Excellent shoulder month outside MotoGP week — same swell as September with lower crowds and prices. Avoid race week unless you want MotoGP.
October is shoulder season at Gerupuk Bay with one major exception: MotoGP week (early October) brings massive accommodation pressure to the Kuta-Mandalika area. Outside reef downsizes to 5-8 foot, Inside remains workable for intermediates, and Don Don evening sessions stay reliable. Crowds drop significantly outside MotoGP week. Boat costs ease to 150-200k IDR. Rainfall returns gradually toward month-end.
# Gerupuk Bay in October: Shoulder Begins, MotoGP Erupts
October at Gerupuk Bay is two distinct experiences. MotoGP week is its own thing — a brief, chaotic surge that affects the entire south coast. The other three weeks are classic shoulder season at its best: easing crowds, workable swell, and meaningful price drops.
October weather marks the first hints of seasonal change. Rainfall edges up to around 80mm across 7 days. Most of October is still dry — afternoon showers begin appearing in the second half of the month, brief and isolated rather than the sustained storms of wet season.
Temperature stays warm: 31°C high, 23°C low. Humidity rises slightly to 78%. The dry-season clarity persists into early October, gradually giving way to occasional haze by month-end.
Trade winds become less consistent. Early October still has reliable southeast offshore through morning at Outside; by late October the wind pattern is more variable, with days where you'll get unexpected onshore conditions.
The Southern Ocean storm season weakens through October:
Inside Gerupuk: 4-6 foot consistent. Returning toward intermediate-friendly territory.
Outside Gerupuk: 5-8 foot most days, with occasional larger swells producing 8-10 foot days. Significantly smaller than peak July-September but still substantial.
Don Don: 4-6 foot evening sessions. The afternoon glass-off pattern persists through early October, becomes less reliable by late month.
Pelawangan: Less consistent than peak summer. Swell direction shifts and Pelawangan is more sensitive to direction than Outside.
Kids Point: More viable as Inside downsizes.
The MotoGP Indonesian Grand Prix at Pertamina Mandalika Circuit (10 minutes from Kuta) is the single biggest annual event on Lombok's calendar. For 2026, expect the event in early October — confirm exact dates with official MotoGP sources or local accommodation providers.
MotoGP week impact:
Accommodation prices: Spike 200-400% across all of Kuta, Mandalika, and surrounding areas. Even basic homestays charge premium rates. Some accommodations have minimum 4-7 night bookings during race week.
Traffic: The road from Praya airport to Kuta becomes severely congested. Plan extra travel time. Some local roads close for race operations.
Surf operations: Boats and surf schools still operate but are stretched thin handling MotoGP visitors who add surf experiences to their race trip.
Restaurants: Booked solid in Kuta during race nights. Make reservations or eat at off-peak times.
Lineup at Gerupuk: Some impact from MotoGP visitors trying surf for the first time. Inside gets more crowded with curious first-timers.
The three non-MotoGP weeks of October are excellent shoulder season:
Crowd reality: Outside has 8-15 surfers mid-morning. Inside 12-25 including reduced surf-school presence. Don Don 12-20 at evening. Lineups feel relaxed compared to peak summer.
Pricing: Boat charters 150,000-200,000 IDR shared, 275,000-375,000 private. Kuta accommodation 350,000-650,000 mid-range bungalows, 700,000-1,500,000 premium villas. Surf lessons 450,000-650,000 IDR.
Booking timeline: 4-6 weeks ahead is sufficient. Walk-in possible for budget options through most of the month.
The week immediately after MotoGP is particularly underrated — surf operators have flexed up for race week and have surplus capacity, leading to quietly negotiable rates.
October trip planning depends entirely on MotoGP positioning:
Strategy A — Avoid MotoGP: Travel mid-to-late October. You'll get shoulder-season conditions at shoulder-season prices with relaxed crowds.
Strategy B — Attend MotoGP: Build trip around race week. Arrive 3-4 days before for surf, attend race, surf 3-4 days after as crowds disperse.
Strategy C — Bookend MotoGP: Surf the week before MotoGP (clean conditions, building event energy), leave for the race week, return for the post-MotoGP calm.
Whichever you choose, confirm 2026 MotoGP dates early. The race date drives all other planning.
October is when you can return to lighter equipment:
Standard shortboard: Primary board for most October sessions
Step-up: Backup for occasional bigger days (pre-MotoGP week sometimes produces last big swells)
Mid-length (optional): For Inside lazy days as conditions soften
If you're flying with one board, your standard shortboard is the right choice.
The second half of October introduces the first afternoon showers in months. They're typically:
Morning surf sessions remain mostly unaffected. Evening Don Don sessions occasionally get rained out toward month-end.
By November, the rain pattern intensifies significantly. October is the last month before genuine seasonal transition.
October works well for:
October is wrong for:
For most intermediate to advanced surfers, mid-to-late October is among the year's best value windows.
Avoid MotoGP week (early October — confirm exact 2026 dates) unless you specifically want to attend the race. Accommodation prices spike 200-400% across all of Kuta and the surrounding area, traffic is brutal, and surf-related services are stretched thin. The week immediately after MotoGP (mid-October) is the value sweet spot — equipment, accommodation, and lineups all become noticeably easier.
