Costa Rica
Best Time to Visit Los Chiles
Los Chiles sits on the northern border with Nicaragua, low and humid year-round. Rain defines the rhythm more than temperature — the dry season is December to April, the wet season is May to November.
✦ Go in January or February for the best balance of dry weather and manageable crowds.
✅ Best months
January and February are the sweet spot: reliably sunny for river trips and wildlife, and crowds are still manageable before the March surge.
🔥 Peak season
March and April: the driest, hottest months. Hotels fill with birders and sport fishers, and prices can double. Easter week (Semana Santa) is the busiest period.
💷 Shoulder (best value)
May and November — you get residual dry weather at the start and end of the rains, with 20–30% lower room rates and far fewer tourists.
🌙 Quietest & cheapest
September and October are the wettest months. River tours often cancel, roads get muddy, and wildlife recedes into the canopy. Great for near-empty lodges and deep discounts, but plan for rain all day.
