Floreat groyne Surf Forecast and Surf Report

Alright, let’s break this down. Looking at the 16-day window for Floreat groyne, it’s a real mixed bag. The big highlight is that long-range pulse around Monday the 21st of September, but before that, we’ve got a few fun windows and a couple of dead zones.

Water temp is 63°F – that’s about 3°F colder than the long-term average for this time of year, so you’ll want the 4/3, for sure.

First real look is Tuesday afternoon the 8th. Solid 8ft of WSW groundswell with a 16-second period, and that energy is strong at 3113. The wind is ESE at 15 mph, blowing offshore and keeping it clean. This is proper, heavy surf for the experienced guys – it’s got some punch, and the groyne handles it. Conditions are good.

Wednesday the 9th is a bit smaller, down to 6ft in the morning, but still that nice long-period WSW groundswell with an offshore breeze. The afternoon holds at 6ft, though the energy drops to 1471, but it’s still clean with an easterly offshore. Two solid days.

Thursday the 10th sees it fading. Morning has 5ft and a cross-offshore wind – surfable, but energy down to 920 and the call is marginal. The afternoon is a touch smaller at 4ft with more cross-wind. It’s not bad, but not worth planning around.

The weekend looks messy. Friday the 11th, the swell is down to 4ft but the period is way up at 19 seconds – very long-period stuff that can get weird and straight at a beach/groyne setup like this. We’ve got light cross-shore winds messing with the surface. There’s some energy (1693 in the afternoon), but it’s uncertain. Then Saturday the 12th is a washout with onshore west winds and building swell up to 7ft – just messy, poor conditions. Sunday the 13th is still onshore and lumpy, a no-go.

Monday the 14th is a brief return to form. The morning has 7ft of WSW groundswell with a clean ENE offshore – a proper clean session for those who can handle it. The energy is 1913, but then the afternoon gets a 15 mph cross-shore that chops it all up.

Then another quiet, average spell through Wednesday the 16th. Smaller waves, cross-shore winds, not a lot of push. This is the gap you’d give a miss.

Now, Thursday the 17th and Friday the 18th are grim. Onshore winds, building, choppy, messy – some proper poor conditions. Friday has a strong breeze and rain, so definitely skip that.

Here’s where it gets interesting. Saturday the 19th and Sunday the 20th of September, it’s way too big. We’re looking at 12ft to 13ft of WSW swell, with strong energy readings (3414 and a huge 7494). This is unequivocally too large and powerful for Floreat groyne – this break won’t handle that. It’s a washing machine, not surfable for paddle, and it’s really only for experts at a reef. It’s not. I’d say this setup looks way more interesting for kite surfing than paddle surfing. Give it a miss.

And that brings us to the standout. Monday the 21st of September – this is the one. The swell has backed off slightly to a very solid 10ft, but it’s still a powerful WSW groundswell with a 17 to 18-second period. The energy readings are huge – 6204 in the morning and 5509 in the afternoon. But here’s the kicker: the wind is offshore and light. Morning has a 15 mph ENE offshore, keeping it moderate but clean. The afternoon is the gem – a light ESE offshore at 6 mph, glassy, clean, proper. This is excellent surf for experienced surfers on a big, clean, powerful swell. It’s going to be big, challenging, but perfect. That’s your standout.

After that, Tuesday the 22nd sees it dropping to 8ft, still decent but with a more onshore tendency in the afternoon. The energy is still moderate (2911), but it’s not the same, and by Wednesday the 23rd, it’s fading into the 5-6ft range with cross-onshore winds and poor shape. That’s the tail end.

So, to sum it up: Tuesday the 8th and Wednesday the 9th are your early calls. Monday the 21st is the one to circle on the calendar – it's promising, but being that far out, anything can change. The rest is either too small, too messy, or way too big. You take those windows.
