Belle Ile - Les Donnants Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on offer for Belle Ile - Les Donnants over the next couple of weeks.

We’ve got a bit of a mixed bag coming. The good news is the water is sitting at a pleasant 67°, which is a touch warmer than usual for this time of year – nice for a longer session. The bad news is we’ve got a few quiet spells to get through, and the wind is going to be our main enemy for much of the period.

The standout session is hands down Saturday afternoon (5th September). The swell is a clean 4ft from the WNW with a solid 13-second period. The combined swell energy is a solid 506, which tells you there’s proper push behind it. But the real beauty here is the wind: dead calm, glassy conditions. This is the one to circle. The river mouth setup should be handling that long-period groundswell well, keeping things lined up.

Sunday morning (6th September) is your next best bet, but it’s a step down. The swell drops to 3ft from the WNW, and the combined energy is only 146. However, a strong offshore breeze from the ESE at 16 mph will keep the faces clean. It’s small, but clean.

After that, the forecast gets rough for a few days. Monday (7th September) pushes up to 5ft from the west, but it’s blown out with strong onshore winds. Tuesday morning (8th September) offers a brief window with 5ft from the west, clean conditions and light cross-offshore breezes – it’s surfable, but nothing to get too excited about.

From Wednesday (9th September) right through to around the 15th, it’s a real slog. We get a mix of small, weak swells (combined energy dropping to as low as 59) and a lot of onshore or cross-onshore wind. There’s a couple of glassy moments, like Thursday morning (10th September) with 2ft, but the energy is weak. This stretch is mostly a write-off for a decent paddle.

Things start to look up again around Wednesday morning (16th September). We see a 4ft WNW groundswell with an 11-second period and a combined energy of 290. The wind is a light cross-offshore from the NNE at 6 mph, so it’ll be clean. It’s not a blockbuster, but it’s the best thing in the second week.

Friday morning (18th September) is also worth a mention – 3ft from the WNW, clean with a light cross-offshore breeze, and combined energy of 230. It’s small but fun for a longboard or a foamie.

For the last few days of the outlook, from the 19th, the swell really fades away, dropping to 2ft and 2ft. It’s pretty flat, with very little energy to work with.

So, to wrap it up: your golden window is Saturday afternoon (5th September). Get in the water then. The first week has one or two other clean, small windows, but the second week is mostly for the dedicated. The crowds are often around here, so expect company on the good days.

Stay stoked.

Rusty.
