The Lowdown
Alright, Rusty here. Let's have a good hard look at what's on the cards for Three Peaks.
Bloody hell, it’s a tough start. We’re looking at a long, dry spell with not a single decent wave in the first week. The whole forecast period opens with a run of poor surf, churned up by strong westerly winds, starting Friday 4 September with a lumpy 6ft cross-on shore swell. That sets the tone. We’re looking at a solid gap of over a week before there’s even a whisper of something worth paddling for. The water is sitting at 66°F, which is a massive 5°F warmer than normal for this time of year – that’s very unusual, almost like summer has stuck around.
We finally get a brief moment of clarity on Saturday 12 September. The morning brings a cleaner look with a cross-offshore breeze from the NNW and small 3ft swell from the WSW, period a modest 8 seconds. The combined energy is weak, just 110, so it’s not going to be pumping, but it’s the only time the wind gets its act together. By the afternoon the cross-shore wind takes over and the swell drops away. Still, for a dedicated local, that Saturday morning session might be the one window with something rideable. But don't get your hopes up for anything special – it’s a long way from good.
After that, it’s back to tiny, blown-out dribble. A couple of mornings around the 15th of September show clean conditions with a cross-offshore breeze, but the swell is essentially flat at 0.7ft – you’d be dragging your knuckles on the sand.
The very tail end of the forecast, on Friday 18 September and into Saturday 19 September, shows some glassy conditions with the lightest of breezes, but the swell is down to 0.3ft to 1ft. There's one moment on the 19th with a 16-second period from the SW, which points to some very long-period energy, but the height is just 0.3ft. It’s a tease.
Honestly, for the entire 16-day window, there’s nothing that comes close to a standout session. The wave energy is consistently weak, the wind is mostly wrong, and the surf quality stays locked on "poor". This is one of those stretches where you’re better off finding something else to do. The forecasts can change, but looking at this, it’s a blank run that’s pretty normal for the area when the trade winds are unreliable.

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.
