The Lowdown
G’day, Rusty here. Let’s talk about The Groyne for the next couple of weeks. It’s a reef break that’s fairly consistent, but the conditions are going to be a mixed bag. The water temp’s about normal for this time of year, so nothing unusual there.
The first real chance to get wet is Wednesday morning, August 5th. We’ve got a 3ft swell from the east, with a 10-second period – that’s a proper groundswell with some grunt. The combined energy is moderate (204), and the wind is glassy, calm out of the southwest. That’s as clean as it gets. The Groyne is a reef, so it’ll handle that long-period swell, and the swell direction matches the optimum (SE), so it’ll be lined up nicely. It’s a small wave, good for intermediates, but it might get a few people out there – it’s known to be crowded sometimes. The afternoon turns to crud with a 10 km/h onshore wind from the ENE.
Monday morning, August 10th, brings a 3ft swell from the east, 9-second period, with moderate energy (147). We’ve got a light cross-offshore breeze from the southwest, keeping it clean. It’s a small, surfable wave, nothing special, but a solid session.
Wednesday morning, August 12th, is more of the same: 2ft from the east, 9-second period, clean cross-offshore wind from the SSW. Energy is low (88). A small, tidy wave, but don’t expect much push.
Saturday morning, August 15th, is a mess with 20 km/h cross-shore winds and a 2ft swell. Skip it.
Sunday morning, August 16th, we get a glassy morning again. 3ft from the east, 10-second period, with a light southeast breeze. Energy is moderate (137). It’s a “surfable” morning, but it’s ordinary. Still, a glassy reef with a bit of groundswell is worth a look.
Monday morning, August 17th, is also glassy, dead calm from the east, with 2ft, 10-second period. Energy is moderate (127). Another small, clean session.
The standout is Wednesday the 5th. That glassy morning with the 3ft east swell and 10-second period is going to be the best of the bunch. The reef handles the long period, and the direction is perfect. Get out there early before the wind shifts. The 16th and 17th are okay for a paddle, but the 5th is the one to circle on the calendar.
Stay stoked, 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.
