The Lowdown
Alright, let’s break it down, folks. The only wave in town is Peak Rock, a reef break that’s pretty consistent and likes a south-southwest swell. It’s not a huge selection, but there are a few moments that are worth the drive.
We’re starting slow. Wednesday the 26th is a total washout with a messy cross-onshore wind and a lumpy 6ft SW swell – just leave the board in the truck. Thursday the 27th is where it gets interesting. The morning is clean with a 3ft SW swell and a light offshore breeze from the north-west, and it turns glassy in the afternoon. The swell bumps to 4ft, the period is 13 seconds, and the energy is moderate (567). That’s a proper clean, fun session for an intermediate.
Friday the 28th is a mixed bag. The morning is clean with a 5ft SW swell and a long 18-second period – that’s proper groundswell. The energy is strong (2159), but the wind is a cross-offshore, so it’s rideable. The afternoon, though, the wind goes onshore and the swell jumps to 7ft, turning it choppy and ugly.
The real standout, the one you’d mark on your calendar, is Monday the 31st of August. Both the morning and afternoon are firing. You’ve got a 7ft SW swell, a 15-second period, and light offshore winds from the north. The combined energy is strong (1985 and 2116). This is excellent surf for experienced surfers. The water temp is about average for the time of year, nothing unusual. Crowds are possible here, so get there early.
Tuesday the 1st of September has a strong offshore wind – 25 mph in the morning – which cleans the waves up but makes paddling a real workout. The swell is 5ft with a very long 16-second period, but that wind is a handful. The 4th of September Friday brings a big 8ft SW swell, and the afternoon is excellent with light winds – another one for the experienced crew.
The 5th of September Saturday morning is a beast: 10ft SW swell, 16-second period, and a combined energy of 7419 (very strong). That’s big, powerful, and only for the experts. The afternoon drops to 8ft with clean cross-offshore winds, still a solid session.
The second week gets rough. The 6th of September is a total loss with near gale-force winds and rain. The 7th is still howling. The 8th and 9th have some bigger swell (8ft to 10ft) but the winds are strong and lumpy, making it more of a fight than a fun session. The 10th of September looks similar with a strong cross-shore wind.
The takeaway: The best session is Monday the 31st of August at Peak Rock. Clean, 7ft SW groundswell, light offshore winds, and strong energy. For the experienced, the 4th and 5th of September offer big, powerful waves. The rest of the window is either onshore, too windy, or just plain messy.

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.
