Gili Islands in September

Dry season runs April through September, delivering those postcard-perfect days with minimal rain and calm seas. July and August see the biggest crowds and highest prices, but also the most reliable weather for diving and snorkeling. April through June offers the sweet spot - good weather, fewer tourists, and reasonable accommodation rates. The water visibility peaks during these months, making it prime time for underwater activities. Manta rays start showing up at Manta Point around April. September extends the good weather but brings Australian school holidays, so expect more families. October marks the beginning of the wet season, though it's often just afternoon showers rather than all-day rain. Wet season from November through March brings unpredictable weather. Some days are perfect, others see choppy seas and cancelled boat trips. But accommodation drops to half price, and you'll have beaches mostly to yourself. Just pack a rain jacket and flexible plans. Here's the thing about weather in Indonesia - it's changing. What used to be predictable seasons now shift unexpectedly. Check recent weather reports before booking, not just historical averages.
