The Lowdown
Alright, this is Rusty, and I’ve got the lowdown for Floreat groyne. It’s a bit of a mixed bag ahead, but there are a couple of windows where things line up.
Right off the bat, we’ve got a big, messy pulse of swell moving in on Monday the 17th. The combined energy is massive (1831) with a 6ft swell from the WSW, but a howling 25 mph NW wind is just going to tear it apart. It’s cross-on and messy, so don’t bother paddling out. Monday afternoon gets even worse: a 13ft monster with a 28 mph onshore wind. That’s serious power (3850), but it’s unsurfable.
Tuesday the 18th sees the swell staying huge at 12ft, and the wind is lighter, but it’s still onshore or cross-on. The energy is pumping (6079), but it’s simply too big for this break. The water temperature is 62°, which is 4° colder than normal for this time of year, so you’ll feel that chill.
Wednesday the 19th is a write-off with marginal conditions and questionable tides. The swell drops a little, but the wind is junk.
Now, here’s where it gets interesting. Thursday morning, the 20th. The wind goes glassy, with an 8ft WSW swell and a period of 16 seconds. That’s a long-period groundswell with real energy (3351). The report says excellent conditions for experienced surfers, and that’s your best bet. This is a beach/groyne setup, and with that long period, it might wall up a bit straight, but in the glassy morning, it’ll be clean. Keep an eye out for crowds, as it’s a spot that’s sometimes busy.
Friday morning the 21st is another beauty. Glassy conditions again, with a 7ft swell from the WSW. The energy is still solid (1847), and that offshore ESE breeze will keep it clean. This is your second standout. The water is still cold, but the waves will be worth it.
Saturday the 22nd has a clean, cross-offshore morning with a 6ft swell, but the energy is dropping. It’s a fun size, but not the peak of the run.
From Sunday the 23rd onward, things get ugly again. Onshore winds and poor surf conditions dominate, with a big swell on Sunday afternoon (8ft, 4452) being blown out. The following week is a frustrating run of onshore wind and poor surf, with the odd marginal window. The best of the rest is Friday the 28th afternoon, when the wind goes glassy again with a 6ft swell, but the energy is moderate (1551). It’s not the same quality as the 20th and 21st.
So, bottom line: don’t waste your time on the first few days. Set your alarm for Thursday the 20th or Friday the 21st. Those two mornings are your true standouts. Everything else is a battle or a wait.
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.
