The Lowdown
Alright folks, Rusty here. Let's have a look at what The Groyne has in store for us over the next couple of weeks. Straight up, I gotta be honest with you – it's a tough watch for most of the run. We're looking at a long stretch of small, weak, and messy conditions, so don't go getting your hopes up too high.
The forecast kicks off with nothing worth paddling out for. Sunday the 23rd and Monday the 24th are just poor – onshore winds and weak, short-period swell. You're better off staying on the beach. There’s a bit of a gap here before we see anything surfable.
The first real chance to get wet comes on Tuesday morning, the 25th of August. It's not going to be anything special, but for a few hours we get some glassy conditions with the wind dropping to nothing. The swell is tiny at about 3ft from the ENE, with a short 8-second period and low energy (116). It's surfable but very ordinary. The afternoon gets choppy again.
Wednesday morning the 26th is another marginal window. We've got a light offshore wind from the SW, keeping it clean, but again the swell is weak – 3ft from the E (114). It's small, slow, and pretty average.
After that, we go back into a long stretch of nothing. From Thursday the 27th right through to the end of the month and into early September, it's all poor surf conditions. The wind is mostly cross or cross-onshore, and while the swell tries to pick up a little around the 27th and 30th of August, it's just too messy. The energy does jump to moderate levels like 349 and 387, but the wind kills it. The swell direction from the ESE and SE isn't ideal for the reef either.
We get another tiny, clean window on Wednesday morning, the 2nd of September. Again, glassy conditions, but the swell is a piddly 3ft from the E with a slightly better 9-second period (136). It's another one for the small-wave crew only.
There's another glassy morning on Friday the 4th of September, with a 3ft ENE swell (120), but it's followed by even smaller surf. By the weekend of the 5th and 6th, the energy drops right off, down to 30 by Sunday, and the swell is barely 2ft. It's all looking pretty bleak.
The very last entry we've got is Monday morning the 7th of September. It's glassy again, with a tiny 2ft NE windswell and a short period of 5 seconds (57). Surfable but very ordinary.
Honestly, there isn't a single standout session in this whole 16-day window. The best you can hope for is a quick, small, clean wave on one of those glassy mornings, but it's going to be inconsistent and weak. If you've got a longboard and no expectations, you might find something. Otherwise, this is a period to leave the boards in the shed.
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.
