Understanding Costa Rica’s Climate
Costa Rica’s climate is predominantly tropical, with two main seasons: dry and rainy. The dry season, known locally as verano (Summer), runs from December to April. In contrast, the rainy season, invierno (Winter), extends from May to November.
However, don’t be fooled into thinking the climate is uniform across this small nation. Costa Rica’s varied topography creates a multitude of microclimates. Mountains, plains, coastlines, and forests each have distinct weather patterns.
Here’s a basic rundown of what to expect:
- Dry Season (Verano): December to April
- Rainy Season (Invierno): May to November
- Mid-year Dry Spell: Occurs in June or July
Temperatures in Costa Rica remain fairly stable throughout the year. Coastal areas are warmer, while highland areas like San José are cooler. December and January offer cooler temps, whereas March and April ramp up the heat.
Rainfall is the primary variable, impacting not just travel plans but also flora and fauna. Higher elevations and Caribbean regions often receive more rain throughout the year. Understanding these variations will enhance your Costa Rica adventure planning.
January: New Year, New Adventures
January in Costa Rica is nothing short of delightful. It is one of the driest months of the year, making it perfect for exploring. With temperatures ranging from the mid-60s to high 80s Fahrenheit (18-31°C), you can enjoy both beaches and highlands comfortably.
The sun shines brightly, and the air is fresh, inviting outdoor activities. Wildlife viewing, particularly bird watching, is at its peak. Travelers flock to the beaches, national parks, and mountains, eager to escape colder northern climates. It’s a lively time. The festive spirit of the New Year is in the air, making your travel experience better.
February: Sun-Soaked Days
As February rolls in, Costa Rica continues to bask in the warmth of the dry season. The weather remains consistently sunny, making it an ideal time for outdoor enthusiasts. With little to no rain, beaches become a major attraction, drawing sun-seekers from around the world.
Temperatures during February hover pleasantly, encouraging adventures from coast to inland regions. Whether it’s surfing in Tamarindo or hiking in the Central Valley, activities abound. The dry landscape may lack lushness, but it compensates with the ease of exploration. An air of relaxation permeates the country, perfect for those chasing sunshine and adventure.
March: The Heat Picks Up
March in Costa Rica signals rising temperatures as it nears the end of the dry season. The heat intensifies, especially in regions like Guanacaste and the Pacific coast. Visitors can expect hotter days, with temperatures occasionally nudging the higher end of the spectrum.
Despite the heat, it’s a great time for beach outings and water sports. Inland, cooler areas like Monteverde provide a comfortable escape. While rain remains scarce, the increasing warmth hints at the upcoming seasonal change. Adventure seekers should pack light and hydrate well, embracing the sunny adventures March has to offer.
April: Last Call for Dry Season
April marks the final stretch of Costa Rica’s dry season. It’s a month where the sun still dominates, but the atmosphere hints of the impending rains. Days can feel quite hot, especially in areas like the Nicoya Peninsula.
This month is perfect for indulging in outdoor fun, from hiking to beach basking, before the rains arrive. As the end of April approaches, sporadic showers may start making brief appearances. This slight shift offers a refreshing break from the heat, keeping the landscape vibrant and ready for the wetter months ahead.
May: Transition to Green
May signals the start of Costa Rica’s rainy season, also known as invierno. The first showers make their presence felt, transforming the dry landscape into lush shades of green. This month often brings afternoon rainstorms, while mornings remain sunny.
Although the weather begins to shift, May offers a balanced climate ideal for experiencing the country’s natural beauty. It’s a great time for exploring rainforests as the moisture breathes new life into the ecosystem. Wildlife becomes more active, and landscapes bloom with vibrant flora, making it a photographer’s dream. The transition month sets the stage for more persistent rains in the coming months.
June & July: Mid-Year Dry Spell
In June and July, Costa Rica experiences a brief respite from the rainy season. Known locally as the “veranillo” or little summer, this mini dry season offers travelers an excellent opportunity to enjoy the outdoors. The weather is typically warm, with fewer afternoon rain showers than May.
This period is perfect for visiting Costa Rica’s pristine beaches and indulging in water activities. Visitors can explore rainforests without worrying about heavy downpours, making this an attractive time for ecotourism. The moderate weather conditions attract both locals and tourists alike, offering a unique window of pleasant weather amidst the otherwise rainy months.

This month sees lush landscapes come alive with vibrant colors. It’s a fantastic time for photographers and nature enthusiasts. While some regions may experience increased humidity, the rich biodiversity compensates with spectacular wildlife sightings. Prepare for sudden weather changes, and embrace the humid climate as part of Costa Rica’s tropical charm.
September & October: Peak of the Rainy Season
September and October are the heart of Costa Rica’s rainy season. Daily rains become a reliable occurrence, often in the afternoons. This is the ideal time to experience the country’s impressive waterfalls and lush forests.
Travelers should pack for wet conditions, as trails can be muddy and some roads less accessible. Despite the rainfall, the vibrant greenery and thriving wildlife make it worth braving the wet season. These months offer a more secluded experience, as fewer tourists visit during this time. Moreover, reduced tourist crowds can result in better deals on accommodations and tours.
November: A Gradual Return to Dry Weather

With the landscape still lush from the recent rains, it’s an excellent time for nature exploration. The gradual drying trend allows for improved road conditions, making travel easier.
