Seasonal Climate and Temperature Ranges

Costa Rica’s tropical climate means warm weather year-round. Even in the coolest months, temperatures average in the 70s°F across most of the country. Along the scenic coastlines, daily highs often reach the 80s and 90s°F, while higher inland elevations see slightly cooler weather, especially at night. Sweater weather is rare—even at Costa Rica’s peak elevations.

The year is divided between two seasons:

• Dry Season (Verano):
  From December to April, the dry season offers little rain, lower humidity, and plenty of sunshine. Visitors can enjoy rain-free beach days and abundant sun, though some inland areas may experience occasional light showers.
• Wet Season (Invierno):

Expect brief or prolonged rains, especially in the afternoon and evening, while mornings typically remain clear. Although humidity increases and temperatures may feel warmer, the rains nourish Costa Rica’s lush jungles and cascading waterfalls.

Explore the questions below to learn more about how Costa Rica’s unique weather patterns can impact your travel plans and daily life.

When is the best time to visit Costa Rica for ideal weather?

Costa Rica experiences two distinct seasons: the dry season (December through April) and the wet season (May through November). Many travelers find that the dry season offers ideal conditions for outdoor activities, sightseeing, and beach visits due to clear skies and lower humidity. However, the wet season also has its appeal—with fewer tourists, vibrant green landscapes, and often lower prices. Ultimately, the best time to visit depends on your activity preferences and tolerance for occasional rain showers.

What is the average temperature in Costa Rica?

Costa Rica enjoys a warm, tropical climate with temperatures that remain relatively consistent throughout the year. In general, you can expect average daytime temperatures to range between 80°F and 90°F (27°C to 32°C) along the coast, where the sun shines brightly most days. Inland areas and higher elevations, such as those around San José or in the Central Valley, tend to be a few degrees cooler, especially during the evenings and early mornings, with averages closer to 70°F to 80°F (21°C to 27°C). This mild variation is one of the reasons Costa Rica is such a popular destination year-round—most regions offer comfortable weather no matter when you visit.

What is the rainy season in Costa Rica?

The rainy season in Costa Rica, also known as the “green season,” typically runs from May to November, with the heaviest rainfall occurring from September to November.

How much rainfall does Costa Rica receive annually?

Rainfall in Costa Rica varies considerably by region and season. On average, coastal areas, particularly on the Pacific side, can receive between 1,000 and 3,000 millimeters (39 to 118 inches) of rain each year. In contrast, the Caribbean coast tends to be wetter throughout the year. The bulk of the rainfall occurs during the wet season, typically in short, intense bursts during the afternoons or evenings, which helps maintain the country’s lush vegetation and rich biodiversity.

What should I pack for a trip to Costa Rica given its weather?

Packing for Costa Rica requires preparation for a range of weather conditions. During the dry season, lightweight clothing, swimwear, and sun protection are essential for enjoying the sun and beaches. For the wet season, be sure to include a waterproof jacket, quick-dry clothing, and sturdy footwear for rainy days and potential muddy trails. Additionally, if you plan to visit higher-altitude areas or cooler inland regions, consider packing a light sweater or layer. This way, you’ll be prepared for both the heat of the coast and the cooler temperatures found elsewhere.

Does the weather vary significantly across different regions of Costa Rica?

Yes, Costa Rica is known for its diverse microclimates. The weather can vary dramatically between regions: the Pacific coast generally enjoys abundant sunshine and drier conditions during the dry season, while inland areas, particularly in the Central Valley, experience cooler temperatures, especially at night. The Caribbean coast has a more consistent rainfall pattern year-round. This variability allows visitors to experience a range of climates—from warm, tropical beaches to cooler, misty highland regions—all in one trip.

Does Costa Rica experience extreme weather events such as hurricanes or tropical storms?

Costa Rica is relatively sheltered from the most extreme weather events. Hurricanes are rare in this region, thanks to its position in Central America and the influence of surrounding ocean currents. However, during the wet season, Costa Rica can experience intense tropical downpours, localized flooding, and strong winds. Travelers should stay informed through local weather alerts, especially if planning activities in coastal or low-lying areas.

How does altitude affect the weather in Costa Rica?

Altitude plays a key role in shaping Costa Rica’s climate. Coastal and lowland areas typically experience warmer temperatures and higher humidity, while higher elevations, such as those in the Central Valley or mountainous regions, are cooler and can see significant temperature drops at night. This variation means that you might enjoy warm, tropical weather on the beaches while experiencing more temperate conditions inland, so packing layers is advisable.
