The Lowdown
Alright folks, Rusty here. We’ve got a solid 16-day window on the table for Floreat groyne, but it’s a bit of a mixed bag. The water is sitting at 63°, which is a touch colder than usual for this time of year – nothing crazy, just a bit of a chill in the air.
The first few days are a write-off, to be honest. We’re looking at a messy start with strong cross-onshore winds and poor surf conditions through Monday and into Tuesday. The wave energy is pumping strong (2420), but it’s all over the shop. Not worth paddling out for.
Things start to turn around on Thursday morning, August 13th. The wind goes glassy, the swell settles to 6 ft from the WSW, and the energy is still healthy (1650). That’s a real standout window – clean, glassy conditions for experienced surfers. The break can get a bit inconsistent, but when it’s like this, it’s worth the wait. Crowds can show up sometimes, so get in early.
Friday morning, August 14th is another beauty. Clean, cross-off wind, 7 ft WSW swell with a long 16-second period, and solid energy (1904). This is a classic groundswell setup – the waves will have shape and power, but the long period means the sets will be spaced out. Paddling out will be easier because of the gaps. Friday afternoon holds up nicely too.
Saturday morning, August 15th is a bit more marginal with a moderate breeze, but the afternoon glass-off is a real treat. 6 ft swell, glassy, and decent energy (1318). For a beginner spot, this is as good as it gets.
Now, into the second week, we hit a rough patch. Monday, August 17th sees strong cross-onshore winds and messy surf. Then Tuesday, August 18th is a tricky one – the swell jumps to 12 ft with huge energy (4546) and light offshore wind, but it’s just too big for this break. Only for experts, and even then, it’s a big call.
The real standout of the whole run might be Saturday morning, August 22nd. 8 ft of WSW swell, a long 18-second period, clean cross-off wind, and massive energy (5044). The swell direction is dead on the optimum for this spot. This is a serious session for experienced surfers. The sets will be long and powerful, so don’t paddle out unless you’re on your game. Crowds are likely on a day like this.
Sunday morning, August 23rd is also a solid option – 7 ft, clean, with good energy (1776). A nice way to round out the run.
The last few days of the window (August 24th and 25th) get messy again with strong onshore winds and lumpy surf. Not worth the drive.
So, to sum it up: the best bets are Thursday morning, August 13th for the glassy conditions, and Saturday morning, August 22nd for the big, clean, powerful swell. Mark your calendar.
Rusty.
