The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, mate, it’s a pretty grim stretch for Three Peaks. The whole 16-day window is mostly flat, blown-out, or just plain messy. There’s a long, quiet gap right from the start, with nothing worth paddling out for. You’re looking at days of tiny, weak, onshore junk. The wind is all over the shop – cross-on, onshore, strong breezes – it’s gonna be chopped up and ugly. We don’t get a decent pulse until around Thursday the 19th of August, but even then, it’s got problems.
The standout, if you can even call it that, is Wednesday the 19th of August. The swell finally wakes up, pushing 8ft from the W with a short period of 8 seconds, and the combined energy jumps to 836 (moderate to strong). That’s got some grunt. Problem is, the wind is a cross-shore from the NW at 16 mph, so it’s gonna be a bit lumpy and cross-chop. This is big enough for experienced surfers only, and crowds are possible here at times. The afternoon cleans up a touch energy-wise (970) but it’s still marginal. For the brave, there might be some fun, punchy waves, but it’s not gonna be a glassy, perfect day.
Thursday the 20th of August morning might be your best bet for cleaner conditions. The swell drops to 4ft from the WNW (period 7 seconds, energy 270), but the wind turns cross-offshore from the N at 12 mph. It’ll be clean, but the swell is dropping fast. It’s a one-morning window before it gets tiny again.
After that, it’s back to the doldrums. Tiny, weak swells with poor winds all the way to the end of the forecast. Late in the run, around the 27th of August, we get a bit more size (5ft to 6ft) but it’s accompanied by rain and strong onshore or cross-onshore winds, making it a complete mess. Not worth it.
Overall, pick your moment very carefully. The 19th has the size but it’s rough. The morning of the 20th is clean but small. That’s all she wrote.
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.
