The Lowdown

Alright, Rusty here. Let's take a look at what's on the menu for The Groyne.

Overall, it's a pretty quiet stretch on the whole. The next couple of weeks aren't looking like a classic run; we're in for a lot of small, choppy days with the wind playing havoc. There's a couple of windows where it could clean up, but you've got to be patient.

The standout window is actually Tuesday morning, August 25th. It's not a massive swell, but it's the best we've got. The Groyne is a reef setup, and we're seeing a clean 3ft from the ENE with an 8-second period. The real kicker is the wind: glassy. Dead flat calm. That makes for a rare, clean session where the waves will have some shape. The energy is moderate (114), so there's enough to push you around. This is a morning mission for the dedicated local.

After that, things get messy. From Tuesday afternoon right through to the end of the month, the wind swings around and gets onshore or cross-shore, mostly from the SSE or SE, and it's just rough. The swell stays small, between 3ft and 4ft, and the period drops to 6-7 seconds, which is weak, short-period windswell. The energy jumps up a bit, but it's all chop. It's not worth paddling out for.

Saturday, August 30th sees a bit more size, up to 5ft, but again it's onshore from the SE with a 6-second period. The energy is up to 217 (moderate), but it's a lumpy, windy mess. That's a day for the kites, not the surfboard.

Heading into the first week of September, it's much the same story. We get a little window on Wednesday morning, September 2nd, with another glassy session. The wind is calm from the NNW, and the swell is a small 4ft from the ENE with an 8-second period. The energy is moderate (161). It'll be rideable and clean, but don't expect anything big. It's a better option than most, but it's still small.

The rest of the first week of September is a write-off. The wind is mostly cross or onshore, and the swell is either small or short-period. There's a brief clean moment on Monday morning, September 7th, with a 3ft swell and a light offshore, but it's barely worth a mention. The energy is weak (90).

The tail end of the forecast, Tuesday morning, September 8th, shows another calm, glassy morning, but the swell is only 2ft with a 7-second period. The energy is a weak 67. It's a lake. You'd be better off on a longboard or a paddleboard.

So, to wrap it up: Tuesday morning, August 25th, is your best bet. The waves are small but clean and glassy. Wednesday morning, September 2nd, is a second, smaller option. The rest is a long wait of onshore slop. Don't hold your breath for a big swell.

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.
