The Lowdown
G’day, Rusty here. Righto, we’ve got one spot on the radar for this 16-day run – Floreat groyne – and it’s a bit of a mixed bag, with plenty of size but also plenty of wind to work around. The water’s sitting at 63°, nearly 3° cooler than average for this time of year, so it’s a bit colder than normal – you’ll want a decent wetsuit.
The whole period kicks off with solid WSW swell, but the conditions are all over the shop. The standout window is Thursday morning, 20 August – that’s the pick. You’ve got 8ft of WSW groundswell, pumping with a very long 16-second period and a massive 3351 units of wave energy, and it’s dead glassy with light SE wind. That’s about as clean as it gets for a spot this size, but at 8ft, it’s well into expert territory – this is not for beginners.
Friday morning, 21 August, still looks tidy with 7ft WSW swell, 15-second period, and light offshore easterly wind, keeping things clean. That’s still a solid, powerful wave and a good backup session if you miss Thursday.
The following Monday morning, 24 August, brings another chance with 6ft WSW swell and light offshore easterly again – clean and fun, though the energy has dropped to 1396 units. Still a decent paddle for experienced crew.
Things get a bit messy from the 25th through the 29th – the swell drops, and cross-shore winds ruin most of the quality. Then on Wednesday morning, 26 August, a massive pulse arrives: 10ft WSW swell with an 18-second period and 5151 units of energy – huge numbers – but it’s cross-onshore from the WNW and choppy, so the quality is cooked. That’s more of a kite-surfing setup than a paddle day, to be honest.
Moving into the second week, there’s a promising morning on Monday, 31 August: 7ft WSW swell, 16-second period, and light cross-offshore NNE wind, making for clean waves. That’s a solid option and worth marking in the calendar. Wednesday morning, 2 September, also looks good with 7ft WSW swell and clean offshore easterly wind.
Overall, the real standouts are Thursday morning 20 August and Monday morning 31 August – both offer decent to solid size, clean conditions, and the long-period groundswell shaping up nicely for a groyne setup like this. Just remember, there’ll be long lulls between sets with that long period, so paddle out when you see a gap. Crowds are sometimes an issue here, so pick your time. This is Rusty, signing off.

Information about the Floreat groyne Surf forecast
The above surf forecast table for Floreat groyne provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Floreat groyne can be found by selecting the local surf guide option on the grey menu.

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 Floreat 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.
