The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on offer for The Groyne over the next couple of weeks. I’ll be straight with you – it’s a pretty quiet stretch, so don’t get your hopes up for anything pumping.
The Groyne is a reef setup that needs a decent push of swell from the southeast to get going, and we just aren’t seeing that magic combination for a while. The first few days are a write-off. Sunday the 30th of August has some chest-high swell at 5ft, but it’s coming with a short period of 6 seconds and a stiff SSE wind that’s cross-onshore, making it choppy and messy. The combined energy is moderate (197-216), but with that wind, it’s not worth paddling out. A real bummer.
We have a gap of a few days with no real recommendations. Monday the 31st and Tuesday the 1st are smaller and still blown out. The wind eases a bit, but the swell drops way down. You’re looking at maybe knee-high stuff with poor conditions.
The first real chance to get wet comes on Wednesday, the 2nd of September. The morning session is the pick: a small 3ft swell from the east with a 10-second period. The wind is light and cross-offshore from the north, which means clean, lined-up waves. The combined energy is weak (99), so it’s not going to be a big day, but it’s surfable. It’s an intermediate-level wave, so it’s not a beginner spot unless you’re comfortable.
Then, Thursday morning the 3rd of September is another one to look at. The swell is tiny at 2ft from the northeast with an 8-second period, but the wind is glassy – dead calm from the northwest. It’s clean as a whistle. The combined energy is weak (67), so you’ll be hunting for little peaks, but it’s the cleanest surf of the whole stretch. That’s our standout right there, despite the small size. The water temperature is about average for the time of year, nothing unusual.
After that, the swell just fades away. From Friday the 4th right through to the end of the 14th of September, there’s barely a ripple. We get a few fleeting moments of clean conditions, like on Sunday the 6th and Monday the 7th, but the swell is down to 1ft, which is barely a wave. The energy is in the teens (15-17), which is just about flat.
There’s a slight uptick on the 14th of September, with a 4ft east-northeast swell and a moderate 8-second period, but the wind is light cross-onshore, and the energy is 172. It’s still listed as poor conditions, so it’s not a goer.
Honestly, for this stretch, the best advice is to bob around on a longboard on the 2nd or 3rd if you’re desperate. Otherwise, it’s a waiting game. The waves are usually more consistent here, so I’d keep an eye on the forecast – it can change.
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.
