The Lowdown
Alright folks, Rusty here. Let's have a look at what we've got for The Groyne over the next couple of weeks.
Well, I gotta be straight with you. This is a tough outlook. We’re looking at a solid two weeks of pretty much nothing worth paddling out for. The first recommendation doesn't show up until a full two weeks from now, on the 18th of September. That’s a long, dry spell.
The Groyne is a reef setup that likes the swell from the SE, and we just aren't seeing any decent windows. The first half of the period is all tiny dribble and junk wind. There’s a bit of a pulse of energy building around the 8th of September, with combined swell energy hitting 396 (moderate wave energy) on the Tuesday afternoon and swell heights up to 7ft, but the wind is a fresh cross-onshore at 19 mph, ripping the place apart. That’s messy, lumpy, and not worth your time.
Then it gets real interesting around the 10th of September, with the swell energy climbing to 304 (moderate wave energy) and 6ft of swell from the SE, but again, we get hammered by a strong breeze at 25 mph and rain. That’s less surfable and more of a “watch from the car park” kind of day.
After that, it’s more of the same: moderate to fresh onshores and choppy conditions right through until the 17th. The water temp was around 69°, which is close to normal for this time of year, so no surprises there.
Now, the one small glimmer in all this comes on Friday, the 18th of September, in the morning. We get a 5ft swell from the SE, and for the first time in ages, a light offshore wind from the W at 6 mph. That makes things clean. The combined swell energy is 125 (moderate wave energy), but the period is a short 5 seconds, so it’s not going to have much grunt. It’s surfable, but very ordinary. The afternoon on the same day sees the swell bump up to 7ft from the SE with energy at 421 (still moderate wave energy), but the wind swings cross-shore and the conditions get lumpy again.
So, if you absolutely have to get wet, the morning of Friday the 18th of September is your only real shot. It’s not a standout by any means, but at least it’s not a total write-off. For the rest of the 16 days, leave the board in the garage.
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.
