The Lowdown
G’day, Rusty here. Look, I’ve got to be straight with you – this 16-day window for The Groyne is a tough one. The forecast is a pretty bleak run, with the entire first week and most of the second week looking like a write-off. We’re looking at a solid 11-day gap from the start of the period with no real surf to speak of. The swell is either tiny, short-period, or blown out by messy cross-shore winds. It’s just poor surf conditions day after day.
The only glimmer of hope comes right at the tail end of the period. On the morning of Thursday, September 17th, we finally get a break in the gloom. The wind goes glassy, absolutely dead calm, which is a huge positive for a reef break that’s exposed to the swell. We’ll have a tiny 2.6 ft swell rolling in from the ENE, but with that glassy surface, it’s the only time in the whole forecast that conditions are described as “surfable.” The combined energy is weak at 74, so it’s not going to be pumping, but it’ll be clean. The wind is the only thing making it a standout here. After that morning, it’s straight back to poor conditions. The Groyne is a fairly consistent reef, but this is a blank run that’s pretty normal for the area when the wind and swell don’t line up. The water temp is sitting at 69.1°, which is about average for the time of year – nothing weird there.
So, if you’re desperate, that Thursday morning session is the only one to pencil in. It’s a dawn patrol call for the cleanest conditions, but don’t expect much size. The rest of the 16 days? Leave the board in the car.

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.
