The Lowdown
Grab your board, it’s gonna be a bit of a waiting game, but there’s some solid pulses coming through for Bommie Peak (Big Island). Water temp’s sitting at 85.1°, which is about 1.4° warmer than usual for this time of year—nothing crazy, but you’ll notice it’s a touch toastier than normal.
Right now, Monday morning is pretty flat and weak. We’ve got a 3.9ft SSW swell with a 14-second period, but the energy’s only 880 – that’s weak stuff. Cross-off breeze at 25 km/h keeps it clean, but it’s marginal at best. Honestly, Monday’s a write-off. The afternoon bumps up slightly to 3.6ft but it’s still nothing to get excited about.
Tuesday sees the swell ease back a bit to 3.6ft in the morning, but the period jumps to 18 seconds—that’s proper groundswell. Energy’s climbing to 1246, still moderate, but the long period means the reef will feel it. The afternoon pushes to 4.3ft at 17 seconds, energy up to 1478. It’s building.
Then Wednesday, the 9th, things start to wake up. We’re looking at 6.6ft from the south with a 15-second period. Combined energy hits 1922—that’s solidly moderate, pushing strong. Cross-off wind keeps it clean, though the morning has a bit of cloud and the afternoon brings a risk of thunderstorms. This is where it starts to feel real.
Thursday the 10th holds 5.6ft in the morning, 5.9ft in the afternoon, with period around 16-17 seconds. Energy climbs to 2121 by the afternoon. Still cross-off, still clean. It’s a consistent run now.
Friday the 11th is the first standout I’d paddle out for. Morning’s 4.9ft at 15 seconds, but the afternoon is the pick: same size, same period, and the wind drops to a gentle 15 km/h cross-off. The comment literally says “excellent surf conditions for experienced surfers.” This is a reef break, so that long period will give you proper walls, not closeouts. Energy’s moderate at 1229, but the quality is there.
Saturday the 12th is a bit of a mixed bag. Morning drops to 4.3ft but the period jumps back to 19 seconds—that’s very long. Energy’s 1993. The afternoon picks up to 5.6ft with a 19-second period, and energy spikes to 2783, which is the strongest we’ve seen. So it’s got size, it’s got power, but the tide conditions are still flagged as “questionable.” Not a bad day, just not the absolute peak.
Sunday the 13th pushes to 6.9ft from the SW, 17 seconds in the morning, 16 in the afternoon. Energy’s 2436 and 2218. That’s solid, meaty reef surf. Still cross-off, still clean. For an advanced crew, this is good. Anyone less experienced should sit this one out—over 4.9ft is pushing it, and at 6.9ft, Bommie Peak isn’t forgiving.
Monday the 14th backs off a touch to 5.9ft, period 16 seconds. Morning’s a bit stormy, but the afternoon is another one of those “excellent for experienced” calls. Energy around 1743-1771. Worth a sneaky session if the tide lines up.
Tuesday the 15th has a 6.6ft morning, dropping to 5.2ft by the afternoon. Period’s 15 seconds. It’s still surfable but not as sharp as the day before. Wednesday the 16th drops to 4.6ft morning, 4.9ft afternoon, period 14 seconds. Energy’s back down to 1011-1203. It’s tapering.
Then Thursday the 17th—watch out. Morning has a light NNE breeze, 10 km/h, cross-shore with small ripples. Swell’s 5.2ft at 14 seconds, energy 1517. Then the afternoon turns

Information about the Bommie Peak Surf forecast
The above surf forecast table for Bommie Peak provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bommie Peak can be found by selecting the local surf guide option on the grey menu. Our Bommie Peak surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Bommie Peak) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Bommie Peak may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Bommie Peak is 167 km (104 miles) from the city of Sungaipenuh. If you plan a holiday in Mentawi Islands, look for hotels and other accommodation in Sungaipenuh. Sungaipenuh has rooms for a wide range of budgets as well as car hire and transport links.
