The Lowdown
Alright, mate. Rusty here.
We’ve got a real mixed bag coming our way at Peak Rock over the next two and a half weeks. There’s plenty of swell on the table, but the wind is going to be the deciding factor for most of it. The water temp is sitting at about 57°, which is a touch warmer than usual for this time of year, so you might get away with a slightly thinner wetsuit.
The real standout, and the one you want to circle on the calendar, is Tuesday the 22nd of September. We’ve got a solid 12ft of SW groundswell rolling in with a very long 16-second period, pushing the combined energy way up to 6028. But the kicker? It’s absolutely glassy with zero wind. That is as perfect as it gets for a reef break like Peak Rock, offering up powerful, clean lines for experienced surfers only at that size.
Before that, there are a few other decent windows. Friday the 11th starts off with glassy 7ft SW swell (2394 energy) and excellent conditions for the experienced crew. That morning is your early call. Saturday the 12th also has a killer morning session with offshore wind and a clean 7ft SW swell. Then again on Friday the 18th, we see moderate offshore winds cleaning up a solid 7ft SW swell with a long 16-second period, which will shape up nicely.
The middle of the period is messy. From the afternoon of the 15th through the 17th, we get big cross-shore and onshore winds that are going to chop up the 10ft+ swells into a bit of a washing machine. A couple of those days with the strong onshores might actually be more fun for the kite crew than a paddle surfer. We then hit a lull around the 20th and 21st with small, weak surf in the 3ft range.
After that main event on the 22nd, the swell hangs in there at a still-chunky 8ft on Wednesday the 23rd morning with light offshore winds, so the quality will still be high for confident surfers. After that, it drops back down and the winds get iffy again, with a big but messy 12ft swell on the 26th being blown out. Keep your eye on that Tuesday the 22nd, that’s the one.
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.
