Surfing the Mentawai in the off-season, roughly November to March, means smaller, less consistent swell, more rain and variable to northwest winds that blow onshore at many west-facing reefs. In return, line-ups are much quieter and some operators publish lower rates. Expect mostly waist- to head-high surf, with glassy mornings and sheltered rights such as Burgerworld and Nipussi still working.
When is the Mentawai surf off-season?
The Mentawai Islands, off the west coast of Sumatra, have a main surf season from about April to October, peaking from June to August. The off-season, or wet season, is commonly described as November to March. It is not flat: the islands sit near the equator, winds are often light, and Southern Ocean swells still arrive, just less often. November and March are usually the more promising ends of the period, while December to February are the least reliable.
What are surf conditions like in the off-season?
Conditions change week to week rather than following one pattern:
- Wave size: typically about 2 to 5 ft faces, with occasional larger swells, especially in March.
- Wind: light and variable to northwest. The northwest monsoon can bring onshore spells at exposed west-facing reefs, but glassy mornings are common.
- Which waves work: waves sheltered from the northwest, especially some right-handers, tend to fare better. Commonly cited examples include Burgerworld and Nipussi in the Playgrounds.
Off-season months at a glance
| Month | Typical swell (face) | Wind pattern | Rain | Crowds |
|---|---|---|---|---|
| November | 2–5 ft; occasional 6 ft+ | Variable to NW; more onshore spells, some glassy days | High | Quiet |
| December | 2–5 ft; occasional 6 ft+ | Light NW or variable; mixed glassy and onshore | High to very high | Quiet |
| January | 2–5 ft; occasional 6 ft+ | Light, variable to NW; often glassy, with onshore periods | High to very high | Quiet |
| February | 2–5 ft; occasional 6 ft+ | Light NW or variable; mixed | High | Quiet |
| March | 3–6 ft, building | Variable, with more clean windows | High, easing later | Quiet to moderate |

Is the Mentawai off-season cheaper?
Sometimes. Some resorts and charter sellers advertise off-peak discounts or lower listed rates, especially from December to February. It is not universal: some charters reduce their schedules or do not run, and some land packages keep the same price. Ask each operator for the exact dates, inclusions and cancellation terms. Our page on Mentawai surf resort prices lists published ranges.
- Resorts: look for off-peak rates or longer-stay deals.
- Charters: fewer boats run, so check that your dates are actually scheduled.
- Board hire: availability is usually easier when fewer guests are in camp.
Are the Mentawai waves less crowded in the off-season?
Yes. With fewer boats and resort guests, line-ups are usually much quieter than from June to August.
- More waves each: fewer surfers means more waves per session.
- More choice: guides can take you to whichever reef suits the day without competing with other boats.
- Calmer pace: a good time for intermediates to build confidence on smaller days.

Local culture and exploration
With fewer visitors, the off-season can be a good time to learn more about the islands beyond the surf:
- Culture: some operators arrange respectful visits to Mentawai villages on Siberut; go with a local guide and follow their lead.
- Nature: snorkelling, jungle walks and island trips fill days when the surf is small. See what non-surfers can do in the Mentawai Islands.
- Community: buy from local businesses and try local food in Tua Pejat or Muara Siberut.
What is the weather like in the Mentawai wet season?
- Rain: rainfall is high, with November, December and January among the wettest months. Showers are frequent but often short, with sunny intervals.
- Humidity: high; drink plenty of water.
- Temperature: warm, with water about 27 to 29 °C all year, so boardshorts and a rash vest are enough.
What safety and permit rules apply in the off-season?
- Surf levy: the Mentawai regency charges foreign surfers a levy of IDR 2,000,000 per surfer for each 15-day period, set by regency regulation since February 2024; many operators collect it.
- Sea crossings: wet-season weather can disrupt ferries and speedboats, so keep buffer days at each end of the trip.
- Health: see a travel-medicine clinician about vaccinations and malaria advice, and carry insurance that covers evacuation. See is Mentawai surfing safe?
Tips for surfing the Mentawai in the off-season
- Stay flexible: check the forecast daily and be ready to change reefs. Our guide to reading the Mentawai surf forecast helps.
- Pick a base with options: a resort or camp with waves facing different directions handles changing winds best.
- Pack for small surf: bring a groveller or fish as well as your shortboard. See the Mentawai surf packing list.
Frequently asked questions
Is it worth surfing the Mentawai in December or January?
It can be, if you want quiet line-ups and accept smaller, less consistent surf and more rain. Surfers who need reliable size should travel between April and October.
How big are the waves in the Mentawai off-season?
Typically about 2 to 5 ft faces, with occasional larger swells. March often starts to build towards the main season.
Which Mentawai waves work in northwest winds?
Waves sheltered from the northwest, especially some right-handers, fare best. Burgerworld and Nipussi in the Playgrounds are commonly cited examples.
Do I need a wetsuit in the off-season?
No. The water stays around 27 to 29 °C all year. A rash vest or thin top is useful for sun and reef protection.
