The Lowdown
G’day, I’m Rusty. Let’s see what’s cooking at The Groyne over the next couple of weeks.
To be honest, it’s a slow start. The first week and a half is mostly tiny, choppy, and not worth getting wet for. The water temp is sitting at 68°, which is a bit colder than usual for this time of year – so grab a thicker suit if you’re thinking of going in.
Things finally turn around on Thursday 13th August. That’s when we get a decent pulse of groundswell from the ESE, around 4ft with a 12-second period. Combined swell energy hits 429 – moderate energy, so there’s some grunt. The wind goes offshore out of the WNW, light and clean, and stays offshore through the afternoon from the WSW. That’s your standout window. The Groyne is a reef break, exposed to that SE swell, and with offshore winds it’ll be clean and well-shaped. Not too big for intermediates, but it’ll be fun.
Friday 14th August morning still has some clean leftover swell – 3ft, 12-second period from the east, with a light cross-offshore breeze. Combined energy is 379, still moderate. Solid option if you missed Thursday.
After that, it fades back into small, messy surf. Your best bet is that Thursday 13th and Friday 14th window – don’t sleep on it.
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.
