Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let’s have a look at what Belle Ile has in store for us.
To be straight with you, this stretch of the forecast is a grind. We’re looking at a long, lean period with nothing good on offer. There's basically a gap of surf-less recommendations right from Tuesday the 7th of July all the way through to Wednesday the 22nd. There’s just no decent swell to work with, and most of the time the wind is either onshore or cross-onshore, messing up what little bump there is.
The only break in the frame is Belle Ile - Les Donnants (a river break, consistent but exposed). The water temperature on Tuesday morning is 67° – that’s about a touch warmer than normal for this time of year, so not bad for a dip. But the swell is tiny. The combined energy of all swells directed here is only 39, which is weak, barely a ripple. The wave height is just 2ft from the west, with a 9-second period. That’s short-period, weak stuff. The morning does have a light offshore easterly at 6 mph, so it’s clean, but there’s just no push.
Wednesday the 8th through the 9th offer the very best of a bad bunch. Wednesday morning sees a 1ft west-northwest swell with a 10-second period, energy at 54, and a gentle offshore from the east at 9 mph. It is surfable, but just ordinary. Thursday morning is similar: 2ft west-northwest, 10-second period, energy at 75, and a clean offshore easterly. You could get a few grovelly ones on a longboard if you’re desperate, but there’s no standout here.
After that, the wind picks up and the swell drops back to nothing. By Wednesday the 22nd, the swell tries to bump up to 5ft, but it’s a 6-second period windswell from the west, energy jumps to 204, but it’s blown out with a moderate cross-onshore southwesterly at 12 mph. That’s a messy, lumpy mess – more of a kite session than a paddle.
Honestly, there’s no surf worth chasing here over this 16-day window. It’s a blank run, and that's just how this area can go for a stretch. Forecasts can change, but right now, leave the board at home.
