The Lowdown
Alright, Rusty here. Let's break down the local surf.
First thing's first, it's a long, dry spell we have to get through. For over two weeks, it's going to be pretty ordinary. The wind is going to be cross-onshore most of the time, making a mess of what little swell there is. The wave energy is mostly on the weak side, with a reading between 41 and 821. Don't expect any good paddle surfing for a while.
For the first week and a half, it's all about that onshore wind and choppy conditions. The swell comes from the SE and ESE, with wave heights from about 2ft up to 8ft, but the wind is just trashing it. Starting Thursday the 10th, we get a 8ft to 8ft SE swell (energy at 426 and 821), but that fresh SSE wind makes it a lumpy mess. At that size with that wind, you'd be better off with a kite. The water temperature is about normal for the season.
The only real light at the end of the tunnel comes around Thursday the 24th of September. The morning shows a 7ft SE swell (energy at 392) with a gentle cross-shore breeze. That’s the change we’re after. The swell is coming from the right direction for The Groyne. The period is only 6 seconds, so it’s a short-period swell, but the cleaner conditions might actually make it workable. Then Friday the 25th morning looks even better: a 8ft SE swell (energy at 703) with that same gentle cross-shore wind. It’s going to be big – over 5ft – so it's for experienced surfers only. Crowds are listed as "sometimes", so you might share it with a few others, but it won't be packed.
That’s the window. The mornings of the 24th and 25th of September. Everything else is a washout. Keep an eye on that.
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.
