October is Lombok's last reliable dry month before the wet pattern returns in November. Rainfall stays low at 80mm across 6 days, dive visibility holds at 22–25m, and prices drop to about 15% below July peak. The MotoGP Mandalika race weekend (estimated October 5–6, 2026) creates a major price spike around Kuta Lombok and Mandalika.
# Lombok in October: The Last Dry Month
October is the dry season's farewell. The southeast trade winds weaken, surf eases off its August peak, and the air begins to feel slightly heavier — but the rainy pattern hasn't yet established. For travellers who missed the May sweet spot, October is the second-strongest dry-season value window. The catch this year is the MotoGP Mandalika race weekend, which transforms a quiet shoulder month into a high-spike single weekend on the south coast.
Daytime highs around 32°C, overnight lows around 23°C, humidity climbing back to 75%. Rainfall is 80mm across about 6 days — manageable, with most rain falling as brief late-afternoon showers rather than the prolonged thunderstorms of January. The first wet-pattern hints appear in the final week, but most days remain sunny.
Sea conditions are good. Dive and snorkel visibility holds at 22–25m for most of the month, with some clouding in the final week. Sea temperature climbs back to 28°C. Trade winds ease, leaving calmer surface conditions for sailing, snorkelling, and beginner surf.
The light feels different from August — softer, less sharp, more painterly. Photographers favour October for cultural and landscape work because the harsh trade-wind clarity gives way to gentler atmospheric conditions.
MotoGP Mandalika: Indonesia's round of the MotoGP world championship runs at the Pertamina Mandalika International Street Circuit on the south coast. The 2026 race weekend is estimated October 5–6 (verify with official MotoGP calendar — dates shift annually). The race draws 100,000+ international and domestic spectators, and accommodation within 30 minutes of Mandalika books out 3+ months ahead with prices spiking 200–400% for the four-night race period (Wed–Sun). If MotoGP is your goal, book early; if not, avoid Kuta Lombok and Mandalika that weekend or accept the spike.
Indonesian school holidays: A short school break runs in early October in some Indonesian regions, driving a brief domestic travel pulse mid-month.
No major Hindu or Muslim religious holidays in October 2026.
Surf eases: Trade winds weaken through the month. Surf becomes more friendly to intermediate and advanced beginners — south coast lineups thin out as the international surf-travel peak passes.
Diving: Operators continue full schedules but begin tapering in the final week. Manta ray and mola mola sightings remain possible at deep sites.
Rinjani trekking: October is the final month of comfortable Rinjani trekking before late-month rain risk grows. Bookings ease significantly compared to August.
Mount Rinjani: Last reliable trekking month before wet-season closure. Conditions remain good through about October 25; bookings dramatically easier than August. The 3D2N summit trek runs at near-peak success rates.
Kuta Lombok: Excellent value for most of the month — except the MotoGP weekend. Surf is friendlier than August, beach days are reliable, and accommodation rates ease back to shoulder territory. From October 7 onwards (post-MotoGP), south coast prices drop sharply.
Gili Islands: Strong month. Visibility 22–25m, fewer crowds than August, sunset photography reliable, and pricing eases through the month. Gili Air and Gili Meno especially pleasant.
Senggigi: Sunset cruises run daily. Easy room negotiations. Quietly the best base for west and north coast exploration.
Sembalun and highlands: Comfortable, cool, photogenic. Some pre-wet greening returns.
Mandalika: AVOID without booking unless attending MotoGP. The race weekend transforms the entire south coast.
About 15% below July peak in regular weeks, with MotoGP spike:
The cheapest weeks are October 12–25 (post-MotoGP, pre-wet-pattern). The most expensive window is October 1–7 (MotoGP).
October 12–25 is the year's second-strongest sweet-spot window after May. MotoGP weekend has cleared, the post-race accommodation glut drives sharp price drops in Kuta Lombok, the wet pattern hasn't yet established, and crowds remain low across the entire island. Visibility and weather are still firmly in dry-season territory. For Mount Rinjani specifically, this two-week window combines easier bookings than August with conditions that are within a hair of peak. For travellers who can't make May work, October 12–25 is the answer.
