Best time to snorkel in Gili Islands

The seasonal pattern for Gili Islands — what each stretch of the year tends to bring, and what to plan around. Guidance, not a forecast.

Seasonal pattern, not a forecast — conditions vary; verify tides, weather and visibility locally before you go.

The seasonal pattern

The Gili Islands sit in the tropics, so water temperature is never the planning question here — it is warm enough for a rashguard every month and long sessions are comfortable. Rain is what changes the picture, because runoff from Lombok and the islands themselves takes the edge off visibility in the shallow inshore water that is the whole snorkeling proposition. Broadly the region runs a drier season with steadier conditions and a wetter, hotter and more unsettled one, with the changeover months often giving the most comfortable water of the year. Because the islands are small and low, wind direction decides which coast you swim: whichever side is in the lee on the day is the one to use. Conditions also shift quickly in the channels at the change of tide, so plan your swims around the tide rather than through it, ask locally each morning, and take the calm early hours at Turtle Point and the underwater sculpture.

Go deeper on Gili Islands

Three tiny islands — Gili Trawangan, Gili Meno and Gili Air — just off Lombok's north-west coast in Indonesia, and the easiest genuinely good snorkeling in the region: fringing coral gardens and seagrass within a fin-kick or two of three separate shorelines, with green and hawksbill turtles a daily sighting rather than a lottery. There are no cars or motorbikes on any of the three, the water is warm year-round, and you can snorkel from the beach or take a short boat hop to a better patch. It is not untouched — these are small, popular islands and parts of the reef show it — but few places make snorkeling this simple.
