The Lowdown
Righto, Rusty here. Let’s talk about The Groyne over the next couple of weeks.
Honestly, it’s a tough stretch. We’ve got a 16-day window ahead of us, but the first real chance of anything surfable doesn’t pop up until Wednesday, September 9, and even then it’s a marginal call. Before that, we’re looking at a solid run of poor conditions. From Friday the 4th right through Tuesday the 8th, the swell is tiny, the wind is mostly cross-onshore or cross, and the energy is weak – we’re talking combined wave energy down around 2 to 11 (kilojoules per foot squared). Not worth paddling out for.
The first little glimmer comes on Wednesday morning the 9th. The swell ticks up to 3ft from the southeast with a period of 10 seconds, and the combined energy jumps to 272 – that’s moderate energy. The wind is a light cross-shore breeze, which will keep things from getting too choppy. But the report says “marginal surf forecast or questionable tide conditions”, so temper your expectations. This one’s a maybe, not a goer.
Then we drop back into poor conditions again until Monday the 14th. On Monday afternoon, a 6ft SE swell rolls in with 238 energy, but the wind is onshore and it’s still flagged as poor. Tuesday morning the 15th looks slightly better – 6ft from the SE, 296 energy, and the wind is a light cross-onshore. This is the best of a rough bunch. It’s got some size, but it’s blowing a bit on it. Still, if you’re keen, this is your window. After that, it’s back to small, choppy, and lumpy right through to the end of the period.
The Groyne is a reef break, exposed to the swell with an optimum direction from the southeast. The water temp is 69°, which is about average for this time of year – no anomaly to speak of. Crowds can pop up here sometimes, but in this forecast, you won’t have to fight for waves.
So, to be clear: there’s no standout session here. If I had to pick one, it’s that Tuesday morning the 15th – the biggest swell and the most energy, but the wind isn’t doing us any favours. The rest is mostly a write-off.
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.
