The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this is a tough stretch for The Groyne. We’re looking at a real dry spell coming up, so don’t get your hopes up.
The forecast shows a long gap with hardly anything worth paddling out for. The first couple of weeks are looking pretty grim, with mostly small, weak swell and rubbish wind. The first time we even see a hint of something surfable is on Wednesday morning, September 2nd. The swell is tiny at 2 ft from the east, but the wind swings light from the NNW, giving us a clean, cross-offshore breeze. It’s surfable, but very ordinary – the wave energy is weak (64). It’s about as small as it gets. After that, we’re straight back into the doldrums with days of tiny, choppy junk through the first week of September.
We finally get a bump in size on Friday afternoon, September 11th, with a 6 ft SE swell rolling in. That’s the biggest we see, and the combined energy jumps to strong (324). But don’t get too excited – the wind is howling onshore from the ESE at 12 mph, making it a choppy, messy onshore mess. That’s really only one for the experts on a good day, and this isn’t one. For the rest of the period, it’s just more of the same: poor conditions, cross-onshore winds, and weak energy levels. The water temp is sitting at 69° with a slight anomaly of -2°, so it’s a little cooler than average for this time of year, but nothing crazy.
Honestly, there’s no standout session in this whole outlook. The only window to maybe get wet is that Wednesday morning, September 2nd, for a tiny, clean wave if you’re desperate. Otherwise, it’s a long stretch of flat to poor conditions. We’re looking at a blank run that lasts for most of the first week and only offers very marginal options after that.
Stay patient, lads. The ocean will come good again.
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.
