The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
Honestly, we’re in for a lean stretch at Rade de Croisic. The first few days are a write-off. Monday the 31st of August is a total washout with a strong onshore breeze and a messy 7 ft W swell. The water temp is sitting at 67°F, which is about average for the time of year, so nothing to complain about there, but you won’t want to be in it for the waves.
Things start to look a little more promising towards the end of the first week. The real standout of the whole forecast is Saturday morning, September 5th. We’ve got a clean 3 ft W swell, but here’s the kicker – that swell is a proper groundswell with a 13-second period. The wind is light and cross-off from the NNE, which will keep the surface smooth. The energy is moderate (260), enough to get you moving. This is the best window on offer, no question.
Then again on Tuesday morning, September 8th, there’s another clean shot. The swell is similar at 3 ft from the W, period 12 seconds, and a light offshore from the E will keep the faces clean. Combined energy is moderate (229). This is a solid second option, but the Saturday morning slot is the one to circle.
Beyond that, the second week looks pretty uninspiring. There’s a brief window of glassy conditions on Saturday afternoon, September 12th, with a weak 2 ft WSW swell, but the energy is low (72) and the period is short, so it’s not going to light anyone’s fire. The rest of the time is plagued by onshore winds, small swell, or both.
So, to keep it simple: if you’ve got a window, be on the water for the morning of Saturday the 5th of September. That’s the best we’ve got.
Rusty.
