The Lowdown
Alright folks, Rusty here with a look at the next couple of weeks for Three Peaks. To be straight with you, it’s a bit of a rough patch ahead. We’ve got some size on the board at times, but the wind just won’t play ball for most of it.
The overriding story for the next week or so is a whole heap of cross-shore and onshore wind. The first few days are a total write-off. Thursday the 4th and Friday the 5th have you battling 19 mph cross-on breezes for messy, lumpy waves in the 3.3 ft to 7.2 ft range. Not worth waxing up for. That trend continues through the weekend with smaller, choppy conditions. The real kicker is Monday the 7th. The swell jumps up to 6.9 ft with a nice long 13-second period from the WSW, carrying some serious grunt. But the wind is a moderate cross-shore breeze, leaving it a lumpy, cross-chop mess. What could have been a standout is just a frustrating "what if." If you’re an expert with a big board and don’t mind the chop, you could get some power, but it’s not for the faint of heart.
The best option in this whole 16-day window is actually the very last day, Saturday the 19th of September. Now, it’s a long way off, so don’t book your flights yet, but the models are hinting at something promising. The swell is small, only 2.0 ft from the W, but it's got a decent 10-second period. The wind is forecast to be glassy from the NE at 0 mph. That is *exactly* what we need to turn a small day into a fun one. For clean, tiny waves on a longboard, this is your moment. There’s a chance of crowds here, so get there early. For a proper surfer’s session, this is the one to circle on the calendar.

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.
