The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking over the next couple of weeks.
Honestly, it’s a pretty grim stretch ahead. The Groyne is a reef setup and it’s exposed to the swell, but the problem is the wind just won’t play ball for most of the period, and the swell is mostly short-period, weak, and messy. We’re kicking off with nothing much on offer, and it’s going to be a long, quiet run.
The first couple of days are a write-off. Saturday afternoon sees a tiny 2ft swell from the NNE with a shocker of a 4-second period, cross-on wind at 12 mph, and wave energy barely registering (37). That’s a big fat zero.
Sunday morning on the 6th of September is the first time we get a “surfable waves but very ordinary conditions” call. Swell is still small at 3ft from the NNE, period a weak 5 seconds, but the wind swings cross-offshore from the NNW at 9 mph, making for clean conditions. The combined energy is still low (56), so it’s not going to be thrilling, but it’s the best of a bad bunch in the first week. You could get a few grovelly ones if you’re desperate.
After that, it’s a desert. From Sunday afternoon right through to the 13th of September, everything is scored zero – poor surf conditions with cross-onshore or onshore wind, lumpy chop, and tiny, weak swell. There’s a brief glimpse on the morning of Monday the 14th of September – glassy conditions with an ESE wind at just 3 mph, swell 2ft from the ENE with an 8-second period. That’s clean but incredibly small (energy 55). You’d need a log and low expectations.
The one standout, if you can call it that, is Wednesday morning on the 16th of September. The swell jumps to 6ft from the SE, with a 7-second period and the combined energy finally kicking into life (327). That’s moderate energy. But the wind is a cross-shore from the S at 12 mph, so it’s going to be a bit lumpy with a cross-chop. At 6ft, it’s getting a bit much for beginners, but for an intermediate on a reef, it could offer some fun if you can work around the wind. The swell direction (SE) matches the optimum direction for The Groyne, which is a positive. Still, it’s not clean, and you’ll be fighting the chop. It’s the only real pulse in the whole 16-day outlook.
The last few days (17th to 20th September) fade back into tiny, weak, and windy conditions. Nothing worth getting excited about.
So, to sum it up: the best chance all period is the clean but tiny window on the morning of the 6th of September, and the biggest, most energetic pulse on the morning of the 16th of September (6ft SE, energy 327, moderate cross-shore wind). Neither is a classic, but that’s the pick of a very poor litter.
The water temp is sitting around 69°F, which is a touch cooler than usual for this time of year (anomaly -1°F), so average enough.
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.
