Costa Rica Weather: What to Expect Year-Round

Costa Rica is a tropical paradise known for its lush rainforests, stunning beaches, and incredible biodiversity. But if you’re planning a trip to this Central American gem, you’ll want to know what to expect from the weather year-round. This guide provides an in-depth look at Costa Rica’s climate, including seasonal variations, average temperatures, and rainfall patterns, to help you plan your perfect vacation.

Costa Rica’s Climate Overview

Costa Rica is located just north of the equator, which means it has a tropical climate. This results in warm temperatures and high humidity throughout the year. However, the country boasts a variety of microclimates due to its diverse geography, which includes coastal areas, mountains, and rainforests.

Dry Season vs. Rainy Season

The weather in Costa Rica is generally divided into two main seasons: the dry season, known locally as verano (summer), and the rainy season, referred to as invierno (winter). Understanding these seasons is crucial for planning your trip:

Dry Season (December to April)

The dry season is the most popular time for tourists to visit Costa Rica. During this period, you can expect:

  • Plenty of sunshine and clear skies
  • Less humidity compared to the rainy season
  • Average temperatures ranging from 70°F (21°C) to 90°F (32°C)
  • Minimal rainfall, especially in the Pacific coastal regions

This is the ideal time for beach activities, hiking, and exploring the country’s natural beauty without the worry of heavy rain.

Rainy Season (May to November)

The rainy season, also known as the green season, is characterized by:

  • Frequent afternoon showers and thunderstorms
  • Higher humidity levels
  • Average temperatures ranging from 70°F (21°C) to 85°F (29°C)
  • Lush, vibrant landscapes due to increased rainfall

While the rainy season may deter some travelers, it offers a unique opportunity to experience Costa Rica’s rainforests in their full glory. Plus, it’s the perfect time to enjoy fewer crowds and lower accommodation rates.

Regional Weather Variations

Costa Rica’s diverse geography means that weather can vary significantly from one region to another. Here’s a breakdown of what to expect in different parts of the country:

Pacific Coast

The Pacific coast is divided into three main regions: the North Pacific, Central Pacific, and South Pacific. Each area experiences slightly different weather patterns:

North Pacific (Guanacaste)

The North Pacific region is known for its dry, sunny weather, especially during the dry season. This area receives the least amount of rainfall in the country, making it a popular destination for beachgoers. Average temperatures range from 75°F (24°C) to 95°F (35°C) during the dry season.

Central Pacific (Puntarenas)

The Central Pacific region experiences a mix of dry and rainy weather. While the dry season offers plenty of sunshine, the rainy season brings afternoon showers that rejuvenate the lush rainforests. Temperatures typically range from 75°F (24°C) to 90°F (32°C).

South Pacific (Osa Peninsula)

The South Pacific region is one of the wettest areas in Costa Rica, especially during the rainy season. This region receives heavy rainfall, contributing to its rich biodiversity. Temperatures range from 70°F (21°C) to 85°F (29°C).
