The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Honestly, the outlook for The Groyne is a tough one. Over the next 16 days, there’s just not a single session that’s going to get the heart pumping. The whole period is a bit of a write-off for paddle surfing, I’m afraid. The swell is mostly small, weak, and the wind is never playing ball for clean conditions. You’ll see a bit of size come in around the second week, but it’s always carrying that onshore or cross-onshore wind, making it messy and lumpy.
We start off with a clear Thursday morning, the 3rd of September. Swell is a tiny 1ft from the east, with a period of 9 seconds. The wind is a light cross-off from the NNW, so the conditions are clean, but there’s just no energy to work with – the combined swell energy is only 33. It’s a “poor surf” call, and we move on.
Friday the 4th and Saturday the 5th are similar story: small, weak swell, never over 4ft, and the wind is cross or cross-on. The paddle out might be easy, but you’ll be bobbing around on nothing.
The first real sign of any power comes on Tuesday the 8th of September. The morning sees a 6ft swell from the SSE, period 6 seconds, with a moderate cross-shore wind. The combined energy jumps to 287 (moderate), but the quality is still poor. That afternoon, the swell bumps up to 7ft, but it’s a cross-on, choppy mess. It’s the same story into Wednesday the 9th – a 4ft SSE swell, but the wind is cross, and the energy is only 112. The afternoon does see a 3ft swell from the SE with a period of 11 seconds, giving a moderate energy of 252, but it’s a direct onshore wind. These long-period swells (11 seconds) are better off at a point or reef, but with the wind on it, The Groyne is just going to be a bumpy, blown-out affair.
The biggest swell of the window hits around Thursday the 10th and Friday the 11th of September. We’re looking at 7ft to 8ft, with the energy climbing to 755 (strong) on the Friday morning. That’s a lot of water moving, but it’s all coming from the SE and ESE, with a strong cross-on wind. For a reef break, that’s a recipe for close-outs and a washing machine. The period is only 7-8 seconds, so it’s a short-period wind swell, not a clean groundswell. This is one for the experts only, honestly, and even then, it looks more like a kite-surfing day than a paddle-surfing day.
The final week from the 14th sees the swell drop back down. The 16th of September brings a 4ft swell, but a strong breeze from the SSE at 25 mph will make it a total mess. The period is 7 seconds, so no point holding your breath.
The water temperature sits at around 69°F, with a slight anomaly of -2°F, meaning it’s a touch cooler than average for this time of year, but not crazy.
So, what’s the best on offer? There isn’t a standout. The closest we get to a window of opportunity is the morning of the 9th of September, with the 4ft swell and the light cross-shore wind, but even then, it’s a poor surf call. The 8th of September has size, but the quality is non-existent. This is a blank run, and for this area, it’s not unusual to see a stretch like this. Forecasts can change, but for now, keep the board in the car and check back later.
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.
