The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for The Groyne over the next couple of weeks. I’ll be straight with you – it’s a pretty grim run for the most part, but there are a couple of flickers of hope if you’re patient.
Right now, we’re coming out of a long flat spell. The first chance of anything even close to a wave is on Sunday, 30 August, but honestly, don’t bother. We’ve got onshore winds, a weak 5 ft swell from the SE at a short 6 seconds, and the combined wave energy is only 178 (moderate). It’s messy, choppy, and the surf is poor. This continues right through Monday and Tuesday – small, wind-affected, and ordinary.
The first real window appears on the morning of Wednesday, 2nd September. The swell drops right off to just 2 ft from the east at 10 seconds, which is a decent period for its size. The wind swings light NNW, so it’s cross-offshore and clean. The wave energy is weak at 60, but the conditions will look clean. This is more of a longboard or a fun day for a beginner – it’s not going to get your heart racing, but it’s the first clean surf we’ve seen.
Thursday morning, 3rd September, is similar – 2 ft from the NE at 8 seconds, clean with light NNW winds. Again, small and weak energy (55), but it’s rideable.
Then we hit another dry spell. Friday through to the following Wednesday (4th to 10th September) is mostly tiny – lots of 1 ft to 1 ft days with poor conditions. The morning of Friday, 4th September, is glassy calm but the swell is only 1 ft – barely a ripple.
The standout for the whole outlook is the morning of Monday, 7th September, but with a big “but”. The swell jumps to 5 ft from the NNE at 6 seconds, with combined energy of 172 (moderate). The issue is the wind: moderate cross-shore from the NNE at 16 mph, so it will be choppy and lumpy. That said, 5 ft is the biggest paddleable size in the window, and with the groundswell period being short, it won’t be too powerful. Still, it’s a messy day – not a classic.
Tuesday, 8th September morning, is a different story. The swell holds at 4 ft from the NNE (6 seconds), but the wind swings to a clean offshore from the west at 12 mph. That’s moderate offshore and clean conditions, with moderate wave energy (124). This is easily the pick of the fortnight. The Groyne is a reef setup, and a clean offshore with a 4 ft swell will produce clean, rippable waves. Crowds are sometimes an issue here, but for this one morning, it’s worth the effort.
After that, it’s back to small stuff and poor wind through to the 14th. A final mention for Saturday, 12th September morning – a 4 ft SSE groundswell at 10 seconds, with combined energy of 362 (strong). But it’s raining, and the wind is cross-shore from the SSE at 16 mph, creating a cross-chop. Might look bigger, but it’s not going to be clean.
Best Bet: Tuesday, 8th September morning. Offshore wind, clean conditions, and a solid 4 ft swell with decent short-period punch. It’s your window for a proper surf at The Groyne. Everything else is either too small or too messy.
Keep an eye on the long-range stuff for the 12th – strong energy but messy for now.
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.
