Belle Ile - Les Donnants Surf Forecast and Surf Report

Alright, crew, let’s run it down for Belle Ile - Les Donnants, the river mouth break on Belle Île.

The outlook is pretty bleak for a good spell. We’re looking at a long stretch of flat, ugly conditions. The first day worth mentioning doesn’t come until Monday, 24 August. That’s a solid ten-day gap of nothing good. The swell energy is mostly puny, often well under 100 (like 21 ft-lbs, 39 ft-lbs), and the wind is just never your friend. Most mornings are cross-shore or onshore, and the afternoons get hammered by stronger gusts, leaving the ocean messy and lumpy. Water temps are normal for the time of year.

For the first week, the waves are small, running between 1 ft and 4 ft, but every single session is rated as poor surf conditions. The winds are either wrong or too strong, and the energy rarely gets going. Even the longer-period swell on 21 August (energy hits 401 ft-lbs) can’t save us—the cross-onshore wind just blows it out. That Sunday, 16 August, the energy drops to 88 ft-lbs, and it’s just tiny, weak chop.

The one bright spot lands on Monday, 24 August. That morning, we finally get a break: a light cross-off breeze from the southeast at 10 mph, giving us clean lines. The swell is 4 ft from the west with a period of 8 seconds. Combined energy (181 ft-lbs) is moderate, and the surf report calls it clean. For the afternoon, the swell picks up to 5 ft from the west-northwest, energy climbs to 244 ft-lbs, but the wind swings to the south-southeast at 15 mph, still cross-off, but stronger, so the surface gets a little more texture. Even so, this Monday is your best chance. It won’t be firing, but it’s the only rideable window in the whole outlook.

After that, Tuesday and Wednesday look rough again, with strong winds and even some rain showers showing up. So if you can, paddle out that Monday.

This is Rusty, signing off.
