The Lowdown
Alright, let me have a look at what we've got coming up.
Honestly, it’s a pretty bleak run for the next couple of weeks. The pattern starts off flat and ugly and stays that way for a long stretch. We're looking at The Groyne (a reef break) and the finder shows no surf worth jumping for until we get into the second week.
Right from Monday, 7th September, through the whole first week, it’s just messy. Swells are tiny and short-period, mostly around 2 ft to 5 ft, coming in from the SE and ESE, but the wind is consistently cross or cross-onshore from the SSE and SE, blowing 6 to 22 mph, turning what little wave energy there is into chop. The combined swell energy barely breaks triple digits for days (59 to 112), and even when it does hit 160 on Thursday morning and 1141 on Thursday afternoon, the wind is howling at 22 mph, cross-shore, with rain. That Thursday afternoon 10 ft SE swell sounds big, but it’s a short 8-second period and the conditions are described as poor. It would be a washing machine. Honestly, that setup looks more interesting for kite surfing than paddle surfing – the wind and chop would make it a real handful.
We get a little glimmer on Tuesday, 15th September. Tuesday morning, the wind goes glassy – a light NNE breeze at 3 mph. The swell is only 2 ft from the NE with a 8-second period, and the combined energy is just 113, but it’s glassy. That is a rare moment of clean conditions. The forecast says "surfable waves but very ordinary conditions", so you might get a few little crumbly ones if you’re really keen, but don't expect much.
After that, it’s back to poor surf for the rest of the run. There’s another brief window on Thursday, 17th September morning, with glassy conditions again (ENE 3 mph) and a tiny 2 ft swell, but it’s even weaker with energy at only 58. The rest of the time is cross-onshore winds, choppy, and small. By Sunday, 20th September, the swell has dropped to 1.0 ft and 1 ft, and the energy is down to 13. It’s basically flat.
So, the only standout in the whole 16-day period is Tuesday morning, 15th September, and maybe Thursday morning, 17th September, for a quick, glassy paddle on tiny waves. But it’s not something to get excited about. The rest of the time, save your energy.

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.
