The Lowdown
Alright, Rusty here, let's talk about what we've got for the Rade de Croisic over the next couple of weeks.
Honestly, mate, it’s a bit of a slow start. The opening days are offering a few waves, but nothing that's going to get your heart really pumping. We've got a lot of marginal conditions and a lot of poor surf windows to wade through before anything decent shows up. There’s a real gap in quality for the first week, with most days being a write-off due to onshore wind or just tiny swell. The combined wave energy is weak, barely getting into triple digits, so don't expect much push. The water temperature is about average for this time of year, nothing unusual there.
The standout window only really opens up on Sunday the 20th of September. The morning session at Rade de Croisic is looking like the best bet for the whole run. We’ve got long-period swell rolling in from the west – 16 seconds, that’s proper groundswell – pushing about 3 ft of surf. The wind will be blowing from the northeast, which is a cross-offshore breeze, keeping things really clean. The combined energy jumps right up to 401, so there’s some proper grunt in the water. For a more exposed break like this, that long period from the west is perfect. Just a heads up that it can get busy here, so expect some company.
The afternoon of that same Sunday is a solid second option. Still plenty of energy (464), a touch more size at about 3 ft, and a 15-second period, but the wind switches to a light cross-on from the north-northwest. It’s still surfable, but the morning window is definitely the cleaner pick.
The following Monday, the 21st of September, is another decent shout for the early. The morning session holds up with clean conditions and a cross-offshore breeze, but the swell energy is starting to fade a bit from the weekend, dropping to 287. It'll be worth a paddle, but don’t expect it to be as punchy as Sunday.
For the rest of the second week, it’s pretty small and underwhelming. After Monday, the swell really drops away. The combined energy falls back to weak two-digit numbers and the wave heights shrink to ankle-busters. You’ll get some clean, offshore mornings, but there just won't be enough swell to ride. If you're desperate for a splash, the 22nd has a clean, offshore morning with about 1 ft, but it's marginal at best.
So to wrap it up: the real highlight is Sunday morning, the 20th of September. If you can, get out there for that. The Monday morning after is okay, but everything else is a waiting game.
Stay frothy,
Rusty
