The Lowdown
Alright, mate, Rusty here. Let’s break down what’s cookin’ for the next couple of weeks. Gotta be honest, this one’s a grind. The whole 16-day window is a struggle, with most sessions rated as poor. The first real chance to paddle out doesn’t show up until the very end, so brace yourself for a long dry spell.
The first hint of anything worthwhile comes late on Wednesday, September 2nd. For the Rade de Croisic area, Wednesday morning shows a "marginal" call. We’ve got a light cross-shore breeze, a 5ft swell from the W, with a period of 9 seconds. The combined energy is moderate (326). The water temp is about 69° with a +1.0° anomaly, so it’s a touch warmer than average for this time of year. That’s a small positive, but the surf quality is still iffy. If you’re itching to get wet, this is the closest thing to a go, but keep your hopes in check.
The rest of the period is a total bust. From now through early September, you’ll see nothing but poor surf conditions with onshore winds, lumpy seas, and tiny swell. There’s a big gap of no real surf action until that September 2nd window. Honestly, it’s a rare blank run for this area, so don’t get too down – forecasts can flip, and it usually doesn’t stay this quiet for long.
After that, late on Thursday, September 3rd, we get a 6ft swell from the WSW with a period of 8 seconds, but it’s cross-shore and the combined energy is moderate (408). Still, it’s a messy setup with a cross-chop, so it’s not the clean stuff we’re after.
The standout? There isn’t one. The best you can hope for is that Wednesday morning session on the 2nd. It’s the only time the wind behaves, and the swell is rideable, but it’s marginal at best. For now, I’d say keep your board waxed and your eyes on the forecast – sometimes the ocean surprises you.
Rusty.
