The Lowdown
Alright folks, Rusty here. Let's talk about what's coming up for the Rade de Croisic over the next couple of weeks.
To be honest, it’s a slow start and a bit of a mixed bag overall, but there are a couple of windows that look worth getting excited about. The first few days are a write-off for any proper surfing. We've got lumpy, choppy onshore slop with tiny, weak windswell that’s not worth paddling out for. That’s the Tuesday 15th through to the weekend, with no recommendations at all.
Things start to get a little more interesting heading into the following week. On Monday the 21st morning, we might see some tiny, clean waves – 2 ft from the west – with that light ENE cross-offshore breeze. Not going to set the world on fire, but it's a start, and the wave energy is pretty weak. The real standout, the one you want to circle on the calendar, is Wednesday the 23rd. The morning looks excellent. We’ll see a clean 4 ft groundswell from the west (14-second period) with a nice offshore wind from the ENE. The wave energy is in that moderate zone. The water is sitting at 68°, which is a touch warmer than normal for this time of year, so you won't need the thickest wetsuit.
After that, it drops off again into cleaner but tiny surf through the rest of that week, with offshore winds but not enough swell to get excited about. There’s a promising uptick for the morning of Saturday the 26th, with a long-period groundswell coming in from the WSW at 3 ft but with a very long 15-second period and a moderate offshore wind. The wave energy is moderate, and it should be glassy and clean.
Then we get a real dose of power heading into the last week of September. Monday the 28th morning shows a solid 6 ft swell from the WNW, but with a strong onshore wind and very high energy. The setup looks more interesting for kite surfing than paddle surfing as it will be a messy, blown-out mess. The best chance for the very end of the window looks to be Wednesday the 30th morning. The swell should be a more manageable 4 ft from the WSW with a light offshore wind from the ENE and moderate energy. It should offer up some clean, fun-sized waves to finish the forecast period.
To sum it up: If you can, get out on the morning of the 23rd; that’s the pick of the bunch right now. The 26th and 30th mornings also look promising but with longer-period swells that need the right tide at this break.
Rusty, signing off.
