The Lowdown
Alright, Rusty here, checking in on the Peak Rock zone. We’ve got a slow start, but once it fires up, there’s some real juice in the water. The water temp is around 56°, which is a touch warmer than normal for this time of year, so you might not need the thickest rubber.
The first good window opens Thursday morning, the 20th of August. We’re looking at a clean 2ft SW groundswell with an 18-second period, and the wind is moderate offshore from the NW. The energy is moderate (350), and those long-period lines will be holding up nicely on the reef.
Things ramp up into the weekend. Saturday afternoon, the 22nd, is where it gets real. We’ve got 8ft of SW swell on a 15-second period, combined energy is high (2467), and the wind is a light cross-off from the WNW. The conditions are glassy enough, and it’s excellent for experienced surfers. This is a standout – solid groundswell lines and a reef to shape them up. The crowd profile says it gets busy sometimes, so get out there early.
Sunday afternoon, the 23rd, is another beauty. Same 7ft SW groundswell (14-second period), and here’s the kicker – glassy conditions, no wind. The energy is still strong (1667), and you’ll be paddling out into clean, walled-up sets. This is your other standout.
We’ve got a run of cleaner days through the following week, but it gets a bit mixed. The morning of the 26th of August has 6ft SW swell from the NE direction, with light cross-off winds – excellent conditions for the experienced crew. Then, big news for the 28th of August: Friday afternoon we see a massive 10ft SW groundswell, period of 16 seconds, with the wind light offshore from the NW. The combined energy is massive (5296). That’s expert territory only – the swell is over 8ft, but for those who can handle it, the reef will be handing out some freight trains.
There’s a bit of a dip after that with onshore winds and smaller swell for a few days, but the run into the start of September looks promising. The 3rd of September, Thursday morning, is a glassy, clean 6ft SW groundswell with an 18-second period. Perfect size for the intermediates, but that long period means it’ll be hitting the reef with real purpose.
All in all, the best is the Saturday 22nd and Sunday 23rd of August – solid groundswell, clean winds, and that reef is going to be working. Get on it.
Rusty.

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.
