Why September

September diverges from the Pacific pattern here. While the Pacific south enters its most brutal month, the Caribbean weather system that governs Arenal has already delivered its peak in July, and September in the Arenal basin is rain-heavy but occasionally punctuated by morning clearing windows that July never produced. The Cano Negro Wildlife Refuge to the north reaches its peak bird and wildlife concentration as the channels fill completely — the guided boat float through the refuge in September is the best of the year. The lava field trails remain wet but are increasingly navigable on mornings after a dry night.

What's possible this month
Book the Cano Negro Wildlife Refuge boat tour for the best bird-watching conditions of the year as wetland channels reach peak depth and diversity
Raft the Balsa River on still-elevated September flow as the wet season holds the water level close to its July peak
Night walk the property as September delivers peak wet-season amphibian activity — glass frogs, red-eyed tree frogs, and poison dart frogs at maximum density across the trail network
Look for morning volcano clearing windows — September's Caribbean-influenced weather occasionally delivers views that guests arriving in peak season never experience
Conditions

↓
Volcano remains largely hiddenSeptember has the highest number of rain days per month at Arenal and the cone is obscured on most days entirely. The Cano Negro wildlife tour is exceptional and the rafting is still productive, but guests who came for the volcano should have waited for November. The hot-spring and immersion experience is fully available and uncompromised.
