The Lowdown
G'day, Rusty here. Honestly, this is a tough stretch for us at The Groyne. The whole 16-day window is pretty flat and ordinary, so I'm not gonna sugarcoat it—there's no standout session to get excited about. The water's sitting at 68°, which is a bit colder than normal for this time of year, so you'll want a decent spring suit.
Let's walk through it. Tuesday the 25th starts with a tiny 3 ft swell from the ENE, period a short 8 seconds, and the energy is weak (114). Morning glass-off is nice but the waves are pretty average. That afternoon, the wind swings cross-on and it's game over. Wednesday the 26th morning has a clean 3 ft wave with a light offshore, but again, tiny and weak energy (99). Not worth rushing out.
From Thursday the 27th through to Monday the 31st of August, it's a write-off. The wind is onshore or cross-shore, building from 9 mph up to 19 mph, with swell bumping up slightly to 5 ft–6 ft on the weekend but with a terrible 6-second period and lumpy, choppy conditions. That's more of a kite-surfing setup than paddle surfing, if you ask me.
Tuesday the 1st of September offers a brief clean-up with a light cross-off wind and 4 ft swell, but the period is still short (6 seconds) and the energy is moderate (174). It's surfable but very ordinary. Wednesday the 2nd morning is glassy with 3 ft, and Thursday the 3rd morning is glassy with just 2 ft. The period is creeping up to 9–10 seconds, but the swell is too small to get excited.
Friday the 4th of September morning you'll see a weird 1.0 ft swell with a very long 21-second period (energy 139). That's a long-period groundswell, but it's tiny and will break too straight at a beach break—best left for a reef or point, but we don't have that here. The rest of the first week of September is a mix of tiny waves and poor wind, with the 6th and 7th being particularly weak (energy in the 40s–70s).
The final few days, 8th and 9th of September, see a little bump in size to 4 ft–5 ft but with short periods (5–6 seconds) and lumpy cross-shore winds. The 9th morning has a clean 4 ft wave with a light cross-off, but it's still just "surfable" and nothing special.
Bottom line: No standout days. A few mornings might be worth a quick paddle if you're desperate, but there's nothing that'll make you want to call in sick. The forecast can always change, but for now, this stretch is a dud. Keep an eye on the charts, mate.
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.
