The Lowdown
G’day, I’m Rusty. Let’s talk about what’s ahead at The Groyne. Honestly, looking through the whole 16-day window, it’s a pretty grim stretch for quality surf. There are no standout days with clean waves and favorable wind lining up properly. The first solid recommendation doesn’t really appear until well into the second week, so you’re looking at a long gap of poor conditions from now through most of the period.
From Wednesday the 9th through to Wednesday the 16th, it’s mostly a write-off. The swell is tiny, weak, or messy, with combined wave energy mostly sitting in the low double digits (45 to 72) – that’s weak energy. Winds are cross or cross-onshore nearly the whole time, producing choppy, lumpy surf. The water temperature is 70°F, which is essentially normal for this time of year (anomaly of -0.54°F). On Thursday the 10th, we see a spike in swell height up to 7 ft to 8 ft, and combined energy jumps to 308 then 702 (moderate to moderately strong), but it’s accompanied by 22 mph cross-onshore winds and rain showers. That’s a messy, blown-out situation – more for windsurfing or kiting than paddling into. The period is short (5 to 7 seconds), so the waves lack any real shape or power for a proper reef setup.
We finally get a small window of better potential on Thursday the 17th. The morning sees clear skies, a glassy wind state with only 3 mph from the ESE, and 2 ft swell from the east at 7 seconds. Combined energy is minimal at 63, but the conditions are clean. It’s surfable but very ordinary – tiny and weak. The wind is offshore from the west, so the face should be smooth, but the lack of size and energy means it’s barely worth getting wet for.
After that, from Friday the 18th onward, it’s back to small, onshore, or chop-affected surf. There’s a brief moment on Monday the 21st morning with glassy conditions and a 1 ft swell from the NE at 8 seconds, but the energy is just 33 – barely a ripple. Even the later days around Wednesday the 24th show a 7 ft SE swell with 341 energy, but the wind is cross-shore at 12 mph, making it a lumpy mess.
Bottom line: there’s no real standout session in this outlook. The only half-decent chance is Thursday the 17th morning if you’re desperate for a clean but tiny paddle. For the rest of the run, save your energy and wait for a better forecast.
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.
