The Lowdown
G’day, Rusty here. Let’s have a look at what’s on the menu for our stretch of coast over the next couple of weeks. The gist of it is: we’ve got a solid run of groundswell on the way, but the wind is going to be the main character in this story. Don’t get too excited about the first few days, because while there’s size, it’s going to be lumpy and crossed-up. We’ve got a couple of standout windows where everything lines up, though, so let’s break it down.
First off, the main break we’re working with is Floreat groyne, a beach/groyne setup that handles the west-southwest swell pretty well. The water temp is about average for this time of year, so nothing wild there.
The window kicks off on Saturday the 22nd. Early morning has some clean potential with a 6.2ft WSW groundswell, period of 16 seconds, and that super long period is a real energy bomb. The wind is light from the NE, almost glassy, and the wave energy is strong at 1881. That’s the first highlight – for experienced surfers, this is going to be firing. It’s a touch overhead, but with that long period and clean surface, the groyne should be handling it well. The crowd factor is a “sometimes” deal, so you might have some company, but it’s worth it.
The rest of that weekend, though, is a write-off. Saturday afternoon the wind swings to a fresh 30 km/h southerly, cross-shore, and it just gets messy. Same story for Sunday – the swell drops a bit, but the wind stays cross and the surface gets chopped. You’re better off doing something else.
Monday the 24th morning is another standout. Swell bumps back up to 6.9ft from the WSW, period 14 seconds, and the wind is a glassy 5 km/h from the SSW. The wave energy is strong at 1680. Again, this is “excellent surf conditions for experienced surfers.” Clean, solid, and holding. That’s your best bet in the first week. Monday afternoon goes cross-on with a light breeze, so grab it early.
Tuesday the 25th is a mess – moderate cross-onshore winds and choppy conditions. The size is there, but the quality is not.
Now, here’s the big one. Wednesday the 26th. The swell jumps to a serious 11.5ft from the WSW, with a period of 19 seconds. That’s not just a groundswell, that’s a beast. The energy reading is off the charts at 17734. But the wind is a fresh 30 km/h cross-onshore and it’s lumpy as hell. This is way over 8ft, so it’s experts-only territory, and with that wind, it’s going to be a battle. Honestly, for a beach/groyne setup with this much size and onshore wind, this looks more interesting for the kite crew than for paddle surfing. Stay out of the water unless you’re a masochist.
Thursday the 27th is still big – 7.9ft to 8.2ft – but the wind is cross-shore and stronger in the afternoon, so it stays marginal. Not clean.
Then we get the real gem. Friday the 28th morning. The swell drops back to a manageable 5.6ft from the WSW, period 13 seconds, but the wind goes offshore from the ENE at 20 km/h. That’s the classic combo. Clean, walled-up, and the groyne will be holding its shape. The energy is moderate at 908, but the quality is what we’re after. This is a great surf day. Light offshore and clean. This, along with Monday the 24th, is the best on offer.
The rest of that weekend and into next week is a mixed bag. Saturday the 29th drops right off – small and weak, not worth your time. Sunday the 30th picks back up to 5.6ft with a longer period, but the winds are cross-offshore or light cross-on, so it’s just okay. Nothing special.
Monday the 31st morning is promising – 4.6ft but with an 18-second period, which is a really long interval, and a light cross-offshore breeze. Clean conditions and good energy for the size. That could be fun on the point.
After that, we’re looking at a run of days where the swell stays in the 6.2ft to 7.5ft range, but the wind keeps flipping between cross, cross-on, and light and variable. The standouts are few and far between. Thursday the 3rd of September morning looks interesting – 6.2ft, 13 seconds, and the wind is calm, glassy. That’s a solid window for a clean session. But as we get further out, the reliability drops. Friday the 4th is poor, and the following weekend is all cross-onshore and choppy again.
So, to sum it up: don’t bother with this weekend’s afternoons. Your two real standouts are Monday morning, August 24th, and Friday morning, August 28th – both have solid groundswell, clean winds, and that groyne will be working. The big Wednesday swell is

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.
