October marks the transition from Mentawai’s peak dry season into the quieter shoulder months. For surfers, this usually means two very important things:
- Fewer crowds in the lineup compared to July through September
- Still enough Indian Ocean swell to keep the reefs firing
It’s the time of year when the Mentawais start to breathe again. The charter boats thin out, the pace slows down, and sessions feel less competitive without losing that world-class Mentawai magic.
If you’re chasing perfect barrels every single day, August still takes the crown. But if you want quality surf, more flexibility, and a more relaxed experience overall, October might actually be one of the best times to surf Mentawai.
Weather in Mentawai During October
October sits right in the middle of the transition between dry season and wet season.
Average Weather in October
- Air Temperature: 27–31°C (81–88°F) during the day
- Night Temperature: 24–25°C (75–77°F)
- Water Temperature: 29–30°C (84–86°F)
- Humidity: 80–90%
- Sunshine: Usually clearer mornings with cloudier afternoons
- Rainfall: Passing tropical showers rather than full-day storms
The weather becomes slightly less predictable compared to peak season, but that unpredictability is also part of why October feels quieter and less crowded.
Most days still offer long sunny windows and warm tropical conditions perfect for surfing.
Surf Conditions in Mentawai in October
October is technically shoulder season, but Mentawai shoulder season still delivers better surf than many destinations during peak months.
Average Wave Conditions
- Wave Size: 3–6 ft average
- Larger Swells: Early October can still see solid SW pulses around 8 ft+
- Swell Direction: Mostly SSW to SW groundswells
- Consistency: Generally 4–6 good surf days per week
The biggest difference compared to June–August is not necessarily wave quality.
It’s the consistency and intensity.
October usually offers:
- Fewer oversized swell events
- More playful surf
- Longer sessions
- Easier wave counts
- Less crowded lineups
For many intermediate and everyday surfers, that balance actually makes October more enjoyable than peak season.
Early October vs Late October
October almost feels like two different surf seasons combined into one month.
Early October
Early October still carries late dry season energy.
Long-period SW swells can still light up waves like:
- Hollow Trees (HT’s)
- Kandui
- Rifles
- E-Bay
Expect cleaner barrels, more power, and occasional heavier sessions.
Late October
Late October becomes softer, more playful, and more forgiving overall.
Conditions shift toward:
- Smaller surf
- More manageable waves
- Cleaner fun-sized rights
- More beginner-friendly windows
This is often the sweet spot for:
- Couples surf trips
- Mixed-ability groups
- Longboarders
- Families
- Intermediate surfers
Mentawai Wind Patterns in October
October winds are more variable than peak dry season, but mornings still deliver excellent conditions across many reefs.
Morning Conditions
- Light E/SE offshore winds
- Usually glassy conditions
- Best surf window for most reefs
Afternoon Conditions
- Trade winds become more inconsistent
- Some exposed breaks may get choppy
- Sheltered reefs often stay clean
This is why staying close to multiple surf breaks becomes especially valuable during October.
Flexibility matters.
What to Expect at Hollow Trees (HT’s) in October
Hollow Trees, also known as Lance’s Right, remains one of the most consistent waves in the Mentawais throughout October.
Early October at HT’s
- Hollow barrels still very possible
- Late-season SW swells continue to hit
- More powerful conditions on larger pulses
Late October at HT’s
- More playful 3–5 ft surf
- Less intimidating conditions
- Longer and more relaxed sessions
And honestly, this is where October becomes special.
The crowd factor changes everything.
You spend less time competing in the lineup and more time actually surfing.
For many surfers, HT’s during October feels more enjoyable than the busier peak-season months.
Other Surf Breaks Near HT’s
One of the biggest advantages of staying near HT’s is variety.
When conditions shift, nearby waves often stay surfable.
Nearby Waves to Surf in October
- Lance’s Left: Great alternative when HT’s gets windy or crowded.
- Bintangs: Short barrels and playful walls for intermediate surfers.
- Mini HT’s: Fun option for smaller days and less experienced surfers.
- The Point: Starts lighting up more consistently as winds become more variable later in October.
This variety makes October ideal for:
- Surf families
- Groups with mixed abilities
- Surfers wanting multiple sessions daily
- Travelers who prefer flexibility over heavy conditions
Why October Works So Well at Villa Onu
October is the month where location matters most.
When winds, tides, and swell directions become more variable, staying directly in front of HT’s gives you immediate access to the best surf windows without wasting time traveling between islands.
That’s the advantage of staying at Villa Onu.
One session could be clean morning barrels at HT’s.
The next might be a playful sunset surf at nearby rights with almost nobody out.
And because October attracts a broader mix of travelers, the experience becomes more balanced overall.
Villa Onu works just as well for:
- Couples
- Families
- Mixed surf groups
- Non-surfers
- Intermediate surfers
With chef-prepared meals, concierge transfers, and direct access to multiple waves, the experience goes beyond just surfing.
