Quick answer: the best time to visit Lombok is the dry season, roughly April to October — and the sweet spots inside it are May–June and September, when you get full sunshine without the July–August crowds and prices. But ‘best’ depends on what you’re coming for: surf, summits, snorkeling or solitude all have slightly different calendars. Here’s the honest month-by-month picture.
The two seasons, in plain language
Dry season (roughly April–October): day after day of sunshine, temperatures around 30–31°C by day and low twenties at night, calm seas and superb underwater visibility — prime time for the Gili Islands, Rinjani treks and every beach on the island.
Wet season (November–March): the monsoon months, wettest in November through January. But here’s what brochures skip: rain usually comes in bursts rather than all-day washouts, the island turns spectacularly green, prices drop and crowds vanish. It’s a legitimate choice — just not for Rinjani, whose trails close in the heart of it.
Month by month
- January–February — wettest stretch; lush, quiet, cheap. Beach days happen between showers. Rinjani closed.
- March — rains easing; the island is green and empty. Good-value shoulder gamble.
- April — dry season arrives; Rinjani reopens (permit season begins); everything still uncrowded.
- May–June — the connoisseur’s window: perfect weather, hills still green from the rains, low crowds. Late May to early June is arguably the single finest fortnight of the year.
- July–August — peak season: driest skies, most consistent surf swell, busiest beaches and highest prices. Book Rinjani permits 2–3 months ahead and Gili rooms early.
- September — the other sweet spot: peak crowds gone, weather still flawless, seas warm and clear.
- October — late dry season; watch for MotoGP week at Mandalika (9–11 October 2026), which fills the south while leaving the rest of the island pleasantly calm.
- November–December — rains build; festive-season travellers still come for the green landscapes and quiet beaches at gentler prices.
Timing by what you love
- Trekking Rinjani: April–December (park open), with May–September the prime window — remember the 400-per-day permit quota and mandatory insurance.
- Snorkeling & diving the Gilis: dry season for the calmest crossings and best visibility.
- Surfing: waves year-round; the south coast pumps most consistently June–August.
- Events: MotoGP in October; the Bau Nyale festival (thousands gather on southern beaches for the sea-worm harvest tradition) falls around February–March by the Sasak lunar calendar.
- Sunsets: dry-season evenings on the west coast are ridiculous in the best way — the Senggigi–Mangsit strip faces the show directly, with Bali’s Mount Agung silhouetted across the strait (beachfront spots like Holiday Resort Lombok were essentially built around that view).
One honest warning about peak season
July and August are wonderful — that’s why everyone comes. But ‘everyone’ now includes Rinjani permit quotas selling out months ahead, Gili fast boats running full, and event weekends (like July’s 9,000-runner Pocari Sweat Run) booking Mandalika solid. Peak-season Lombok rewards planners. If spontaneity is your style, aim for May–June or September instead — same weather, half the fuss.
