The best Months to dive in Gili Trawangan

Scuba diving in Gili Trawangan is possible all year round but it is best to avoid December and January, when rainfall is at its heaviest. During this time, rainfall can cause surface run-off which reduces the visibility in sites close to the shore. Peak season for Gili Trawangan diving is from May to September but to see manta rays you’ll need to dip into the water from December through to March. While manta rays appear in the greatest numbers around these months, it is also your best chance to spot a whale shark from January through to March.
