October vs June

Best match

Last reliable dry month — Rinjani season closing, transition window for value seekers.

• ↑October is the last month before the wet season reasserts: conditions are still predominantly dry with 66mm of rain (mostly in brief late-afternoon showers) and 8 sunshine hours. The Gilis are at their quietest since May and prices are comfortably below the summer peak.
• ↑The Rinjani trekking season officially runs through October, and this late-season timing means the crater rim campsites can be booked at short notice — a flexibility impossible in July-August. The summit in October is cold and clear.

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.
