Weather in Costa Rica in January

January brings a refreshing shift in weather across Costa Rica, offering a variety of climates depending on where you go.

Pacific Coast

On the Pacific side of Costa Rica, January is nothing short of glorious. From Guanacaste down to the Osa Peninsula, the skies are bright, the humidity drops, and the sun shines nearly every day. With daytime temperatures hovering around 90°F (32°C) it’s the perfect time to hit the beach, explore national parks, or simply bask in the warmth of the dry season.

Caribbean Coast

Over on the Caribbean Coast, however, the story is a bit different. January often brings brief showers and the occasional thunderstorm, especially in places like Puerto Viejo and Tortuguero. While the rain can linger throughout the day, it also keeps the landscape lush and vibrant. Those who don’t mind a little weather will still find plenty to enjoy, especially with fewer crowds and a more laid-back atmosphere.

Central Valley

In the Central Valley, including areas like San Jose, Arenal, and Monteverde, January offers a comfortable and balanced climate. Expect mild days in the high 70s°F (25°C) with minimal rainfall, crisp mornings, and cool nights. Occasional light showers may drift in during the evenings, but overall, this region enjoys some of the most pleasant and consistent weather in the country this time of year.

Regional Highlights in January

From sun-drenched beaches to misty mountains, Costa Rica’s regions each offer something special in January.

La Fortuna & Arenal: Tucked at the base of one of the country’s most iconic volcanoes, Arenal Volcano, La Fortuna is a hotspot for travelers in January. The skies are usually clear, making it the perfect time to hike lava trails, zipline through rainforests, and soak in thermal hot springs under the stars. The surrounding greenery, left vibrant from the last of the rains, makes the scenery pop even more, volcano views included.

Manuel Antonio & the Central Pacific: For a mix of wildlife, beaches, and breathtaking viewpoints, Manuel Antonio National Park shines in January. The dry weather makes it easy to hike the trails, spot sloths and monkeys, and swim in turquoise bays without worrying about mud or downpours. It’s a popular destination this time of year, but the charm of the region and the beauty of the coast make the crowds worth it.

Osa Peninsula: If you’re looking for something more remote, the Osa Peninsula is a hidden treasure. Home to Corcovado National Park (often referred to as the most biodiverse place on Earth) it’s a wild wonderland of jaguars, toucans, and unspoiled rainforests. The trails are drier this time of year, but the region still feels off-the-grid and untouched, ideal for adventurers and eco-travelers alike.

Top Activities in Costa Rica in January

With sunny skies and hardly any rain, January is one of the best times to escape winter and get outside to enjoy Costa Rica’s natural beauty.

Hiking: From the rugged trails of Rincon de la Vieja to the lush paths of Arenal, January is one of the best months to go hiking in Costa Rica. With minimal rain and plenty of daylight, even longer hikes become more accessible. Trails are dry and wildlife is active (especially in the early mornings) so it’s a great time to lace up your boots and explore everything from volcanic landscapes to cloud forests.

Zip Lining & Canopy Tours: Soaring above the treetops is one of Costa Rica’s signature thrills, and January’s stable weather makes it even more exhilarating. Glide through the forest canopy in Monteverde or along the Pacific coast with sweeping views of jungle and sea. The cooler temperatures in the mountains also make this adrenaline-pumping activity surprisingly refreshing.

Surfing: January brings near-perfect surf conditions to Costa Rica’s Pacific coast. The northern beaches like Tamarindo and Playa Flamingo offer consistent swells, sunny skies, and warm waters, ideal for both beginners and experienced surfers. And if you’re new to the sport, surf schools are in full swing, ready to help you catch your first wave under that glorious tropical sun.
