monkeys, sloths, and colorful birds.
