Table - best surf conditions forecast for Three Peaks over the next 16 days.
The Lowdown
Alright, let’s talk turkey. Over the next week and a half, Three Peaks is pretty much dead. There’s a whole lot of nothing – small waves, bad winds, and weak energy. The water’s running about 69°F, which is nearly 8°F warmer than normal for this time of year. That’s a seriously warm ocean, so the wetsuit can stay thin.
There’s one real glimmer of hope way out there, about ten days from now. On Wednesday, September 2nd, a bigger swell starts to show up. We’re talking 8ft in the morning, with a cross-off ESE breeze keeping it clean. The energy jumps to a strong 1107, and by the afternoon it’s pushing 10ft with an even bigger 1733 on the energy scale. That’s got some real punch, but it’s too big for beginners – this is expert territory only. The period is a modest 9 seconds, so it’s not the cleanest groundswell, but the size alone will get your heart rate up. That afternoon, it’s going to be a handful.
The real standout is Thursday morning, September 3rd. You’ve got 7ft of WSW swell, but the magic is in the wind: a solid offshore NNE breeze at 25 km/h. The energy is 669, and the forecast is calling for "very good surf conditions." For a beach break, an offshore wind is everything. That combination of size and clean conditions could be absolutely flawless. It’s a heavy, powerful wave, so it’s for the experienced crew, not the groms. Get on it early because the wind looks like it eases off and goes more cross-off later in the day.
Friday the 4th and Saturday the 5th still have some swell – around 5ft to 7ft – but the winds aren’t as clean. It’ll be surfable, but not the same quality as that Thursday morning push.
Before that, it’s a barren wasteland. No good options for at least a week. But when that Thursday morning rolls around, it’s going to be worth the wait. Keep your fingers crossed and your board ready.

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.
