The Lowdown
Alright, rusty here. Let’s take a look at what’s cookin’ for Three Peaks.
Honestly, the next week and a bit is pretty grim. We’ve got a long stretch of poor conditions with messy, choppy, cross-onshore wind dominating the forecast. The swell is mostly short-period windswell, in the 4 to 6 ft range, but it’s all blown out. The water’s gonna be a lot warmer than usual for September, about 64.6°, which is a solid 4.3° above normal – feels like a warm bath but not much else to get excited about.
The first real glimmer comes Sunday morning, September 20. A little 3 ft WSW swell and a light cross-offshore breeze will clean things up, but it’s just a small, ordinary wave. Nothing to write home about. Then Monday morning, September 21, is glassy with next to no wind, but the waves are tiny at 2 ft and weak (combined energy is only 53). The following days trickle along with small, clean but weak surf, with combined energies all under 135.
Now, the one that’s got my attention is Saturday, September 26. We’ve got a proper long-period groundswell arriving – 5.6 ft from the WSW with a 16-second period. That’s a very long period, and at a beach break like Three Peaks, that much separation can make the waves jack up and close out a bit, but the energy readings are huge, peaking at 1540 combined energy on the morning and 1288 in the afternoon. The wind is cross-offshore and clean in the afternoon, with a gentle breeze. That’s gonna be the standout session for experienced surfers – just heads up, that long period stuff can be tricky on a beach break, so pick your peak carefully.
Sunday the 27th still has some decent energy (361-214 combined energy) but the swell starts to drop, and the wind picks up again, so it’s not quite the same quality.
Overall, if you’ve got patience, wait for Saturday the 26th. That’s the only true standout in this long flat-to-mediocre stretch. The rest of the time, you’re better off doing something else.

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.
