Costa Rica Weather in February: The Best Month to Visit?

February is notable for being Costa Rica's driest month nationally, with rainfall at its annual minimum on the Pacific coast. Guanacaste—the primary beach destination—receives a statistical average of just 0.1–0.5 inches (3–13 mm) of rain for the entire month of February. This translates to weeks of uninterrupted sunshine at destinations like Tamarindo, Playa Flamingo, Playa Conchal, and the Papagayo Peninsula.

The trade winds that define the dry season are consistent in February, blowing from the northeast and sweeping skies clear of clouds. These winds reduce humidity significantly from the rainy season peaks of 80–90%. In February, coastal relative humidity drops to 55–70%, making the warm temperatures feel considerably more comfortable than the same temperatures during the wet season.

February also stands out because the Caribbean coast begins its own drier period simultaneously. From approximately February through April, Puerto Viejo and Cahuita receive reduced rainfall compared to December and January. This convergence—Pacific and Caribbean both in favorable conditions—makes February the one month when travelers have the most flexibility in choosing which coast to visit.

Guanacaste (Tamarindo, Flamingo, Conchal, Nosara, Sámara): Average high 88–92°F (31–33°C). Average low 72–75°F (22–24°C). Sea temperature 80–82°F (27–28°C). Trade winds provide comfortable cooling. Minimal to zero rainfall.

Central Pacific (Jacó, Manuel Antonio, Quepos): Average high 85–88°F (29–31°C). Average low 72–74°F (22–23°C). Rainfall 1–2 inches (25–51 mm). Sunny, with the rare afternoon shower possible.

Southern Pacific (Dominical, Uvita, Osa Peninsula): Average high 84–87°F (29–31°C). Average low 72–74°F (22–23°C). Rainfall 2–4 inches (51–102 mm). Driest period of the year for this wetter region.

San José and Central Valley: Average high 78–80°F (26–27°C). Average low 62–64°F (17–18°C). Rainfall 0.2 inches (5 mm). One of the clearest months in the capital.

La Fortuna and Arenal area: Average high 81–83°F (27–28°C). Average low 68–70°F (20–21°C). Rainfall 3–4 inches (76–102 mm). Driest of the wet-climate zones. Best month for volcano views.

Monteverde Cloud Forest: Average high 68–70°F (20–21°C). Average low 56–58°F (13–14°C). Rainfall 1.5–2 inches (38–51 mm). Windy season. Cool and sometimes misty.

Caribbean Coast (Puerto Viejo, Cahuita): Average high 82–84°F (28–29°C). Average low 72–74°F (22–23°C). Rainfall 5–8 inches (127–203 mm). Beginning of Caribbean drier period. Good snorkeling at Cahuita reef.

Costa Rica's Pacific coast is at its spectacular best in February. The combination of dry conditions, warm water, reduced humidity, and trade wind breezes creates ideal conditions for virtually every beach and water activity. Ocean visibility for snorkeling and diving reaches its annual peak in February—15–40 feet (5–12 meters) at good sites on both coasts.

Swimming is excellent at protected beaches throughout Guanacaste and the Central Pacific. The gentlest swimming beaches include Playa Sámara, Playa Carrillo, Playa Conchal, and the main beach at Manuel Antonio. More exposed beaches can have currents; always swim at beaches with lifeguards or with local knowledge about conditions.

Catamaran tours, sailing, snorkeling excursions, kayaking, and stand-up paddleboarding are all at their best in February's calm Pacific conditions. Full-day boat tours to Isla Tortuga (off the southern Nicoya Peninsula) or Isla del Caño (near the Osa Peninsula) are highly recommended in February for their outstanding water clarity and marine life.

February begins the Caribbean coast's best weather window. Puerto Viejo, Cahuita, and the surrounding Talamanca coast shift into a relative dry period that persists through April. Rainfall drops to 5–8 inches (127–203 mm) in February—significantly less than December's 15–20 inches. The seas calm and clear, making snorkeling at Cahuita National Park's reef particularly rewarding.

Cahuita National Park is one of the top February destinations for travelers who include the Caribbean in their itinerary. The park's coral reef—one of Costa Rica's most important marine ecosystems—is accessible by snorkeling from the park's beaches in February when conditions are at their calmest. The terrestrial side of the park offers sloths, monkeys, butterflies, and an extraordinary array of tropical birds in the lowland rainforest.

San José in February is exceptionally clear and pleasant. The city receives barely any rainfall—less than 0.2 inches (5 mm) for the month. Morning views of the surrounding volcanoes are sharp and detailed, and the air quality is the year's best. Daytime highs of 78–80°F (26–27°C) are comfortable, while cool evenings of 62–64°F (17–18°C) are pleasant for outdoor dining.

Volcano day trips from San José are at their very best in February. Poás Volcano is often clear in the early morning, with the distinctive aquamarine crater lake (Laguna Caliente) visible through sulfuric steam. Irazú Volcano offers views that on exceptionally clear February mornings extend to both the Pacific Ocean and the Caribbean Sea simultaneously—a truly rare sight possible only on the clearest days from the crater rim at 11,260 feet (3,432 meters).

February's excellent weather supports the full range of Costa Rica's outdoor activities. Wildlife watching is outstanding: scarlet macaw nesting along the Pacific coast is underway (February through May breeding season), leatherback turtle nesting at Playa Grande continues through February, and resplendent quetzal activity increases as breeding season begins to ramp up in the highlands.

The Lankester Botanical Garden near Cartago typically peaks in orchid blooming around February and March. With over 800 orchid species in the collection, a visit in February can reveal spectacular native and exotic specimens in full bloom. The garden also features bromeliad, heliconia, and palm collections that are beautiful year-round.

Adventure activities are all fully operational in February. Zip-lining at Monteverde or Arenal, white-water rafting (lower, beginner-friendly levels in dry season), ATV tours through Guanacaste dry forest, and horseback riding on Pacific beaches are all excellent. Yoga retreats in Nosara and Santa Teresa operate year-round and are particularly popular in February with travelers combining wellness and beach.

February falls in peak season, requiring advance planning and budgeting for higher prices. Mid-February (Valentine's Day through end of February) sees a temporary demand surge around the Valentine's holiday, with couples' packages at beach resorts selling out months in advance. Booking accommodations by November–December for February travel is recommended for popular destinations.

An alternative approach for budget-minded February travelers: opt for less-traveled but equally beautiful destinations. Playa Sámara (less crowded than Tamarindo), Dominical (less expensive than Manuel Antonio), and Puerto Viejo (fewer crowds than Pacific destinations) all offer excellent February weather at more accessible prices.

February's weather allows for ambitious multi-stop itineraries. Comfortable driving conditions on Pacific coast roads, excellent flight connections between regional airports, and predictable sunny mornings for long-distance drives make February ideal for exploring multiple destinations. Consider one-way car rentals between Liberia airport and San José airport to save backtracking time on a comprehensive circuit.
