The Lowdown
Alright, Rusty here. Let's talk about what Floreat groyne is looking like for the next couple of weeks.
The first real chance to get wet is on Friday, August 21st. We've got a solid groundswell coming in at 7 to 7 feet from the WSW with a long 15-second period. The combined energy of all that is a punchy 2032, so you'll feel it push through. Morning is the call here, with a light offshore breeze from the east keeping things clean. This isn't a beginner wave; at this size and with that long period, it's for the crew who can handle a bit of juice. By the afternoon, the wind goes cross, and the waves get a bit messy.
Saturday the 22nd drops to about 6 feet but with an even longer 16-second period. The morning wind is light, so it might have a glassy window, but expect the usual crowd.
The clear standout of the first week is Monday, August 24th. Another pulse of 7 to 7 foot WSW groundswell with a 14-second period and a combined energy of 1772. But the winning ticket is the wind: a light cross-offshore breeze from the north-east that will have these waves groomed and peeling. This is the one for anyone comfortable in overhead surf. Water temp is about normal for this time of year, so a 3/2mm wetsuit is what you want.
Things go totally off the rails from the 26th. We get a massive 11 to 12 foot pulse of WSW swell, but it's accompanied by strong onshore winds, making it a total washout. The energy is a crazy 8124, but it's just too big and blown out for this spot. The following days are full of howling onshore winds and poor quality waves.
Looking further out, the light at the end of the tunnel is Saturday, September 5th. Right now, it looks like a beauty: a clean 7 to 7 foot WSW swell with a 14-second period. The combined energy is a meaty 3194, and the forecast is for glassy conditions with a light east breeze. That's a rare combo for Floreat. It's a long way off, so don't get your heart set just yet, but if it comes together, that is your session of the forecast period.
So, for the experienced surfer, mark Monday, August 24th, and keep a very close eye on Saturday, September 5th.
Rusty.
