The Lowdown
Hey, Rusty here again, looking at The Groyne. The outlook for the next couple of weeks is pretty bare, with a whole lot of junk and only one real bright spot.
Kicking things off, we’re staring at a long dry spell. From Friday the 21st all the way to Wednesday the 2nd of September, it’s just wave after wave of poor conditions. We’re dealing with tiny swell, mostly between 2ft and 3ft, and the wind is nearly always cross-onshore or cross-shore, leaving a nasty chop on the surface. The wave energy is weak to moderate (anything from 86 to 302 combined energy of all swells directed here), but it’s all low quality. There’s a short window on Saturday the 22nd morning when it went glassy (3ft from the East), but it’s so ordinary it’s not worth a special trip. The crowds can pop up sometimes, but with this forecast, the lineup will be empty.
But listen, I’ve got one day you need to circle. Thursday the 3rd of September. The morning session is the only real standout in the entire 16-day run. The swell will be a clean 4ft from the East, with a 10-second period, and the wind is glassy—a light NNE breeze with barely a ripple. That’s exactly what this reef break needs: clean, smooth faces. The wave energy will be moderate (253 combined energy of all swells directed here), and that longer period gives the waves some proper power and shape. It’s perfect for an intermediate surfer to get some quality rides. Do yourself a favor and be there for the morning. The afternoon of the same day gets ruined by a stronger wind.
After that, it’s back to the same old story—shifty winds, chop, and poor surf right through to the end of the forecast. The water temp is sitting around 68°, which is a touch colder than usual.
Bottom line: you’ve got one chance to score at The Groyne in the next two weeks, and that’s Thursday the 3rd of September in the early hours. The rest? Not worth the wetsuit.

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