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.

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

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.
