The Lowdown
Alright, Rusty here, and I’ve got my eyes on the charts for the next couple of weeks. To be honest, it’s a pretty grim run for us. The Groyne is a reef setup, exposed to the swell, and it’s happiest with a swell from the SE. The water’s around 68°, which is a bit colder than what we’d usually expect for this time of year, so you'll want that extra layer.
The first real chance to get wet doesn't look like it's going to be much of a chance at all. We’ve got a long stretch of poor-to-ordinary conditions here. From Saturday the 22nd right through to the end of the month, the surf quality is just terrible. The wind is mostly cross or cross-onshore, the waves are small and weak, and the combined energy is low, barely pushing into triple digits (113-126). It’s just not doing anything for us.
Things perk up a tiny bit around Tuesday morning, the 25th of August. We get a glassy session with the wind dropping away to nothing, and a small 3ft swell from the ENE. The energy is still modest (112), but it’s clean. That’s the best we get for the first week, but it’s only for a couple of hours before the wind swings around and ruins it.
The next glimmer comes on Wednesday morning, the 26th. A light offshore wind from the west (3 mph) keeps things clean, but the swell is only 3ft from the E, with a weak 7-second period and low energy (103). It’s surfable, but it’s not a standout.
The second week is more of the same struggle. The morning of Tuesday, the 1st of September, is glassy calm with a 2ft swell from the east, but it’s weak (129 energy). Then Wednesday morning, the 2nd of September, sees another shot of clean conditions with a light offshore (3 mph) and a 3ft ENE swell (119 energy). It’s not going to blow your mind.
Look, there’s *nothing* here that I’d call a true standout. The biggest swell we see is a 6ft from the SE on Monday the 31st of August, but it’s a short-period windswell (6 seconds) and the wind is cross-onshore and messy. The energy is moderate (284), but the conditions are so poor it’s not worth the paddle.
If you’re desperate, the only windows are the glassy mornings on the 25th of August, the 1st of September, and the clean offshore mornings on the 26th of August and the 2nd of September. Even then, it’s knee-to-waist high at best. It’s a tough forecast, folks. The Groyne just isn’t getting the goods.
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.
