Where to Go in Costa Rica in January
Guanacaste & Northwest Pacific
Liberia, Tamarindo, Nosara
A cool, breezy start to the year makes January one of the most pleasant months in Guanacaste; daytime heat is strong but trade winds off the Pacific keep beaches like Tamarindo and Playa Negra comfortable. The dry ground and low humidity mean clear sunsets and easy driving on dirt roads, so it’s peak season for beachside resorts and surf lessons. Pack light cottons, sun protection and a wind layer for evenings in Liberia.
Nicoya Peninsula & Northern Central Pacific
Santa Teresa, Montezuma, Nicoya
A bright, dusty start to the year characterizes January on the Nicoya Peninsula, with strong sun at beaches like Santa Teresa and long dry stretches that are perfect for surfing and yoga retreats. Seas are usually calm for snorkeling at Cambutal and horseback rides along the shore are easy; evenings cool modestly. This is high season - book surf lessons and ferries early and pack reef-safe sunscreen and light layers for chillier nights near the hills.
Central Pacific
Manuel Antonio, Jaco, Puntarenas
A crisp, sunny beginning to the year makes January excellent for visiting Manuel Antonio National Park and nearby beaches; humidity is low and wildlife is easier to spot along dryer forest trails. Ocean conditions are generally calm for snorkeling around Marino Ballena though boat operators fill up fast. Pack light layers for coastal evenings and expect high-season crowds and higher rates in Jaco and Manuel Antonio.
Southern Pacific & Osa Peninsula
Uvita, Dominical, Corcovado
A warm start to the year sees January drier than the central and southern wet-season months, but the Osa Peninsula retains a humid, jungle feel year-round; mornings are usually still manageable for Corcovado park treks. Wildlife viewing along trails and estuaries can be excellent as bridges and paths are easier to cross, though some remote access roads remain sandy. Pack breathable layers, bug spray and book guided tours early - lodges are busier during the dry-window months.
Central Valley & Highlands
San José, Alajuela, Cartago, Poás, Arenal, Monteverde
A cool, pleasant start to January in the Central Valley brings dry, sunny days around San José and Alajuela with mild nights - ideal for city sightseeing, coffee tours and walks in La Sabana. Higher-altitude spots like Poás and Monteverde are cooler and misty in the mornings; bring a light jacket. This is a popular month for visitors to combine cultural trips with short volcano excursions, so reserve day tours and expect clearer crater views.
Caribbean Coast
Puerto Viejo, Cahuita, Tortuguero
A humid, tropical beginning to January on the Caribbean coast brings warm sea breezes and frequent short rain showers that can fall at any time; it’s not a reliably dry month like the Pacific’s high season. Beaches in Puerto Viejo are lively and turtle programs at Tortuguero may still run, but expect intermittent rain-driven closures for some small boat trips. Bring mosquito repellent, a light rain jacket, and embrace the region’s lush, humid atmosphere.
Events & Festivals in January
Fiestas de Palmares
