The Lowdown
Alright, Rusty here again. Let's break down the same outlook but in the old-school units.
So, for the Rade de Croisic zone, it's looking like a long dry spell. The first week or so is pretty much a bust for any decent surf.
We start on Friday, August 21st, with a small, onshore 3-foot swell from the W, but that 18 mph wind is ruining it. No good. That pattern holds for the next week and a half. We get a few tiny pulses of swell, but they're all buried under poor conditions – strong winds from the wrong direction, or just flat spells. There's a little glimmer on Saturday the 22nd with a 2-foot swell and cleaner cross-off winds, but it's just too small to get excited about. The whole run from the 21st right through to the 30th of August is a total dead zone for worthwhile waves. Lots of fresh offshore wind days, but nothing to ride.
Then, finally, a bit of hope. The morning of Monday, August 31st, is where it gets interesting. The swell comes up to 4 feet from the WSW, and we've got light cross-offshore breezes from the SSE making for clean conditions. The combined energy is moderate, a real step up from the flatness before. This is your best bet in the whole run, but it's still not a classic, and it's only one session.
Then it's back to mush for a few days until Thursday, September 3rd. The afternoon brings a solid 8-foot WSW swell, but it's cross-onshore and lumpy. That's gonna be a messy, blown-out mess. Not for paddling.
The real standout, and I mean the *only* real standout, is the morning of Friday, September 4th. We get a clean 4-foot WSW swell with glassy conditions. The combined energy is solid, and with the wind dead flat, it'll be as clean as it gets. That's the one session to circle on the calendar. The swell period is short at 8 seconds, so it won't have much power, but for the area, that's as good as it's going to get.
So, to wrap it up: don't bother for the first ten days. Mark your calendar for the morning of Friday, September 4th. That's the only window where the stars align for a clean, rideable wave. The rest is just waiting for the next system.
Rusty.
