Lombok · Month comparison
April vs June
June ranks #1 overall vs April at #5. Peak dry season perfection — Rinjani, Gilis, and south coast all at their best before crowds arrive.
April
#5 of 12 months
Strong option
The dry season begins in earnest — Rinjani reopens and the Gilis transform.
- ↑April marks the opening of the Rinjani trekking season: the 3-day/2-night circuit to the crater rim (2,900m) and descent to the crater lake (Segara Anak at 2,000m) is legally accessible and the trail is drying. Starting the season early means smaller groups and more flexibility in choosing a guide and porter service from Senaru or Sembalun.
- ↑The Gili Islands shift character entirely: with rainfall dropping to 92mm and seas calming, the snorkelling on the Gili Air turtle site and the Gili Trawangan western reef is superb. The bioluminescent plankton in the shallows at night at Gili Meno is best experienced when the waters are calm — April begins the optimal window.
June
#1 of 12 months
Best match
Peak dry season perfection — Rinjani, Gilis, and south coast all at their best before crowds arrive.
- ↑June is the finest weather Lombok produces: 9.1 sunshine hours, 29mm of rain, and lower humidity than May. The Rinjani crater lake is accessible from the crater rim by a steep descent — camping beside the hot springs at Segara Anak Lake (2,000m altitude, with Rinjani's perfect cone reflected in the water) is one of the most spectacular campsites in Indonesia.
- ↑The Gili Islands in June offer snorkelling and diving conditions that rival the Maldives at a fraction of the cost: flat water, extraordinary visibility, and turtle encounters on almost every dive. The no-motorised-vehicle policy on all three Gilis means the only sounds are birdsong, cicadas, and the call to prayer from the mosque on Gili Meno.

April trade-offs
- ↓Still some rain in early April — the transition isn't always clean, and April can produce wet spells that delay trekking plans. Having flexibility in your Rinjani start date is important.
- ↓International visitor numbers are building: the Gilis in April still feel quiet but are noticeably busier than March.
June trade-offs
- ↓June is when Lombok begins appearing on more travel itineraries: accommodation on Gili T and in Kuta Lombok requires advance booking, and prices have moved from the affordable May levels to moderate.
- ↓The Rinjani National Park has tightened group size rules and requires permits booked through registered operators — last-minute arrangements are becoming harder to secure for popular dates.
