The Lowdown
Alright folks, Rusty here. Let’s look at what’s going on in our neck of the woods.
We’re looking at a stretch that starts a bit slow, but there’s a window of decent swell coming up. The main event is a solid pulse of SSW groundswell hitting around the 6th and 7th of September. The water is running about 75°, which is much warmer than normal for this time of year, so you can leave the thick rubber at home.
The standout is Rockpile, a consistent reef break that’s a good spot for beginners. The best session on offer is Sunday afternoon, the 6th of September. We’ve got a 6 ft SSW swell with a period of 14 seconds, and the wind is light and cross-offshore, making for clean conditions. The energy is solid (1448), and it’s an excellent call for experienced surfers. It’s a bit too big for the groms and beginners, though. Crowds are often a thing here, so expect company.
Leading up to that, Thursday the 3rd and Friday the 4th are small and choppy – not worth paddling out. Saturday morning the 5th is a bit of a write-off too, with cross-shore winds and swell around 3 ft. The wave energy is building (982) but the wind isn’t cooperating.
After the Sunday peak, Monday the 7th holds a similar 6 ft swell but with cross-shore winds, making it a bit lumpy. The energy is still strong (1156). By Tuesday the 8th, the swell drops to 5 ft and the wind turns cross-onshore, so it’s choppy again.
From Wednesday the 9th onward, we’re back to smaller, marginal surf. The period stays long (16-20 seconds), and the swell is from the SW, but the heights are down around 2 ft to 4 ft. The wind is mostly cross or cross-onshore, so it’s a bit of a wait for the next real pulse. The 18th of September shows a 3 ft SW swell with a 19-second period and light cross-shore wind, which might be fun for a log, but it’s nothing to get excited about.
Overall, if you’re keen, the Sunday the 6th is your best bet. The rest of the window is mostly small and bumpy.

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