The Lowdown
Alright, let’s get into it for Triple Peaks in feet and miles.
Straight up – this is a rough stretch. The first real chance of a wave is not until Saturday the 22nd, and we’re talking ankle-biters at 1 foot, maybe. The next 16 days are mostly a bust.
The only real highlight is on Wednesday the 2nd of September. Wednesday morning at Triple Peaks, the swell is only 2 to 3 feet out of the WSW, but the wind is glassy – dead calm, not a ripple. That’s a winner for cleaner-than-clean conditions. Swell energy is weak (93), and the period is short, so it’s not going to fire, but if you’ve got a soft top, this is your window. Sometimes there’s a crowd, so be ready to share.
After that, things get messy. On Sunday the 30th, a 6 to 8 foot swell rolls in, but the S and SSE wind at 12 to 15 mph ruins the face. By Monday the 31st of August, the swell is hitting 10 feet from the WSW, with 15 mph onshore winds – that’s for experts only, and with the wind blowing so hard, it’s honestly more of a kiteboarding scene.
Water temp is normal for this time of year. No big standouts, just a quiet, glassy morning on the horizon and a whole lot of waiting.
Rusty.

Information about the Three Peaks Surf forecast
The above surf forecast table for Three Peaks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Three Peaks can be found by selecting the local surf guide option on the grey menu. Our Three Peaks 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 (Three Peaks) 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 Three Peaks 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.
