Off-season — lowest travel prices with still acceptable climate.
October in Costa Rica offers acceptable conditions — but it's not among the top travel months. Those looking for ideal weather should visit in January, February, March, April, and December.
Daytime temperatures reach up to 26°C (79°F), cooling to 19°C (66°F) at night (daily average: 22°C (72°F)). With 4 sunshine hours per day and 18 rain days (286 mm (11.3 in)), this is one of the cloudier months. The water is a warm 28°C (82°F) — perfect for snorkelling and swimming.
An umbrella or waterproof jacket is essential. On rainy days, plan indoor activities like museums and markets.
Green season: rain every day, the hills turn lush and green, water birds everywhere. Surfers come for the Pacific waves. Lower prices and national parks in fresh green.
