When to go

Best time to visit Gili Islands

The Gilis sit in a tropical pattern with a drier stretch typically centered on May to October and a wetter stretch commonly around November to March.

Best overall window

May to October

Drier weather, steadier sea states, and often clearer water.

Outside that window

More frequent rain and occasional storms. Build buffer days for boat transfers.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
