Costa Rica in April: Green Season Begins, Prices Drop, and the Country Opens Up

April is Costa Rica’s value pivot point. The green season rains typically begin arriving in the second half of April — afternoon showers appearing first in Guanacaste, building toward the sustained rainy season that peaks June–September. The country responds: prices drop 20–40% across accommodation and tours, the Pacific crowds thin dramatically, and the landscape begins the transformation from dry-season brown to the extraordinary green that Costa Rica is actually named for. April is the month when experienced travelers recognize the value opportunity.

Weather & Conditions

Guanacaste: 26–36°C. Dry mornings transitioning to afternoon showers by late April.

Manuel Antonio: 25–32°C. More variable. Rain arriving more consistently than Guanacaste.

Arenal: 22–28°C. Increasing rain. Mornings often clear.

Caribbean coast: 24–30°C. This is the Caribbean’s drier period (February–April are the least rainy months on the Caribbean side).

Osa Peninsula: 24–32°C. Rain beginning to arrive.

What to Do

Caribbean coast — April dry window: The Caribbean coast’s seasonal pattern is inverted from the Pacific’s. April and May are the Caribbean’s drier months (the primary wet season on the Caribbean is from June through December). April is therefore the best time to visit Puerto Viejo de Talamanca, Cahuita National Park, and Tortuguero — when the Pacific is getting its first rains, the Caribbean is at its most reliable.

Cahuita National Park: The coral reef at Cahuita is the most accessible in Costa Rica — snorkeling directly off the park’s beach gives encounters with parrotfish, angelfish, and sea turtles. The beach trail through the park (easy, flat, 3km each way) runs alongside the Caribbean through palm forest with red land crabs, howler monkeys, and the distinctive Caribbean pace. April’s dry window makes trail conditions excellent.

Puerto Viejo de Talamanca: The Caribbean town that functions differently from the Pacific resort culture — reggae, Afro-Caribbean food (rice and beans cooked in coconut milk, rondon seafood stew), and a pace that resists tourist pressure. April is the best month for the town and the surrounding beaches (Playa Cocles, Playa Chiquita, Punta Uva).

Green season Arenal launch: April in Arenal means more green, more jungle atmosphere, and the beginning of Arenal’s ideal conditions for waterfall excursions (the La Fortuna Waterfall reaches better flow in the rainy season). The Arenal Hanging Bridges and the hot springs around La Fortuna operate year-round.

Sarapiquí River rafting: The rivers running down from the central highlands to the Caribbean lowlands (Sarapiquí, Pacuare) build flow in April as the rainy season begins. April marks the start of the rafting season for Class III–IV whitewater. The Pacuare River is considered one of the world’s finest multi-day rafting rivers.

Festivals & Events

Easter (Semana Santa, variable April or March): The week before Easter is Costa Rica’s biggest holiday. If it falls in April, expect extreme domestic travel demand and price spikes around the holiday week itself — with rapid price recovery after Easter passes.

Practical Tips

Green season transition: April rains are typically afternoon showers (3–6pm) rather than all-day downpours. Morning activities (hiking, wildlife tours) are usually unaffected. Pack a light rain jacket but plan morning starts for outdoor activities.

Easter week vs. green season: the days immediately after Easter Sunday often see the lowest prices of the year. If Easter falls in April, the week after is one of Costa Rica’s genuinely cheapest and most relaxed travel weeks.

Caribbean April: this is specifically the time to flip from Pacific to Caribbean. The pattern is inverted and April-May gives the best conditions on both coasts sequentially.

Car rental green season: rates drop significantly after the Easter holiday period. April non-holiday weeks see 25–40% lower rental rates than January.

Who April Is For

Value travelers who understand the seasonal pricing logic. Caribbean coast travelers timing the dry window. Rafting and waterfall visitors who need river flow. Birders targeting the final quetzal nesting weeks in the highlands. And anyone who wants Costa Rica fully open and functional at significantly lower prices — the green season’s reputation for “always raining” is exaggerated in April.
