The Lowdown

G’day, Rusty here. We’re looking at the next couple of weeks at The Groyne and honestly, the forecast is a tough one to get excited about. There are patches of real glassy conditions, but the swell is small, and the quality is nearly always ordinary. The surfable windows are short and far from classic.

The water is sitting at 68°, bang on average for the time of year, so no surprises if you’re in a spring suit.

Monday the 24th is a write-off. Rain showers and onshore wind with a weak 3 ft swell from the ENE and a period of 7 seconds. Combined energy is low at 114, and conditions are poor. Not worth paddling out.

Tuesday the 25th morning is the first real bright spot. We’ve got glassy conditions with no wind, and a 3 ft east swell, period 8 seconds. Combined energy is still modest at 139, but the clean surface will make a huge difference. It’s surfable, but nothing special. Tuesday afternoon the breeze picks up to 9 mph from the northeast, cross-onshore, and the quality drops straight back.

Wednesday the 26th morning gives us another glassy window. Swell drops to 3 ft, still from the east, 8-second period, and energy down to 101. You can catch a few, but it’s very ordinary. By lunch the wind is up again.

Then from Thursday the 27th through to about Monday the 2nd of September, it’s a long stretch of poor conditions. Winds are mostly cross-onshore or onshore, moderate to fresh breezes. Swell bumps up – on the 28th Friday morning we get 4 ft ESE with an energy reading of 341, but the wind is cross-onshore and the period is short at 7 seconds. Poor surf. By Sunday the 30th afternoon, swell hits 5 ft from ESE, period only 6 seconds, and it’s messy. That combined energy of 267 sounds moderate, but it’s not the kind of energy you want – it’s just wind chop.

Tuesday the 1st of September is another one to skip. Swell up to 6 ft from the east, period 7 seconds, and onshore ESE wind at 6 mph. The energy is pushing 402, but the quality is still poor.

Wednesday the 2nd of September morning is marginal at best – 5 ft ENE, 8 seconds, cross-shore wind. It’s surfable if you’re desperate, but I’d wait.

Now, the real standout in this whole 16-day window comes on Thursday the 3rd of September and Friday the 4th of September mornings. Thursday morning: glassy, no wind at all. Swell is 4 ft from ENE, period 8 seconds. Combined energy is 187 – moderate and cooked up nicely. It’s surfable, clean, and easily the best conditions of the whole run. Friday morning the 4th is even better for the glassy surface, though the swell is dropping to 3 ft with the same east-northeast direction. Still clean and rideable.

Saturday the 5th morning also has glassy conditions, but only 2 ft of swell, energy just 86. It’s small but clean if you’ve got a longboard.

After that, into the second week, the surf fades. Winds turn northeast to north, swell stays under 3 ft, and there’s no real energy to write home about. Crowds can show up at The Groyne sometimes, especially when it’s the only thing showing, but with the quality this low, I wouldn’t expect a circus.

So if you want the best of a bad run, lock in Thursday the 3rd of September morning or Friday the 4th of September morning at The Groyne. Glass, clean lines, and the only session worth planning around. The rest? A lot of looking at flat water from the car park.

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.
