The Lowdown
G’day, Rusty here, and I’ve gotta be straight with you – the next couple of weeks are looking pretty bleak for a paddle. The groyne's a reef setup that's exposed to the swell, but the conditions just aren't lining up for a proper session for a long stretch.
We start off on Wednesday, 29 July, with a real tease. The water’s sitting at 68°, which is a bit colder than usual for this time of year, but the swell’s tiny at 2ft from the E with a short 6-second period and the combined energy is weak (36). The wind is glassy from the SW, but the waves are just too poor to bother with. The whole first week is a write-off – from 29 July through to the 12th of August, there’s nothing but poor surf conditions and cross-onshore winds mucking things up. The swell gets a bit of a bump on the 2nd of August, with 5ft from the E and energy hitting 304, but the wind is straight onshore from the ESE, so it’s choppy and messy. Not worth suiting up.
The first real glimmer of hope comes on Thursday, 13 August, about two weeks out. The morning shows a clean 4ft swell from the SE with a very long period of 12 seconds – that’s proper groundswell energy. The combined energy is strong (337), and the wind is a light cross-offshore from the NNW, keeping things glassy. This is the standout of the whole outlook. The groyne is a reef, so that long-period SE swell should wrap in nicely and offer some clean, lined-up waves. It’s a bit on the small side, but the quality should be there for intermediate surfers. Just be aware that this break can get crowded at times, so get in early. The afternoon sees the swell push up to 5ft from the SE with an even stronger energy of 609, but the wind swings to a cross-shore from the NNE, which might bring a bit of chop. It’s still the best we’ve got, but it’s more for the experienced crew with that size.
Honestly, if you’re waiting for a wave, the 13th of August is your only real shot. The rest is a long, flat, windy wait. Hang in there, mate.

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.
