The Lowdown
Alright, Rusty here. Let's have a good hard look at what's coming our way for the next couple of weeks at Floreat groyne.
We've got a bit of a mixed bag, but there are definitely a couple of windows to get excited about later on. The setup here is a beach and groyne, so it can work well with the right direction. The water temp is about average for this time of year, nothing wild there.
This Thursday the 10th of September is just a tease. The morning has a clean 5ft swell from the WSW with a very long 15 second period, but that ENE wind is howling at 16 mph making it a bit ugly. The afternoon cleans up nicely with a pure offshore breeze, dropping to 4ft, but the combined energy is only moderate (806). It's a bit of a heartbeat starter but not the main event.
Friday the 11th is a bit of a letdown. The morning has that same 4ft WSW swell, but the wind is cross-off and the swell period drops a second. The afternoon gets even worse, with a 4ft, 19-second groundswell but a cross-on wind that'll chop it all up. The combined energy is moderate (1566), but the quality just isn't there.
The whole weekend is a write-off. Saturday the 12th and Sunday the 13th are all onshore winds and poor conditions. Swells are from 4ft to 7ft but the wind is just wrecking it. You'd be a glutton for punishment to paddle out.
Now, here's where it gets interesting. Monday the 14th of September morning looks like a proper reward for waiting. We've got a clean 7ft swell from the WSW, a 14-second period, and a light offshore breeze from the ENE. The combined energy is strong (1831), and everything is pointing to clean, powerful waves. This is for experienced surfers only though – that 7ft is a solid step up, and the crowd is possible here.
Tuesday the 15th of September morning keeps the run going. Another morning with a 7ft swell from the WSW, a 14-second period, and a light offshore breeze. The combined energy is strong (1887) again. It's another day for experienced crew, but it's a cracker. Afternoon turns to rain showers and a cross-shore wind, so get on it early.
After that, we hit a dry spell. From Wednesday the 16th right through to the 23rd of September, it’s a series of marginal to poor days with onshore and cross-onshore winds. Swells will be around, but the quality will be missing. There's a few days there with nothing to recommend.
Then, look at this – Thursday the 24th of September has a clean 4ft swell with a light cross-off breeze. Not massive, but clean for the morning, and the combined energy is weak (533).
But the absolute standout that you need to write in your diary is Friday the 25th of September morning. The wind is forecast to be glassy – absolutely dead calm – with a 5ft swell from the WSW, and a very long 19-second period. The combined energy is strong (2038). This is a point-break style groundswell, and at a beach and groyne setup that long period might make it a bit straight, but that glassy surface will make any wave you get absolutely perfect. This is the one to circle for experienced surfers. It's a long way out, so forecasts can shuffle, but as a target, it's a beauty.
So, to sum it up: the next few days are for waiting. Monday and Tuesday mornings the 14th and 15th are your first solid windows for experienced surfers. Then there is a big gap of poor conditions until a possible standout on Friday the 25th with glassy conditions and a long period swell.
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.
