The Lowdown
Alright, Rusty here. Let's cut through the noise on this one.
Honestly, the next sixteen days are a tough watch. The groyne's a reef break, and it needs some love from the ocean, but we're not getting much. The first week is basically a write-off. From Tuesday the 1st through to the 8th, we’ve got tiny waves and messy wind. The combined swell energy barely gets out of the weak range (values like 159, 85, 63) – that's knee-high slop at best. The water's a bit colder than usual at 68°, but that's not the story here; the lack of any real swell is.
There is one day that perks up an eye – Friday, September 11th. The morning is tiny with a 1ft swell from the ESE and a 13-second period, clean but weak. The real event is the afternoon: a 2ft swell from the SE, but with a very long 16-second period. That’s real groundswell energy, pushing a combined energy of 294 (moderate wave energy). That's the only standout in the whole window. The power and shape will be there, but it's a shame the wind comes onshore from the SE at 16 mph, making it choppy. For a surfer who doesn't mind a bumpy ride for some juice, that's your one shot.
The rest of the second week is a lot of the same – a few pulses of moderate energy (like on Saturday the 12th and Sunday the 13th with combined energy of 121 and 125), but always with a cross or cross-on breeze messing it up. By the 15th and 16th, it's back to tiny and weak. The only session with any real promise is that Friday afternoon, September 11th. It's not perfect, but it's the only time the ocean has any real intention to offer a wave.
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.
