The Lowdown
G'day, Rusty here. Let's have a proper look at what The Groyne is offering up over the next couple of weeks. Honestly, it’s a bit of a rough stretch for a paddle. We've got a solid run of weak, wind-affected surf that’s going to test your patience. The only real glimmer of hope is a single, fleeting moment of glass.
We kick things off this Sunday, the 6th, and straight away it’s a tough one. Tiny, weak swell around 3 ft from the NNE with a shocking 5-second period. Combined wave energy is a pathetic 58, and with a cross-shore breeze, it’s just choppy and messy. Monday the 7th doesn’t get much better, though the energy bumps up to a moderate 134 on the morning with a 4 ft SE swell, but the cross-onshore wind ruins any chance of a clean wave. The whole first week is a write-off with scores of 0; the wind is either onshore or cross-shore, keeping the surface lumpy and the waves weak.
There’s a flicker of something special on Monday the 14th. The early morning session sees a tiny 3 ft swell from the E, but the magic is in the wind – it’s absolutely glassy, with just a 3 mph easterly breeze. The wave comment says "surfable waves but very ordinary conditions," but with glass, you never know what you might find. It’s a true low-tide diamond in the rough. But don’t get your hopes up for the rest of that day; by the afternoon the cross-onshore wind is back.
The second week starts to build in size, but the quality just isn’t there. Thursday the 17th sees a 7 ft SE swell with a solid 360 energy reading, but it's still poor. By the morning of Friday the 18th, the period jumps to a very long 12 seconds on a 2 ft SE groundswell, but the cross-shore wind keeps it from being anything special. For the rest of the outlook, it's a long, frustrating run of poor conditions right through to Monday the 21st, with swells dropping back to 1 ft and energy reading of just 33.
So, if you're desperate, keep your eyes on that Monday the 14th dawn patrol for a shot at something clean. But for the most part, The Groyne is in a funk right now.
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.
