The Lowdown
Alright, folks, Rusty here. Let’s be straight with you—this outlook for The Groyne is a tough one. We’re looking at a long 16-day window, and honestly, there’s not a single standout session that’s gonna get the heart racing. The surf is small and the wind just won’t play nice most of the time.
We’ve got a pretty bleak run for the first week. From Sunday the 26th right through to the end of July, it’s all poor surf conditions. The swell is tiny, mostly under 3 ft, and the wind is either cross or cross-on, keeping things messy. The combined wave energy is weak, sitting between 26 and 88 for most of that stretch. There’s a brief moment on Wednesday morning the 29th where it goes glassy—that’s a tease if I’ve ever had one—with a 2 ft easterly swell, but it’s short period at 6 seconds, so the waves will be soft and weak. The water temp is about average for the time of year, so nothing to write home about there.
The end of the first week into early August gets a little bump in size, but it’s not the kind of bump you want. On Friday the 31st, we see swell jump to 5 ft to 5 ft from the SE, but it’s still a short period windswell at 6 seconds, and the cross-on wind is 15 km/h. The combined energy climbs to 174–190, which is moderate, but the conditions are described as poor. That’s a no-go for a clean surf.
The second week is more of the same story. Monday the 3rd of August has a 2 ft swell but with a decent 12-second period, giving it a bit more grunt (energy up to 261), but the wind is a moderate 20 km/h cross-shore, and the wave comment is still poor. It’s frustrating because the swell is there, but the wind is ruining it. Tuesday the 4th of August morning is glassy again, with a 2 ft swell from the SE, but the period drops to 9 seconds and the energy is only 105—just ordinary waves.
The Groyne is a reef break, so when we do get a longer period groundswell, it can handle it better than a beach break. But the issue is the wind. From the 6th of August onward, we’ve got fresh breezes up to 35 km/h, and the swell is mostly short period and cross-on. The combined energy gets up to 233 on the 2nd of August and 261 on the 3rd, but without clean wind, it’s just a messy, choppy affair. Honestly, if you’re looking to paddle, you’re better off waiting for a better forecast. With the wind and the chop, this setup might be more interesting for the kite surfers than us.
We do have a couple of mornings with glassy conditions, but they’re paired with weak, small swell. The best of a bad lot is probably Wednesday morning the 29th of July—clean, glassy, and a 2 ft E swell. It’s only surfable, not great, but it’s the only time you might get a few fun ones without the wind messing you up. The other one is Tuesday morning the 4th of August, again glassy, but even smaller at 2 ft. That’s it. Nothing else in the 16 days is worth a special trip. The Groyne is fairly consistent, but this run is a real dud. It tends not to stay this poor for long, so keep an eye on the forecasts.
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.
