The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s heading our way.
Well, I’ll be honest with you, the next week and a half is looking pretty grim for a proper paddle. We’ve got a long stretch of very ordinary conditions ahead, with only a few glimmers of hope. Right now, for Tuesday, July 28th, the morning at Belle Ile - Les Donnants is the only thing worth paddling out for, and even then it’s a bit of a compromise. The wind is a clean offshore out of the east at 12 mph, which is a major positive, and we’ve got a small 3 ft swell from the WNW. The energy is moderate (107), and with a period of 10 seconds, it’s a bit of a groundswell that will offer some shape. Expect clean, surfable conditions, but it’s not going to be a world-beater. The water temp is about average for this time of year.
After that, things turn sour. From Tuesday afternoon all the way through to the end of the first week of August, we’re looking at a string of poor surf conditions. The wind is mostly onshore or cross-onshore, and the swell stays tiny or weak. There’s a gap of over a week with absolutely nothing worth recommending.
Now, if you’re patient and can wait, there’s a chance on Friday, August 7th. The morning session is the standout of the entire forecast. We’ll have a clean 5 ft swell from the WNW, with a light offshore breeze from the NE at 6 mph. The combined energy is strong (326), and while the period is short at 8 seconds, the offshore wind will make the most of it. This is expert-level size, so it’s not for beginners, but for those with the skills, it’s the best window we have. After that, it’s back to onshore wind and poor conditions for the rest of the run.
So, bottom line: Tuesday morning is your only real option for a small, clean surf. The one true standout is that Friday, August 7th morning session, but it’s a long way out and the forecast could change. For the rest, it’s a waiting game.
Rusty.
