The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you — over the next 16 days, we are in a bit of a dry spell. Three Peaks is the only break on the radar, and honestly, it’s not firing. We’ve got a long stretch of poor surf conditions, with only a couple of moments that might be worth a paddle, but nothing to get excited about.
The water’s sitting at 69°F, which is a full 8°F warmer than usual for this time of year — that’s very unusual, almost like we’re in a tropical bubble. Nice for a swim, but doesn’t help the waves.
We kick off Monday the 17th with tiny, weak swell around 3 ft from the west, period just 6 seconds, and cross-onshore winds making it choppy — combined energy is a weak 47. Not worth getting wet. Tuesday and Wednesday stay poor, with swell building to 5 ft by Wednesday morning but still messy with fresh cross-onshore winds. Thursday the 20th afternoon sees a brief improvement: 4 ft west swell, clean conditions with a cross-offshore breeze, but the energy is still low at 115. Friday the 21st morning is the closest we get to a highlight: 2 ft west swell, light offshore winds from the NE, clean, and the comment says “surfable waves but very ordinary conditions.” It’s a 1 out of 10 in the books, but honestly, that’s the best we’ve got.
From there, it’s a long gap of tiny, clean but flat surf — 1.0 ft or less from the 22nd through the 25th, with very low energy (17 to 37). The 26th shows a pulse of 4 ft from the WSW, period 8 seconds, but cross-onshore winds spoil it. Then we hit the 28th of August, which is the only other standout: 7 ft WSW swell, period 10 seconds, combined energy jumping to 732 — that’s moderate to strong energy. But the comment says “marginal surf forecast or questionable tide conditions,” and winds are cross-onshore. It’s a 1 out of 10 again. This is bigger, but it’s not clean, and at 7 ft it’s getting into expert territory, especially with short period and messy wind.
The rest of the run into early September stays poor — fresh cross-onshore winds, lumpy conditions, and the swell drops back to 4 ft by the 1st. No real standout windows. If you’re desperate, Friday the 21st morning is your best bet for a clean, tiny wave, or you gamble on the 28th for more size but messy conditions. Otherwise, it’s a waiting game.
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.
