The Lowdown
G’day, it’s Rusty. Let’s talk about the Rade de Croisic stretch over the next couple of weeks. Honestly, it’s a tough run for anyone chasing a decent wave. The first week or so is mostly a write-off – windy, messy, and the swell just isn’t working with the conditions. There are a few small windows where it might be worth having a look, but nothing to get excited about.
We kick off Wednesday morning with small 1ft SW swell but the wind is cross-off, so it’s clean. The energy is weak (17), and with a 5-second period it’s just not doing anything. Afternoon gets a little more size, 2ft, still clean with offshore wind but again, period is tiny and the combined energy is only 30 – it’s poor surf. Thursday and Friday see the swell bump up a bit, but the wind swings cross-onshore and the water gets choppy, with combined energy climbing but the quality dropping fast. Friday afternoon hits 7ft from the WSW, but with a strong cross-onshore breeze at 25 mph and a 9-second period, it’s a messy, blown-out mess (energy 673).
The weekend stays grim. Saturday has 6ft to 7ft WSW swell but cross-onshore winds and lumpy conditions. Sunday morning shows a tiny glimmer – 4ft from the WSW, cross-shore wind, light breeze, and combined energy of 308. It’s still a marginal call, and the period is 9 seconds, but if you’re desperate, it might be the least bad of the bunch. It’s still not good, though.
Monday and Tuesday next week stay poor, with cross-onshore to onshore wind and surf quality that’s just not worth paddling out for. The first real chance of something surfable comes on Thursday morning, 3rd September. The swell drops to 2ft from the west, but we get a clean window with cross-offshore wind from the SE and only a slight air. It’s small, but clean – combined energy is 61, and the period is 9 seconds. It’s ordinary, but you could get a few if you’re on a log.
Friday morning, 4th September, is the standout. The swell lifts to 3ft from the west, with glassy conditions – wind is light, near nothing, and the period jumps to 12 seconds. The energy reads 176, which is solid for the size, and that long period means proper groundswell. This is your best shot in the whole outlook: clean, lined-up waves at Rade de Croisic that will hold together well, especially if the swell direction matches the optimum SW direction. Crowds are sometimes an issue here, so keep that in mind. The water temp is about average for this time of year – nothing unusual.
After that, it fades again over the weekend and into the second week. There’s a small spike on Tuesday morning, 8th September, with 5ft from the west and a 10-second period, but the wind is cross-onshore and it’s only marginal (energy 650). Wednesday morning, 9th September, has a 7ft west swell with a 9-second period, a light cross-shore wind, and energy of 685 – it’s a bigger swell but the period is short, so it’s more of a lumpy, fat wave. For experienced surfers only at that size.
The very last entry, Thursday morning, 10th September, shows 7ft WSW swell, glassy conditions, but the period is only 6 seconds – that’s a short, weak swell with combined energy of 291. It’ll be clean on the eyes but the waves will be crumbly and gutless.
Overall, the only real standout is Friday morning, 4th September. Small but glassy, long-period west swell at 3ft – that’s your window. For the rest, it’s a long wait with a lot of messy, onshore junk. It doesn’t tend to stay poor forever around here, but this stretch is a real test of patience.
Rusty.
