The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for The Groyne.

To be straight with you, the next week and a half is looking pretty grim. We’ve got a long stretch of poor conditions. From Thursday the 27th of August all the way through to the morning of Wednesday the 2nd of September, it’s a write-off. The wind is all over the place – mostly cross or cross-on – and it’s choppy. The swell is small, around 2ft to 5ft, and that energy is weak to moderate at best (energy readings between 109 and 221). The period is short too, mostly 6 to 8 seconds, so no power behind it. Don’t bother paddling out.

Now, here’s a little glimmer. On the morning of Wednesday the 2nd of September, things finally calm down. The wind goes glassy – dead calm – and the water turns to glass. It’s a reef break so it needs a clean face, and that morning it’ll have it. The swell is tiny though, only 2ft from the east with a 10-second period. That’s a longer period, which means a bit of shape, but it’s small. The energy is weak (73). It’s surfable, but very ordinary. If you’re desperate for a slide on a longboard, that’s your window. The water temperature is about average for this time of year, nothing unusual there.

After that, the wind picks up again. Thursday the 3rd and Friday the 4th are back to cross-on breezes and choppy water. Swell stays small, around 2ft to 3ft, and the period drops back to 8 seconds. Not worth it.

Saturday the 5th of September morning sees a clean-ish cross-shore wind from the north at 9 mph, with 3ft east-northeast swell. Still small and weak (111 energy). The afternoon gets windier. Sunday the 6th of September is actually interesting for a change – a cross-offshore wind from the north-northwest. The morning has 2ft from the east-northeast (82 energy) and the afternoon bumps up slightly to 2ft from the east with a 9-second period (106 energy). Both are described as “clean” in the data. For a reef break, that cross-offshore flow will tidy things up nicely. The waves are still tiny, but if you’ve got a log and you want a few clean little runners, that Sunday afternoon is your best bet in the whole outlook.

After that, from Monday the 7th of September, it’s back to small, choppy, and poor. A couple of afternoons mid-week show a slight bump in size – Tuesday the 8th afternoon has 5ft from the northeast but with a shocker 5-second period and cross-on wind. That’s just bumpy junk. Thursday the 10th morning has 4ft from the east with a 7-second period and light cross-on breeze – still poor.

Honestly, there’s no standout session here. The only two that are worth a mention are the glassy Wednesday morning (2nd Sept) and the clean Sunday afternoon (6th Sept). They’re not big, they’re not powerful, but they’re the cleanest of a messy bunch. Don’t expect any barrels.

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.
