Costa Rica travel guide: when to go

✅ Dry Season (December–April): The classic choice

Costa Rica's Pacific dry season is everything the brochures promise: brilliant sunshine, flat turquoise seas along Guanacaste's best beaches (Playa Conchal, Tamarindo, Nosara), and wildlife that comes out to drink at drying water holes. February scores 9.2/10: 32°C, just 5mm of rain, and 10 hours of sunshine. This is prime time for snorkeling, kayaking, and seeing howler monkeys, scarlet macaws, and iguanas without the drama of afternoon thunderstorms. February and March are peak season — accommodation books out fast.

👍 July's "Veranillo": Costa Rica's secret best month

July is Costa Rica's great secret — a "little summer" (veranillo del Buey) that brings a dry spell to the Pacific coast mid-rainy season. Rainfall drops from June's 220mm to around 100mm, mornings are often sunny, the jungle is brilliantly green from the rains, and prices are 25–40% below dry-season peaks. Wildlife activity is at its annual maximum — baby sloths, nesting sea turtles (Caribbean coast), and waterfall hikes with full flows. An excellent choice for budget-conscious travellers who don't mind the occasional afternoon shower.

❌ September–October: The real wet season

September and October are genuinely the challenging months — rainfall can reach 290mm in September, roads flood, some lodges close, and the Pacific beaches are rough and grey. The Caribbean coast (Tortuguero, Puerto Viejo) actually has drier weather in these months, making it a viable alternative for turtle nesting season. Prices hit annual lows, and for adventurous budget travelers, Costa Rica's waterfalls and rivers are at their most dramatic.

FAQ

Costa Rica weather — frequently asked questions

December through April for the Pacific coast dry season — the classic answer, and deservedly so. Beaches are spectacular, wildlife is easily spotted at drying watering holes, and the sunshine is relentless. February is our top pick with a SunScore™ of 9.2. The secret alternative: July's veranillo (little summer) brings a dry spell mid-rainy season — lower prices, greener jungles, and all the wildlife with a fraction of the crowds. For sea turtle nesting, the Caribbean coast is best July–October.
Far more manageable than the name suggests — rainy season is typically afternoon rain, not all-day downpours. Mornings from May through November are often brilliantly sunny. The rain arrives around 2–3pm, storms hard for 1–3 hours, and stops. The rainforest turns an extraordinary emerald green. Wildlife activity actually increases. Prices drop 30–40%. The catch: September and October are genuinely wet with all-day rain possible, and some roads become impassable. If you go in rainy season, avoid Sep/Oct and pack a quality waterproof layer.
They have opposite weather patterns, which is the key planning insight. The Pacific coast (Guanacaste, Tamarindo, Nosara, Manuel Antonio, Dominical) is dry Dec–Apr and wet May–Nov. The Caribbean coast (Puerto Viejo, Tortuguero) is actually drier September–October when the Pacific is at its wettest, and wetter July–August when the Pacific has its veranillo. This means you can visit year-round by choosing the right coast. The Caribbean is known for leatherback turtle nesting (February–May) and green turtle nesting (July–October).
The veranillo del Buey ("little summer of the Ox") is a natural dry spell that typically occurs in late June through July on Costa Rica's Pacific coast. Trade winds shift, rainfall drops significantly (from 220mm in June to ~100mm in July), and mornings become reliably sunny again for 2–4 weeks. It's one of Costa Rica's best-kept secrets: the jungle is vibrantly green from the May–June rains, wildlife is hyperactive, prices are well below dry-season rates, and visitor numbers are manageable. The exact timing and duration varies by year, but late June and July are the safest window to catch it.
