The Lowdown
Alright folks, it’s Rusty here. Let’s be straight with you – this 16-day window for The Groyne is a pretty grim run. There’s a massive gap right at the start with nothing worth paddling out for. From now all the way through to the 18th of September, it’s mostly onshore slop, choppy conditions, and small, weak waves. For over a week and a half, the best thing to do is leave the board in the car. The water temp is sitting at 70°, which is about average for the time of year – nothing special there.
The only glimmer of hope, and it’s a distant one, comes right at the tail end of the forecast. Saturday the 19th of September morning is the one and only standout. The Groyne is a reef break that’s fairly consistent, and this morning session sees a clean 3ft swell rolling in from the ESE with a period of 10 seconds. That’s a decent little groundswell, and the kicker is a light cross-offshore wind from the NNW. That’s going to groom the faces nicely. The combined wave energy is moderate (210), so there’s enough push to have some fun. This is a spot that can get crowded sometimes, but with how poor the rest of the run has been, it might be a bit quieter. The swell direction from the ESE is also a good match for the optimum direction from the SE. It’s not huge, but it’s the only clean, rideable wave on offer.
After that, the rest of the weekend and into the next week it fades right back into small, messy, and onshore junk. A few days of weak, short-period windswell from the north with cross-shore breezes aren’t going to save this outlook.
So, there you have it. A long, dry spell, and one morning on the 19th that looks promising. Don’t hold your breath for the rest.
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.
