Cleanest glass, lighter crowds, shoulder pricing — for those who can travel outside school holidays, September is the smart pick.
September at Don Don is the connoisseur's month. The Southeast trades soften from August's full-throttle peak, mornings stretch glassy longer (often clean until 11 AM), the swell remains consistent but slightly smaller and more playful, and the European/Australian holiday crowds have largely gone home. For surfers who can travel outside school holidays, September is arguably the best month at Don Don — almost everything that makes July great with a fraction of the lineup pressure.
# Don Don Surf Break in September: The Smart Surfer's Month
September is the month that experienced Lombok regulars quietly hope you don't read about. The Southeast trade winds, which spent August at full intensity, soften through September. The Indian Ocean groundswell remains consistent but slightly smaller and more playful than August's peak. The European and Australian school holidays end, and the strike-trip crowds thin dramatically. What remains is the cleanest, most enjoyable version of Don Don available all year.
Three factors line up in September:
Wind softens. The morning glass window stretches from a barely-five-minute August dawn to a comfortable 5:30-10 AM in September. You can paddle out at 7 AM, surf for two hours, and still finish in clean conditions. The afternoon wind also turns later and weaker, sometimes giving you an evening glass-off session that simply doesn't exist in July-August.
Swell remains consistent. The Roaring Forties storm machine doesn't switch off when September arrives. Groundswell continues to push north toward Indonesia. The waves are slightly smaller than August (chest-to-overhead is the typical range, vs August's overhead-plus) but more user-friendly, with longer walls and friendlier takeoffs.
Crowds drop. European summer holidays end early September. Australian school terms resume mid-September. The Indonesian school break has long passed. The strike-trip surfer count at Don Don roughly halves between mid-August and mid-September.
Expect:
Late September sometimes sees the first hints of wet-season transition — a stray afternoon thunderstorm, slightly more humid mornings — but these are exceptions not the rule. October is when transition really begins.
Roughly half the July peak. A typical September dawn at Don Don might see:
The vibe shifts as a result. The local crew is more relaxed, more willing to share waves with respectful visitors, and the foreign regulars who weren't around in busy July reappear. Conversation in the lineup is more common, set rotation more flexible.
You still need to respect lineup etiquette, but the pressure of July's crowd is absent.
September is shoulder season, which is reflected throughout South Lombok:
You can negotiate at most prices in September because everyone is happy to have customers after the August peak.
If you've been intermediate for years and want to break through, September is the month to invest in coaching. The reasons:
A typical four-day September coaching block at Selong Belanak with Don Don sessions runs 4-6M IDR all-in (coaching, board rental, boats, snacks). Worth it if you've been stuck at the same level.
Long sessions: Glass holds until late, you can surf 7-10:30 AM without rushing.
Combining breaks: Morning at Don Don, breakfast back at Selong Belanak, afternoon scout to Tampah or Inside Ekas. You can actually fit two surf locations in one day in September.
Photo trips: Without August's full lineup, you can have a photographer set up on the headland and get clean shots of yourself surfing without 50 other surfers in frame.
Yoga and surf packages: Several Selong Belanak villas run yoga + surf retreats in September because conditions and crowds align perfectly. Worth considering if you want a structured trip.
Guarantee on the biggest swell events: August is more reliable for huge swells. September can have huge swells too, but it's less of a sure thing.
Beginner sessions at Don Don: It's still a reef break with steep takeoffs. The reduced crowd doesn't change the wave's skill demand.
Late-September after about the 25th: Sometimes early signs of wet season transition appear. Surfable, but the consistency starts to slip.
If you can travel outside northern hemisphere school holidays, September at Don Don is genuinely the smart pick. You get most of August's quality with a fraction of the crowds and pricing. The weather is excellent, the wave is on, the local crew is relaxed, and the connoisseur regulars are there for company in the lineup. Plan a 7-10 day trip, base in Selong Belanak, and surf both Don Don and the surrounding South Lombok breaks.
September is when long-term Lombok-based surf coaches actually have time to run proper coaching sessions with video review and follow-up. In July-August they're slammed with strike-trip clients and group bookings. In September, you can book a one-on-one with one of the experienced French or Brazilian coaches in Selong Belanak for 800k-1.2M IDR per session and actually get individualized feedback that improves your surfing. If you've been at the same level for years, this is the month to book three coaching sessions in a row and finally break through.
