If you’re looking to score world-class waves without the peak-season crowds, September is one of the best months to visit the Mentawai Islands. It’s the sweet spot where powerful Indian Ocean swells are still pumping, but the vibe is calmer, with more space in the lineup and often better value for travelers.
At Villa Onu, our September Sessions deals are designed for surfers who want it all: epic waves, warm water, and a stress-free setup for families, couples, or friends.
Why Surf Mentawai in September?
- Consistent Swells: September brings reliable SSW–SW swells averaging 4–8 ft, with the occasional bigger pulse (up to 10 ft). Perfect for scoring iconic waves like Lances Right, the Point, Lances Left, Bintangs, or any of the many waves on our doorstep.
- Offshore Winds: Light and variable breezes set up clean, perfect, hollow conditions at many breaks throughout the day, exactly what you dream about.
- Warm Water, No Wetsuit: At 28–30°C (82–86°F), leave the neoprene at home.
- Less Crowded Than Peak Season: Fewer charter boats and land-based surfers compared to July and August mean more waves to yourself.
Family-Friendly Surfing Conditions
While magazines love to showcase giant barrels, the reality is that September also brings plenty of fun, manageable days. You do not have to be a pro with a quiver of step ups to enjoy the waves here.
- Intermediate-Friendly Options: Breaks like Mini HTs, the Point or Beachbreak, are ideal for longboarders, kids, or anyone still building confidence.
- Surf Lessons for Beginners: Our in-house surf coach will take first-timers to the sand-bottom beach breaks for safe, fun sessions.
- Variety of Waves: Whether you’re chasing barrels at Lances Right or mellow walls for long rides, September delivers for every level.
Weather in September
Expect classic tropical Mentawai conditions:
- Daytime temps: 29–31°C (84–88°F)
