The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for The Groyne.
First up, the water is sitting at 68°, which is a touch cooler than what we’d normally expect this time of year, so you might want to dig out the 4/3.
The outlook is a bit of a slow burn, to be honest. We’ve got a whole lot of nothing happening from the start of the period. Monday the 3rd kicks off with just 2ft of swell from the SE, but cross-shore winds and a combined wave energy of only (349) make it feel weak and messy. It’s a no-go.
Tuesday the 4th looks a little more promising. The morning is where it’s at—the wind drops to glassy, dead calm with a light 2ft of SE swell. The period is a solid 9 seconds, and the energy is still modest (105), but that glassy surface will make it look way better than it is. It’s surfable, but very ordinary. Still, if you’re desperate for a paddle, that Tuesday morning glass-off is your best bet in the first week.
Wednesday the 5th morning sees a clean 3ft from the E with a light SSW cross-off breeze. Very clean conditions, but the energy is only moderate (168). Again, nothing to write home about but it’s rideable.
From Thursday the 6th right through to the end of the first week, the wind and swell don’t line up. We get a bit of a bump in size on Saturday the 8th with 5ft in the morning and 5ft in the afternoon, but the wind is cross to cross-on, and the period is a short, weak 7 seconds. The combined energy jumps to (205) and (263) respectively, which is moderate, but it’s just messy and choppy. Not worth the paddle.
The second week starts the same way. Nothing really clicks until we get a stand-out window. Mark your calendar for Saturday the 15th of August. The morning session is the clear winner of the entire 16-day forecast. We’ve got a clean 4ft of SE swell, with a glassy, offshore wind from the W. The water will be like a mirror. The period is 8 seconds, so it’s not groundswell, but with that wind and a combined energy of (249), it’s going to be the best quality wave we see. The Groyne is a reef, so that SE swell direction is right on the money for what it likes. Keep in mind, crowds are ‘sometimes’ here, so if it’s clean and glassy, expect a few others who’ve been waiting for the same window.
The rest of the weekend and into Monday the 17th and Tuesday the 18th sees the wind pick up strong again, with onshore cross-chop ruining the 3ft to 4ft of swell. The energy is there (like 252 on Tuesday), but you’ll be fighting the wind.
So, Rusty’s bottom line: The first week and a half is a write-off for anything decent. The only real standout is Saturday the 15th of August morning. Set your alarm, because that’s the one.
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.
