The Lowdown
Alright, Rusty here. Let’s chew the fat on what’s coming for the next couple of weeks for our coastline at Rade de Croisic.
Honestly, it’s a pretty rough stretch. We’ve got a long, lean period with very little worth paddling out for. From Tuesday the 18th of August through the end of the month, the surf is mostly poor, with a lot of onshore wind and choppy, lumpy conditions. The only half-decent chance is on Sunday morning the 23rd of August, but even that is just barely on the radar.
That Sunday morning, we get a small 2 foot swell from the west, with a 9 second period. The wind is light, cross-off from the north-northeast, so the surface is clean. The combined energy is weak at 51. The waves are surfable but very ordinary. The water temp is about 69°, which is a bit warmer than average for this time of year.
Later in the second week, we finally get some height. On Thursday the 27th of August, there’s a 6 foot swell from the west, but the onshore southwest wind is fresh and lumpy. The energy is strong at 487, but it’s messy. The 28th and 29th of August see similar size, up to 7 feet, but again with onshore wind. That’s more of a kite surfing day than a paddle one. Into the start of September, the wind stays onshore and the surf stays lumpy.
There’s no real standout here. That 23rd of August morning is the closest we get to a clean wave. Most days, the wind is wrong and the waves are small. It’s a tough stretch, but forecasts can always turn around.
Rusty.
