The Lowdown
Alright, Rusty here again. Let’s break it down in feet and miles.
First off, I gotta be straight with you. The forecast for our local reef, The groyne, looks pretty grim for the first week and a half. We’re looking at a dry spell with no real surf to speak of from Thursday the 30th of July all the way through to the weekend. The wind is a mess – cross and cross-onshore – and the swell is a jumbled mess of short-period, low-energy windswell. The combined energy is weak, hanging around the 50 to 79 mark, and it’s just producing poor, choppy conditions. It’s a kite-surfer’s paradise with that strong cross-shore wind, but not much for us paddle folk.
We finally get a tiny window of hope early on Monday the 3rd of August. The morning sees a light southerly breeze cleaning things up, with a 2ft swell from the SE. The period jumps to 12 seconds, which is proper groundswell, and the energy ramps up to 236. It’s small, but it’ll be clean. The water temp is about average for this time of year, so a spring suit is fine.
The real standout is way down the line, on Friday the 14th of August. The morning is looking like the best bet of the whole 16-day window. We’ve got a light NNW breeze, glassy conditions, and a long-period SE swell at 14 seconds. The swell is only 3ft, but the combined energy is a solid 392, which is big for such a small wave. That’s a lot of push. The offshore wind from the NW will have that reef lining up beautifully. Keep in mind this is a long-range call, so it’s promising but not locked in yet. If it holds, get down there early.
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.
