September Tips
- •Many businesses close for renovations during this wettest month
- •Ferries run limited schedules and cancel frequently due to dangerous seas
- •Consider this a complete write-off for outdoor activities
All Months
November through April is prime time — dry skies, calm seas, and perfect diving conditions. December and January are peak season, so book accommodation early and expect higher prices. March and April get hot but still manageable, plus you'll have fewer crowds. May through October brings monsoon rains and rough seas. Many dive shops close, ferries get cancelled, and some resorts shut down completely. But here's a secret — late October can be incredible if you get lucky with weather. Prices drop by 40% and you'll have beaches almost to yourself. Just have backup plans for rainy days. The shoulder months of November and April offer the best balance of good weather and reasonable crowds.
