The Lowdown
Alright folks, Rusty here. Let's take a look at what's on the table for The Groyne over the next couple of weeks.
Honestly, the outlook is a bit of a struggle. We’re looking at a 16-day window, and there’s a real drought of any quality surf here. The Groyne is a reef setup that usually likes some SE swell, but we just aren't getting it. There are barely any windows at all where it’s even worth paddling out.
The story kicks off on Wednesday the 2nd of September, and it’s grim from the start. The swell is tiny at 2 ft from the east, with a pathetic energy reading of just 65 and a short period. To make matters worse, the wind is a cross-on NNE breeze at 12 mph. It’s choppy, messy, and I wouldn't bother. This poor run continues day after day. We get a mix of tiny swell (1.0 ft to 1 ft) and unfavourable cross or onshore winds. Thursday the 3rd and Friday the 4th offer nothing.
There’s a glimmer on Saturday the 5th in the afternoon when the swell bumps up to 4 ft, but it’s from the NNE with a terrible 5-second period and lumpy 19 mph cross-winds. The energy is moderate (107), but the quality is non-existent. That theme holds for the whole first week.
Even when we get a glassy morning on Wednesday the 9th with a light easterly wind, the surf is only 2 ft with ordinary conditions. It’s surfable, but barely. The wind stays messy or onshore for days after that. There’s a notable spike in energy on Friday the 11th of September, with swell hitting 7 ft from the ESE and energy jumping to 364 – that’s a lot of power. But the period is only 7 seconds, and it’s accompanied by rain showers and a choppy cross-onshore wind at 16 mph. That’s sloppy, powerful close-out material and definitely one for experts only.
The only other faint hope is another glassy morning on Thursday the 17th of September. The swell will be 3 ft from the ENE with an 84 energy reading. It’s a clean 3 ft wave with no wind. It’s still weak and short-period, but it’s the best we’ll see.
There are no standouts here. The lack of consistent, quality surf makes this a real downer. Conditions are consistently poor, with the wind almost always onshore or cross-shore and the swell never really aligning to produce a clean, workable wave. If you’re desperate, the glassy Thursday the 17th is your best bet, but keep expectations low.
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.
