The Island Has Two Faces
Dry from April to October: brown hills, settled seas, and the surf season. Wet from November: green, humid, and a different island entirely.
When to visit Sumbawa
April to October for sun, passable roads and surf. Outside that, fewer people and a greener island.
The dry season is the straightforward answer and the busy one. Prices and lineups both peak in July and August.
Patterns, not promises. El Niño years and local anomalies move all of this, and nobody can book you a good week in advance.
- Dry
- April to October. Sunniest, driest, and the core surf window.
- Wet
- November to March. Rain in bursts, greener hills, smaller surf.
- Busiest
- July and August. Book six to nine months ahead.
- Quietest
- February and March. Cheapest, and the least reliable weather.
- Whale sharks
- Broadly year-round in Saleh Bay, calmer seas in the dry months.
The Year at a Glance
One strip, twelve months. Everything below is a pattern rather than a forecast.
April – October
Dry Season
Southeast trades, consistent Indian Ocean swell, dry roads and brown hills. The island at its most straightforward and its most booked.
Surfers, first-time visitors
November, March
Shoulder
Transitional winds and mixed swell. Glassy mornings, thinner crowds, and prices below the peak.
Mixed groups, better value
December – February
Wet Season
Rain in heavy bursts rather than all day. Green hills, smaller surf, and some dirt roads that stop being roads.
Intermediates, longboarders
We do not promise bluebird days or wildlife on cue. If your dates fall in a weak window we will tell you before you book, not after.
What Each Season Does to Your Trip
