The Lowdown
G’day, Rusty here. Let’s take a look at what’s cooking for Peak Rock.
The water temp is about 56°F, which is normal for this time of year—nothing wild.
Starting off Friday, August 28th: we’ve got a 5 ft SW swell with an 18-second period—that’s a lot of energy for this reef, combined energy at 1953. Morning has a cross-off NW wind, so clean faces, but it’s marginal due to tide. Afternoon goes cross-on and choppy—skip it.
Saturday the 29th: morning has 6 ft SW swell, 14-second period, cross-off wind, clean. Combined energy 1328. Afternoon turns messy.
Sunday the 30th: same story—clean morning, choppy afternoon.
First standout is Monday, August 31st. Morning has 7 ft SW swell, 14-second period, light cross-off wind, clean. Combined energy 1593. But the afternoon is glassy—6 ft SW, 14-second period, energy at 1955. Best session of the week: clean, lined-up, no wind.
Tuesday, September 1st: 6 ft SW, 16-second period, but a strong 25 mph offshore from the N. Clean but hard to paddle into—experts only.
Wednesday the 2nd: 7 ft SW, 14-second period, cross-off wind, energy 2107. Clean morning. Afternoon onshore.
Thursday the 3rd: 8 ft SW, 14-second period, fresh offshore wind all day, energy over 2100. Clean but strong.
The big one is Friday, September 4th. Morning has 12 ft SW swell, afternoon hits 13 ft SW, 13-14 second period. Combined energy is 7671 in the morning and 9945 in the afternoon. Clean cross-off wind. This is for experts only—huge energy.
Saturday the 5th: 8-10 ft SW, strong offshore wind, clean but tough.
Sunday the 6th: 12-13 ft SSW, short 9-11 second period, cross-onshore wind, lumpy. Total washout.
Monday the 7th: 6 ft SW, 11-second period, glassy morning. Energy 967. Small, clean, fun.
Tuesday the 8th and Wednesday the 9th: mostly onshore or choppy, with a clean moment Wednesday morning from 6 ft SW, 16-second period, energy 1753.
Another gem on Thursday, September 10th: morning has 4 ft SW, 14-second period, glassy calm. Energy 676. Small and perfect for a longboard.
Friday the 11th: 7 ft SW morning, 10 ft SW afternoon with an 18-second period, energy 6703. Clean moderate offshore wind—epic potential for the evening.
Saturday the 12th: 8 ft SW, 16-17 second period, light wind, energy over 4500. Clean and lined up.
The absolute best bets: Monday, August 31st afternoon for glassy perfection, and Friday, September 4th afternoon if you’ve got the nerve for big, clean waves. Thursday the 10th morning is a sleeper for small-wave fun.
See you in the water.

Information about the Peak Rock Surf forecast
The above surf forecast table for Peak Rock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Peak Rock can be found by selecting the local surf guide option on the grey menu. Our Peak Rock 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 (Peak Rock) 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 Peak Rock 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.
