The Lowdown
Alright, this is Rusty. Let’s be straight with you, mate. This stretch of the forecast is a rough one for Three Peaks. The water is a warm 66°, which is a whopping 5° warmer than usual for this time of year – feels like a bath, but the surf just isn’t cooperating.
We’ve got a 16-day window, but the first real chance of anything worth paddling out for doesn’t kick in until Monday the 7th of September. Even then, it’s a tease. The week prior is a dead loss – poor surf and messy conditions across the board.
Monday morning the 7th sees a jump in the swell to 6 ft from the WSW, with a solid 13-second period. That’s a proper groundswell pumping energy into the water (combined energy of 1540), but the wind is a cross-shore from the WNW. It’s surfable, but it’s a grumpy, lumpy wave. The afternoon turns into a choppy mess with onshore wind. Not a standout.
The whole run from there is a battle with the wind. Most days are cross-on or cross-shore with a chop, and the wave heights drop. The energy levels are weak to moderate – nothing to get the heart racing. The swell keeps hitting mainly from the WSW, which is fine for the direction Three Peaks likes, but the quality is just not there.
There is a brief, weird flicker of hope on Saturday the 12th of September morning. The swell drops to 3 ft, but the wind is a light cross-offshore from the NNW, and the waves are described as clean. The energy is low (102) but it’s the cleanest the place will look. It’s a small wave, but it’s an option if you’re desperate.
The end of the second week, Thursday the 17th of September morning, brings a pulse of 4 ft from the W with a clean cross-offshore ESE wind. It’s another small window of okay surf, but the period is short at 7 seconds. It’s not going to bowl you over.
Bottom line: this is a classic flat spell for Three Peaks. There’s no standout day. The best you can hope for is a small, clean morning on the 12th or the 17th. The rest is a write-off. The forecasts can change, but right now, this is a waiting game.
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.
