The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for The Groyne over the next couple of weeks.
Honestly, out the gate it’s a bit of a grim picture. We’ve got a long stretch of nothing good to start. The first real hint of any surf worth paddling for won't come until early September, so there’s a gap of several days with absolutely no recommendations. The pattern is dominated by a pesky cross-onshore wind that just won’t let up, and even when there is swell, it’s short-period, messy stuff. The combined swell energy for those first days is weak to moderate, reading up to around 293 (moderate wave energy), but it’s always paired with the wrong wind. It’s the kind of setup that would make a kite surfer happy, not a paddle surfer.
The standouts – and I use that term loosely – come on Thursday the 3rd and Friday the 4th of September. On Thursday the 3rd morning, we get a tiny window of glassy conditions at The Groyne, with the wind going glassy and a 2ft swell from the NE. It’s small, but that clean surface will mean a few fun little ones. The water temperature is 69°F, which is about average for the time of year, so nothing to worry about there. The combined energy is very weak at 64, so don’t expect any power. Friday the 4th morning is a repeat: glassy again, with the same tiny 2ft NE swell. These are the only two windows where you’ll find clean, surfable waves, though very ordinary in size.
Then on Saturday the 5th morning, we get another glassy moment with a touch more size – 3ft from the ENE – and the energy bumps up to a moderate 144. It’s still small and clean, but again, very ordinary. After that, the wind shifts back onshore and the swell stays small for days.
Later on, around Tuesday the 8th afternoon, the swell direction swings to SSE with a very long period of 13 seconds and combined energy of 344 (moderate wave energy). But it’s cross-onshore and choppy, so it’s a miss. The same goes for the bigger swells on the 9th, 10th, and 11th of September – they’re pushing over 7ft (too big for beginners, experts only in that range) with 7 to 8 second periods, but with relentless cross-onshore wind, it’s just a messy, lumpy, blown-out scene. The energy is strong to very strong, hitting 639 and 621 on the 11th and 9th, but it’s wasted.
So, your best bets are those glassy mornings on the 3rd, 4th, and 5th. Small, clean, and that’s about it. For the rest of the run, it’s a write-off for a paddle surfer.
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.
