Month-by-Month Guide
January
Peak wet season brings daily downpours and steamy conditions, though the rainforest comes alive with waterfalls and wildlife activity. It's quite pleasant if you don't mind afternoon showers and plan indoor activities during heavy rain.
February
Still firmly in wet season with regular afternoon thunderstorms, but the landscape is incredibly lush and you'll have most attractions to yourself. Rivers run high, making boat trips through jungle waterways scenic.
March
Rain begins tapering off but humidity remains intense - you'll still get regular showers, typically brief but heavy. It's transition time, so pack for both wet weather and increasingly sunny days.
April
The shoulder season kicks in with more sunshine and less rain, making it ideal for outdoor activities. Everything's still green from the wet season, creating perfect conditions for photography and jungle treks.
May
One of the best months - drier weather settles in but the landscape hasn't browned yet. You'll find excellent conditions for river trips and cultural visits, though it's getting noticeably hotter as the dry season approaches.
June
Dry season proper begins with long sunny days and minimal rainfall. It's getting hot - hot - but the lower humidity makes it more bearable than you'd expect, for early morning activities.
July
Peak dry season brings the most reliable weather - you'll get weeks of sunshine with barely a drop of rain. It's also the hottest time of year, so plan accordingly with plenty of water and sun protection.
August
Arguably the best weather month - minimal rain, clear skies, and slightly less intense heat than July. Perfect for boat trips, diving, and long jungle treks, though you'll want to book accommodation well ahead.
September
Still dry but transition weather starts creeping in - you might catch the occasional shower, usually brief and refreshing. The landscape begins greening up, and humidity starts climbing again.
October
Wet season returns with increasing rainfall, though mornings often start clear and sunny. It's quite pleasant - the rain breaks the heat and the jungle looks spectacular with new growth everywhere.
November
Proper wet season resumes with regular afternoon storms and higher humidity. The bonus? Rivers and waterfalls are at their most impressive, and you'll find the best deals on accommodation and tours.
December
Wet season peaks again with frequent rain and the year's highest humidity. That said, it's still warm enough for swimming and the rainforest is at its most lively - just pack patience for weather delays.
