The Lowdown

Alright, surfers, Rusty here. Let's talk about what we've got on the cards at Rockpiles. It's a reef set-up, exposed and pretty consistent, and it loves swell from the SSE.

Right now, we're looking at a pretty grim run of surf. The water temp is sitting at about 80°F which feels about normal for this time of year, so that's one nice thing, but the waves? Not much to write home about for a stretch. From Saturday the 22nd right through to the end of August, it's a mix of poor and marginal conditions. We've got a persistent, strong ENE breeze blowing cross-off, which keeps things clean in a way, but the swell is all short-period, onshore wind-slop from the ENE, mostly around 5ft to 6ft. The energy is weak to moderate and the quality is just not there. It's a frustrating block of days where the ocean looks bumpy and uninviting.

Things start to shift a little in the first few days of September. On the 2nd (a Wednesday), we get a brief window of something proper. The wind goes glassy—first a light SE, then dead calm. Swell drops right back to a clean 3ft from the south, with a decent 16 to 17 second period. The energy is moderate. It's small, but clean, and a proper groundswell pulse. This is a gem for the small-wave crew. For a more advanced break like Rockpiles, that glassy south swell will offer up some nicely shaped, walled-up waves on the reef.

Then on the 4th of September (Friday), the afternoon picks up again. We get a burst of 5ft ENE windswell with clean cross-off winds. It's not a classic, but it'll be surfable.

Now, the standout for the entire forecast is the weekend of the 5th and 6th of September. The 5th (Saturday) sees a powerful pulse arriving: about 4ft to 6ft from the east with a long 16-second period. The energy jumps to strong levels. The wind is cross-off from the ENE, so conditions are clean. But the real one to keep your eye on is Sunday the 6th of September. We're looking at a proper pulse of swell, hitting 10ft from the ENE but with a shorter 13-14 second period. The energy is very strong. This is one for experts only; that's a lot of water moving around on the reef. It's a long way out, so keep an eye on it, but the potential is huge for a heavy, powerful session if you've got the skills and the nerve.

Okay, that's the picture from here. Stay safe out there.

Information about the Rockpiles Surf forecast

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