The Lowdown
Alright, Rusty here, let’s have a look at what’s on the cards for The Groyne.
Straight up, it’s a pretty quiet stretch ahead. The Groyne is a reef break that’s fairly consistent, but the next couple of weeks look like a long, flat spell. There’s no real surf on offer for the first few days, and the rest of the forecast is mostly a write-off for anything decent. You’re looking at a gap of around two weeks with no real standouts.
The first bit of hope comes late on Monday, 14 September. The morning is still poor, but by the afternoon there’s a small window. The swell is tiny, only about 2ft from the east at 8 seconds, with a combined energy of just 51 (weak). The wind is light and cross-off from the SSW, so the surface will be clean. It’s surfable, but only just, and very ordinary. Water temperature is about average for this time of year.
The only other time things pick up a little is Tuesday, 15 September. The morning brings a bit more size, around 5ft from the ESE, but the period is a short 5 seconds, so it’s weak and messy. Combined energy is 113 (moderate), but the wind is cross-shore, not helping. The afternoon is similar, 3ft, cross-on wind, and a bit choppy. Not a great look.
Honestly, if you’re desperate, the cleanest window is that Monday afternoon, but it’s tiny. For the rest of the forecast, it’s mostly poor conditions, with small swell and cross-shore or onshore winds. Not much to get excited about.
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.
