The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Honestly, it’s a tough stretch. We’re looking at a long run of pretty average conditions. The Groyne has small swell on offer most days, but the wind and the wave quality just aren't lining up. The water is sitting at about 68°, which is a bit colder than usual for this time of year – you’ll want a decent suit.
The first glimmer of something we can work with is way down the track, on the morning of Friday, September 5th. The wind goes glassy from the NNE, the sea is calm, and we’ve got small 3ft swell from the ENE at 8 seconds. The combined energy is weak (102). It’s not going to blow your mind, but if you want a clean, small-wave session without crowds, this could be your window.
The only other morning that looks even slightly worthwhile is Saturday morning, August 30th. We get a 5ft swell from the ESE, but it’s a short period windswell at 6 seconds, with a moderate SSW cross-off wind. The combined energy is moderate (225). The wind keeps it clean, but the quality is only just on the edge of being surfable. Beginners might find the 5ft a bit of a handful.
Realistically, there’s no standout, firing day here. The rest of the period is plagued by cross-onshore winds and choppy, poor conditions. It’s one of those quiet runs where you just have to wait for the forecasts to change.
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.
