The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s coming up for The Groyne.
Truth be told, the next 16 days are a tough watch for any surfer chasing quality. The swell stays small, and the winds are rarely kind. There’s no standout session that really jumps off the page, but if you’re desperate, there are a few windows of cleaner, glassy conditions with just enough bump to paddle out. The combined swell energy is mostly weak to moderate, sitting between 86 and 346 throughout the period, so don’t expect any grunt.
We start with Saturday morning, 22 August. A 3ft easterly swell at 7 seconds – that’s short-period wind slop – with a light cross-off breeze. It’s surfable but very ordinary. Combined energy is only 86, so it’s weak. By afternoon, the wind picks up to 9 mph and conditions drop right off. Sunday and Monday stay small, 3ft to 3ft, on cross or cross-onshore breezes that mess up the surface.
Tuesday morning 25 August is the first time we get a real chance. The swell is 3ft from the east-northeast, still short at 8 seconds, but the wind goes glassy. Combined energy bumps to 143. It’s only ordinary, but those glassy conditions mean the lines will be the cleanest we’ll see, even if the waves are small. Crowds are possible here sometimes, but on a Tuesday with conditions like this, it shouldn’t be too bad.
There’s a long gap after that. From Wednesday 26 August into the weekend, winds go cross-shore or cross-onshore, the swell hovers around 3ft–3ft, and energy builds a little but the surface stays choppy. By Sunday 30 August, a bump in swell to 5ft – 5ft and stronger southerly winds kick up a lumpy, messy ocean. That kind of setup is more interesting for kite surfing than paddle surfing.
Monday 31 August stays ugly, then we get another clean window on Tuesday morning, 1 September. A 3ft easterly swell at 8 seconds with glassy wind again – combined energy 146. That’s your second best option, but again, very ordinary quality. Wednesday morning 2 September and Friday morning 4 September also offer glassy starts with 3ft–3ft swell and longer periods at 10 seconds, energy around 122–193, but still those are just small, clean, mundane waves.
From Saturday 5 September right through to the end of the outlook on Sunday 6 September, the swell drops to just 2ft, winds get fresh and lumpy, and energy weakens below 100. That’s a flat, blown-out finish.
So, the only real standouts – and I’m using that term loosely – are Tuesday morning 25 August and Tuesday morning 1 September. Both offer small but glassy surf. If you need a fix, those are your windows. Otherwise, it’s a long, ordinary run of small, messy conditions. Forecasts change, though, so don’t write it off completely.
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.
