Lombok (Gili) weather in June

June through late September is the stretch regulars recommend here: the dry season, the best surf of the year, and no strong winds to speak of - our 18.7 kph is a sea breeze rather than a problem. What they emphasise is the heat, and that the late-afternoon breeze is the relief you wait for. Our row reads 30.7C but 35C to stand in, at 80 percent humidity over 22.7C nights, with the sea at 28.7C offering no cooling at all. Rain has dropped to 41.9mm across 7.9 days. The surf worth travelling for is on the south coast rather than the small islands off the north-west. The record: 10.5 hours of sun and AQI 44.

Regulars are specific this month runs hotter than August while still usually landing just before the real rains return, part of a broader May-through-September stretch known for hot, sunny days and steady southeast trade winds. Our row backs that hot, genuinely dry read, 31.1C reading as a scorching 35C, over 22.8C nights feeling 26C, with rain light at 48.8mm across 6.4 days and humidity at 76 percent. Regulars are consistent rain here is genuinely location-dependent, the tourist-heavy south coast and Gili Islands typically seeing less of it than the west coast even on the same day. Southeast trade winds remain a steady, real feature worth planning around throughout. The record: 11.2 hours of sun, a 19.2 kph wind and AQI 46.

August sits in Lombok's drier half - June to September - and the forum describes it as mostly sunny with the occasional one-to-three-hour shower that then clears. The complication is the crossing rather than the island: July and August are when the wind picks up in the Bali-Lombok strait, and choppy seas are the other unpredictable period of the year for the Gili fast boats, alongside the wet season. August is also high season, so it is busy. Plan the boat day with some slack rather than on the last morning. The record: 30.5C days that feel like 33C, 21.7C nights, 3.2 precipitation days, 10.9 hours of sun, a 27.8C sea and a 21 kph breeze.

Forum posters are direct that January sits inside Indonesia's wet season here (which runs into late March), with rain a very frequent feature of the month - some days bring only a brief evening shower, others a genuinely torrential downpour, and posters are honest that sunny, rain-free days are the exception rather than the rule this time of year. That said, posters consistently push back on the idea that this means rain 'all day, every day' - even a wet stretch typically clears for stretches of sun, and one repeat January visitor reported plenty of sunshine and good snorkeling conditions right off the beach across two separate trips. Posters note the southern part of Lombok tends to see less rain than the north, giving flexibility for anyone building in a weather-dependent itinerary.

Lombok's forum calls July a favorite for the least humidity and driest conditions of the year, sunny most days with only the occasional 1-3 hour shower. Regulars trekking Mount Rinjani flag the mountain as an entirely different story — genuinely freezing overnight near the summit, 0-4°C, a sharp contrast to the warm coast below — and note late July into August brings stronger winds that can make the Gili crossing choppy.
