The Lowdown

Alright, grab a coffee and settle in, mate. Rusty here. I gotta be straight with you – this stretch coming up is a tough one. We’ve got a solid 16-day window, but the surf outlook for The Groyne is pretty grim. It’s a reef break, and it’s exposed to the swell, but the conditions just aren’t lining up for a decent paddle. This is a classic case of a blank run for the area; it’s not uncommon to see stretches like this, so don’t let it get you down. Forecasts can change.

The combined swell energy is weak for the entire first week, with values mostly under 100. For example, Friday the 4th shows only 31, and it doesn’t get much better. The swell is tiny, mostly around 1ft to 2ft, and comes from the east with a short period of 9 seconds or less. That’s not enough to push any real power through. The wind is a major problem, too. It’s mostly cross-on or cross-shore, which keeps the surface choppy.

There is a slight tease on the 6th, Sunday morning, with a clean cross-offshore wind from the NNW, but the swell is only 2ft from the NNE with a period of 5 seconds. The swell height is just too small and the period too short – it’s barely a ripple. The energy is still weak at 47.

The real action, if you can call it that, comes on Thursday the 10th. The afternoon brings a jump in swell height to 8ft from the SE, with a period of 7 seconds and a combined energy of 598 (moderate wave energy). That’s the biggest swell of the forecast. But – and it’s a big but – the wind is screaming from the SSE at 22 mph, creating a lumpy cross-chop. The summary says “poor surf conditions” and the score is a zero. With that strong wind and the size, this beach setup looks more interesting for kite surfing than paddle surfing. It’s a mess.

The tail end of the forecast, around the 18th and 19th, shows offshore winds swinging in from the WNW and WSW, gusting up to 19 mph. The swell is tiny, though, 0.7ft to 3ft, with weak energy. It’ll be clean, but there’s no wave to ride. On the 17th, there’s a brief moment of light offshore wind, but again, the swell is only 1ft to 2ft. It’s clean but not surfable.

Overall, there are no standouts here. The best of a bad lot is probably the early morning of the 14th of September, with glassy conditions and a tiny 2ft swell from the NE. It’s a long shot, but you might find a little knee-high ripple. Don’t expect anything else. For the rest of it, save your energy.

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.
