December marks the beginning of high tourism season in Costa Rica, and it is easy to understand why. After months of tropical rains, the skies clear, the sun shines brightly, and the entire country seems to come alive with energy, celebration, and color. For both international visitors and Costa Ricans themselves, December is a time of joy, travel, family gatherings, and outdoor living.
From the mild, spring-like climate of the Central Valley to the sun-drenched beaches of the Pacific Coast, December offers some of the best weather of the year. Add to this the festive spirit of Christmas, strong cultural traditions, and a nationwide holiday mood, and you have the perfect recipe for one of the most popular travel months in Costa Rica.
Why December Is High Season in Costa Rica
December officially signals the start of Costa Rica’s dry season, especially in the Central Valley, San José, and along the Pacific Coast. Rainfall decreases dramatically, humidity drops, and days are filled with bright blue skies and comfortable temperatures.
This change in weather comes after roughly six months of rainy season, making December feel like a collective celebration of sunshine. Locals and visitors alike are eager to be outdoors, whether that means heading to the beaches, hiking in national parks, or simply enjoying café life in towns and cities.
For travelers from North America and Europe, December also offers an escape from winter. While snow and cold dominate much of the northern hemisphere, Costa Rica welcomes visitors with warm temperatures, green landscapes, and refreshing ocean breezes.
Ideal Weather Across the Country
One of the most attractive features of December in Costa Rica is the variety of microclimates, all of which become more pleasant during this time of year.
Central Valley and San José
In the Central Valley, including the capital city of San José, December weather is especially comfortable. Days are sunny and warm, while evenings cool off nicely thanks to the higher elevation. Temperatures typically range between the low 70s and high 70s Fahrenheit, making it ideal for sightseeing, cultural activities, and outdoor dining.
Pacific Coast Beaches
The Pacific Coast—particularly the Guanacaste region and the Central Pacific beaches of Jacó and Manuel Antonio—experiences near-perfect conditions in December. Rain is minimal, the ocean is inviting, and sunshine dominates the forecast. This is prime time for beach activities such as swimming, surfing, sunbathing, and snorkeling.
Manuel Antonio, with its stunning combination of rainforest and white-sand beaches, becomes especially popular during this time. Wildlife sightings are common, and visitors can enjoy lush greenery without the heavy rains that sometimes limit access earlier in the year.
A Festive Atmosphere Throughout the Country
December in Costa Rica is not just about the weather—it is also about celebration and tradition. Christmas is taken very seriously, as Costa Rica is a predominantly Christian country with deep Catholic roots.
Homes are decorated with brightly colored lights, and many families proudly display nativity scenes featuring Baby Jesus. Churches are beautifully adorned, and religious symbols are visible throughout towns and neighborhoods.
The holiday spirit is contagious. Streets are lively, shops are busy, and there is a shared sense of joy and anticipation as Christmas approaches.
The Importance of Christmas in Costa Rican Culture
Christianity was introduced to Costa Rica by the Spanish in the early 1500s, and its influence remains strong today. The architecture of many Catholic churches reflects Spanish colonial design, and religious traditions are deeply woven into daily life.
Unlike many countries, there is no separation of church and state in Costa Rica. The Catholic religion is taught in public schools, beginning in elementary education, reinforcing Christian values from a young age.
The most important religious event of the season is Midnight Mass on Christmas Eve, known as Misa de Gallo. Families attend church together to celebrate the birth of Christ, making it one of the most meaningful nights of the year.
After midnight mass, families often return home to share food, conversation, and time together, continuing the celebration into the early hours of Christmas Day.
The “13th Salary” and Holiday Shopping
One of the reasons December feels so lively is the arrival of the 13th salary, known locally as aguinaldo. By law, Costa Rican employees receive this extra month’s pay in December, providing additional income just in time for the holidays.
With extra money to spend, shopping centers, markets, and stores become crowded as people buy gifts, clothing, food, and decorations. The atmosphere is joyful and energetic, filled with laughter, music, and holiday cheer.
This tradition supports not only families but also local businesses, contributing to the overall economic activity during the high tourism season.
Heading to the Beaches After Christmas
Once Christmas Day passes, a national migration begins. Starting around December 26, many Costa Rican families head to the beaches, often staying until early January.
Beach towns fill with both locals and tourists, creating a lively mix of cultures and energy. Families relax by the ocean, children play in the sand, and groups gather for picnics and celebrations.
This period between Christmas and New Year’s is one of the busiest times of the year in coastal areas. Hotels and vacation rentals are often fully booked, and advance planning is essential for travelers visiting during this time.
A Paradise for Tourists Escaping Winter
For international visitors, December in Costa Rica is the perfect antidote to cold, gray winter months back home. Tourists arrive from snowy regions eager to trade coats and boots for sandals and swimsuits.
Beaches are filled with travelers of all ages—couples, families, retirees, and adventure seekers. Some are surfing the Pacific waves, others are lounging by resort pools, while many explore national parks, wildlife refuges, and scenic viewpoints.
The energy is relaxed yet vibrant, blending Costa Rica’s laid-back lifestyle with the excitement of peak travel season.
Outdoor Activities at Their Best
December is one of the best months for outdoor activities in Costa Rica. With dry trails and clear skies, visitors can enjoy:
- Hiking in national parks
- Wildlife watching, including monkeys, sloths, and tropical birds
- Zip lining through the rainforest canopy
- Surfing and snorkeling along the Pacific Coast
- Exploring waterfalls and rivers
Nature is still lush and green from the rainy season, making landscapes especially beautiful and photogenic.
Planning Tips for December Travel
Because December is high season, travelers should plan ahead. Flights, accommodations, and rental cars book quickly, especially during the Christmas and New Year period.
It is recommended to:
- Reserve accommodations several months in advance
- Book tours early to secure availability
- Expect higher prices compared to low season
- Allow extra time for travel, as roads can be busy
Despite the crowds, most visitors agree that the experience is well worth it.
A Season of Beauty, Faith, and Celebration
December in Costa Rica is a time when beautiful weather, cultural traditions, and festive energy come together. It is a season of gratitude, family, and joy, shared by locals and visitors alike.
Whether you are strolling through a sun-filled Central Valley town, attending midnight mass on Christmas Eve, or relaxing on a Pacific beach under clear blue skies, December offers an unforgettable experience.
