Traveller notes on Gili Trawangan in August
Notes from nearby Nusa Penida (69 km away)
Gili Trawangan doesn't have its own notes for August yet — these are about Nusa Penida, close enough to share the season.
Nusa Penida's forum places August in the middle of the dry season, low humidity and probably one of the best windows weather-wise. Regulars flag the Bali-Lombok strait's wind as the real factor to watch here specifically — when it picks up, boat crossings and dive conditions can turn choppy — and recommend a jacket or shawl for cooler nights in the island's hillier spots.
Other months in Gili Trawangan
Gili Trawangan's forum calls July and August the pick of the year weather-wise, with regulars flagging late July as the point high season really kicks in — expect the busiest boats and beaches from here through September. The trade-off for the reliable weather is the crowds, so regulars suggest booking accommodation ahead.
