The Lowdown
Alright, this is Rusty, and I’m looking straight at our local setup. I won’t sugarcoat it – it’s a bit of a mixed bag, but there are some windows if you play your cards right.
The main event, and really the only show in town for the next week, is Floreat groyne. We’ve got a solid, long-period WSW groundswell pushing through, and the combined wave energy is in the strong to very strong range (2174) for the start of the period. That’s a lot of grunt in the water. Water temp is sitting at about 64°F, which is about 2°F cooler than average for this time of year, so nothing too wild, just a touch of autumn chill hanging around.
Sunday the 13th is a write-off. The wind is onshore from the west at 9 mph, making a mess of that 7 ft swell. It’s lumpy and ugly – a classic “look but don’t paddle” day.
Now, Monday the 14th is where it gets interesting. The morning is the standout of the whole outlook. We’ve got a clean 7 ft swell from the WSW with a 14-second period, but the magic is the offshore easterly breeze at just 6 mph. That’s going to groom that groyne into something special. It’s a beginner-friendly spot, but at this size (over 5 ft), it’s pushing into intermediate territory – the entry-level crew should sit this one out. The energy is still massive, sitting around 1969, so you’ll feel the power. Monday afternoon gets messy again as the wind swings cross-shore, so make it a dawn patrol mission.
Tuesday the 15th keeps the goods rolling. Morning has a stronger offshore easterly at 16 mph, and the swell is still a solid 7 ft. It’s a bit more powerful and hollow with that push, still clean. The afternoon eases slightly to 6 ft with a lighter offshore, and it’s surfable but the morning window has better shape. Energy is still high (1578 in the morning).
After Tuesday, things go downhill fast. Wednesday the 16th morning is marginal with a drop to 4 ft, and by Thursday the 17th, the onshore northwesterlies kick in and don’t let up for days. From Thursday the 17th all the way through to Monday the 21st, it’s mostly cross-onshore junk at around 4 ft to 4 ft. The groyne is just not set up for it. That stretch is about 4-5 days of proper slop, not worth paddling out for.
There’s a glimmer on Sunday the 20th afternoon. A very light SSE breeze at 3 mph and a clean 6 ft swell – that’s a pretty little window, but the energy has dropped to a moderate 787. It’s a fun, easy session, not a standout.
The next real chance is Wednesday the 23rd morning. The swell is back to 6 ft from the WSW, the period is a juicy 15 seconds, and we have a light offshore from the ESE at 6 mph. It’s clean with good energy (1284) – this is a solid day for anyone who can paddle. After that, the onshore winds return and the swell fades into the late September, closing out the 16-day run with small, windy conditions.
To sum up: Monday the 14th morning is your absolute best bet – big, clean, powerful groundswell with perfect offshore wind. Tuesday the 15th morning is a close second. Everything else is either too windy or too small to get excited about. A couple of mellow afternoons (like Sunday the 20th) are worth a paddle if you’re desperate.
Rusty.

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. Our Floreat 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 (Floreat 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 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.
