The Lowdown
Alright, Rusty here, looking at the waves for Rade de Croisic. Gotta be straight with you, it's been a tough stretch and honestly, it doesn't look like it's letting up much over the next 16 days. We're looking at a long, frustrating gap to start with a whole lot of nothing good on the menu. The water is sitting at 69°, which is a touch warmer than normal for this time of year, but that's about the only upside.
The forecast is a real heartbreaker. From now through the end of the period, it’s almost all “poor surf conditions” with onshore and cross-onshore winds. The swell energy is weak, mostly sitting in the double digits (30 – 114) and rarely hitting even moderate levels. We do get a blip of moderate energy on the 7th (301) and 9th (348), but the wind is straight on it, ruining any chance of shape. On Monday the 8th, the wind is howling at 25-28 mph from the SW and NNW, making it a total mess and more suited for a kite than a paddle.
There are two brief windows of glassy conditions, but the swell is pathetic. On Thursday morning, the 10th of September, we get a glassy sea state with 2 ft of swell out of the W at 8 seconds. The combined energy is a weak 52. It’s surfable, but just barely. Then again on Saturday morning, the 12th of September, we get another glassy morning with 2 ft at 8 seconds from the W (energy 42). Still tiny. The only real flicker of hope comes on Sunday morning, the 13th of September. We have a clean, offshore breeze from the ESE, with waves at 2 ft from the W at 9 seconds. The energy is 95. It's not going to be epic, but with the right bank and that light offshore wind, you might find a crumbly little wave to yourself. That’s the best on offer, and even that is a real struggle session.
Don't hold your breath for the rest of the month. The second week is a write-off with persistent onshore winds and tiny, weak swell. The end of the period on Monday the 21st shows a jump in size to 4 ft, but it’s short-period (8 secs) and hammered by a 16 mph onshore wind. It's not recommendable.
So, the call is this: Thursday morning the 10th for a glassy paddle, or Saturday morning the 12th for the same glass, or hold out for Sunday morning the 13th for the only clean, offshore wind window. It’s going to be a long wait for a mediocre wave.
Rusty, signing off.
