The Lowdown
Alright folks, Rusty here. Let’s run it down for The Groyne.
Right out of the gate, it’s pretty quiet. Tuesday the 11th gives us waves around 2ft from the east, but a cross-offshore breeze at 12 mph just leaves it messy. By Wednesday morning the 13th, we get glassy conditions on a tiny 2ft easterly, and the wave energy is way down at 85. You’ll be sitting there waiting more than you’re up and riding. It’s a long stretch of nothing much until we get into the second week.
Once the 17th of August rolls in, the swell picks up to 6ft from the southeast, and that sounds good until you see the onshore wind crank up to 22 mph. That combo makes for lumpy, choppy water. The energy is getting up there around 319, but with that wind, it’s not a surfer’s dream. Honestly, with that much wind and that size, you’re better off with a kite than a paddle board.
The real standout comes on the morning of Thursday the 21st. We’ve got a 7ft east-southeast swell with the period stretching out to 10 seconds. The combined energy rockets up to 1425 – that’s some serious power. The wind is still cross-shore at 15 mph, so it’s not perfect, but for an experienced surfer, this is the most interesting window. That size is too much for beginners though.
The outlook fades again after that, with a final clean-ish session on the 25th – 3ft from the east and a cross-offshore breeze at 12 mph. It’s clean, but the energy is only 190. Good for a longboard cruise, but not a heater.
So, if I had to pick just one, it’s that Thursday the 21st morning. It’s got the most push, the biggest waves. The wind is just okay, but you’ll feel the difference. That’s your best shot.
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.
