The best time to visit the Gili Islands

The Gili Islands are a year-round destination, but the experience changes with the seasons. Like the rest of Lombok and Bali, the Gilis have two: a dry season from roughly April to October, and a wetter season from November to March.

The dry season is the most popular time to visit. Days are sunny, the sea is calm and clear, and visibility for diving and snorkelling is at its best. The trade-off is crowds and higher prices, which peak in July and August and again around Christmas and New Year. If you want dry-season weather without the crush, aim for the shoulder months of May, June and September, which tend to offer the best balance of good conditions and smaller crowds.

The wet season is not a write-off. Rain usually comes in short, heavy bursts rather than all-day downpours, and there is still plenty of sunshine between them. Prices drop, the islands feel calmer, and the diving can still be excellent on clear days. The main downsides are the occasional rough crossing, as fast boats from Bali are more likely to be delayed, and slightly reduced underwater visibility after heavy rain.

Water temperature stays warm all year, generally around 28 to 29 degrees, so a thin wetsuit or none at all is fine for most divers. Sea turtles are present year-round, which is one of the Gilis' biggest draws regardless of season.

If your trip is built around a specific event, such as a Gili Trawangan full-moon party, check the lunar calendar and book accommodation well ahead, as those dates fill fast in any season. Otherwise, for most travellers the sweet spot is the dry-season shoulder: reliable weather, calmer seas, and the islands at their relaxed best.
