The Lowdown
Alright, Rusty here. Let's break down the next couple of weeks.
First up, we've got The Groyne, a reef break. The water's sitting at 68.4°, which is a bit colder than the usual for this time of year. To be honest, the outlook is a bit of a flat spell for a while. There's nothing worth getting excited about for the first several days. The swell is tiny, with energy readings barely scraping into double digits – a weak 63 (combined energy) on Wednesday the 2nd, and it just gets smaller from there. Winds are a mess, mostly cross or cross-onshore, so the conditions are ordinary at best.
We've got a big gap of quiet, poor surf until we hit the second week. The first real sign of life comes on Friday the 11th of September, but it's not the kind of life you want. The swell jumps up to 7.9ft from the ESE, but it's a short period of 7 seconds, and the wind is a stiff cross-onshore. The combined energy hits a strong 571, but the surf is going to be a choppy, lumpy mess. That's a no-go for paddle surfing – that kind of wind and size on a beach setup is more for the kite crew.
The Saturday the 12th is similar, with 7.2ft from the E, energy at 570, but still cross-onshore. It's a bit of a circus. The morning of Sunday the 13th has 7.2ft from the E, a light cross-onshore, and the energy is still strong at 527. It's a marginal call, but not a standout.
The closest thing to a decent window might be the morning of Wednesday the 17th of September. Swell is a small 3ft from the ENE, period is a short 7 seconds, but the wind is glassy – dead calm. The energy is moderate at 130. It's clean, but the swell is tiny. There's no big, clean swell on offer here. The best recommendation is that glassy morning for a small wave session, but don't expect any barrels.

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.
