The Lowdown
Alright, Rusty here again, this time in feet and miles per hour. Let’s get into it.
Right from the get-go, it’s a pretty flat start. From Wednesday the 26th of August all the way through to Sunday the 6th of September, the surf is mostly poor or ordinary. Small waves, weak energy, and messy winds. Swell heights sit between about 2ft and 3ft, with combined energy in the low to moderate range (117 to 221), but the period is short—only 6 to 8 seconds. Winds are mostly cross-shore or onshore, keeping things choppy. There’s a glimpse of hope on Wednesday morning the 26th and again on Wednesday the 2nd of September where the wind goes glassy or light offshore, but the swell’s still small at around 3ft. Not exactly firing.
The end of August is a big write-off. Thursday the 27th through Saturday the 29th is gusty southerlies and messy. Sunday the 30th of August sees a bump to 6ft to 7ft, but with a super short 6-second period and fresh cross-shore winds, it’s just a lumpy, bumpy mess. That setup with side-shore wind and biggish short-period swell is probably better for kite surfing than paddling.
Now, here’s the one you want. On Monday the 7th of September morning, it finally comes together. The swell is 4ft from the SSE, period 8 seconds, and the wind swings offshore from the NNW at 9 mph. Combined energy hits 275 (moderate), and it’ll be clean. That’s the standout session of the whole 16 days. The Groyne is a reef setup and likes SE swell best, but SSE is close enough, and with clean conditions it’ll be worth a paddle.
After that, the second week drops right back down—tiny 1ft to 3ft swell and mostly onshore or cross-winds again. There’s a glassy morning on Thursday the 10th of September with 3ft east swell, but nothing to write home about.
So mark your calendar for Monday the 7th of September morning. That’s your best bet. Water temp is about 68°, a little below average for this time of year, so grab a spring suit.
Rusty.

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.
