The Lowdown
Alright friends, Rusty here with a look at the forecast.
To be honest, this one is a tough read. We’re staring at a massive gap at the start with no worthwhile waves. That dry spell runs from the beginning right up until the 29th of September. Not a single standout in there.
From the 16th right through the 28th of September, it's pretty much a disaster. Sure, there’s some size, like a 2.4m bump on the 16th afternoon, but it’s completely wrecked by strong cross-onshore winds making it choppy and lumpy. You get pulses of 1.8m with an 8-second period, like on the 17th morning, but the wind just kills it every time. For this beach-and-reef setup, with that wind and swell, it’s honestly more of a kitesurfing scene than a paddle spot.
The one and only bright spot shows up on Tuesday the 29th of September. The morning session is the play. We’re looking at a 1.4m swell from the east, a reasonable 8-second period, and moderate energy (253). The wind is the hero here, a light 5 km/h WNW cross-offshore breeze that will have the lines clean and glassy. The groyne is a reef, and this east swell is close to its preferred southeast direction. It’s a short window though; by the afternoon the wind switches and the quality drops. The water itself is seasonably average for now.
So, one crisp morning after a long dry spell. That’s the call.
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.
