The Lowdown
Alright, this is Rusty checking in with a look at what’s ahead for Peak Rock.
We’ve got a serious run of solid swell coming in over the next couple of weeks. The water’s sitting at 56°, which is just a tick warmer than you’d normally expect for late August – not a wild anomaly, but a nice little bonus.
We kick things off on Saturday the 29th of August with a strong pulse of south-west groundswell. Saturday morning is the clear winner here. We’re looking at a clean 6 feet on the face, with a period of 14 seconds – that’s proper groundswell energy. The combined swell energy is sitting at a beefy 1327, so you’ll feel that power. Wind’s a gentle cross-offshore from the west, leaving the surface glassy. Peak Rock is a reef setup, and this long-period swell will wrap in perfectly. It gets a little criss-cross in the afternoon, so make the most of the morning. Crowds are sometimes an issue here, but with quality like this, you can expect a few others in the water.
Sunday hangs in there with similar 6 feet, but the wind stays cross-off in the morning – still clean enough, but the energy drops a touch to 1217. It’s not a standout, but it’s fun.
Monday the 31st is where it starts to ramp up. Another solid 7 feet, 14-second south-west swell in the morning, with a clean cross-off breeze. The energy has jumped to 1828 – you’ll feel that push. This is a proper session for intermediate surfers; the 7 feet is a solid size. The wind dies off in the afternoon but swings a little cross-on, so again, mornings are the call.
Now, look ahead to Saturday the 5th of September. A big 13 feet south-west swell hits, but the wind is a nasty near-gale from the west-south-west, screaming at 31 mph. The combined energy is a massive 6505, but the surface will be a complete mess of cross-shore chop. That’s kite-surfing territory, not a fun day on a paddle board. Forget it.
The real standout, and I mean the one to circle on the calendar, is Wednesday the 9th of September. During the afternoon, we get a beast of a 10 feet south-west groundswell with a period of 17 seconds. The combined energy goes nuts at 9180. But the magic is the wind: a light breeze from the west, keeping the surface glassy clean. This is an expert-only day – 10 feet on a reef is serious, and the period is so long these waves will be bowling. For the experienced crew, this is as good as it gets.
Following that, Thursday the 10th afternoon holds another 10 feet clean session, and Friday the 11th offers excellent, clean 6 feet to 6 feet waves with offshore winds – perfect for the intermediate surfer wanting to score after the big swell drops.
Later on, Saturday the 12th afternoon is another gem: 7 feet, a 16-second period, and gentle offshore wind. Clean and powerful.
So to sum it up: mornings are usually your friend here. Don’t bother with the 5th of September. Live for the 9th of September afternoon if you’ve got the skills. And don’t sleep on the 12th afternoon, either.
Stay salty,
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.
