Belle Ile Surf Forecast and Surf Report

Alright folks, Rusty here. We’re looking at the next couple of weeks for Belle Ile, and I gotta be straight with you – it’s a tough outlook. The island is exposed to the swell, but the combination of small waves and tricky winds is making life difficult for paddlers.

The water temperature is sitting at 72°F, which is a whopping 7°F warmer than usual for this time of year. That’s very unusual – feels like a warm bath out there, but the surf just isn’t matching the tropical vibes.

We start off the forecast period on Tuesday, the 21st of July, with tiny 1ft WNW swell. The wind is a cross-offshore on Tuesday morning, keeping the surface clean, but the wave energy is weak (24) and the report says "poor surf conditions." It’s a real struggle for any decent ride. This flat, weak pattern continues through the rest of the week and into the weekend. The swell does bump up on Sunday the 26th, with a 6ft to 6ft WNW swell, and the combined energy jumps into the moderate range (265 to 376). But the wind is a mess – strong onshore and cross-onshore breezes at 22 to 28 mph. That’s going to be lumpy, choppy, and blown out. Not what you want to paddle into.

There’s a little window on Monday the 27th morning. The swell is still 6ft from the WNW, with moderate energy (508), and the wind drops to a gentle cross-on breeze. The forecast calls it "marginal." It’s not great, but it’s the closest thing to a surfable option in this run. That’s about as good as it gets.

After that, the swell fades fast. The next week, from the 28th of July through to the 5th of August, the size drops back to 1ft to 3ft and the wave energy is weak (under 145). The wind is a mix of offshore and cross-offshore on some mornings, which keeps the surface clean, but there’s simply not enough push from the ocean to generate any real waves. The period is short, between 8 and 11 seconds, so it’s mostly windswell and weak groundswell. The reports keep saying "poor surf conditions" or "surfable waves but very ordinary conditions." There’s a moment on the morning of Saturday the 1st of August with glassy conditions and 1ft, 11-second WNW swell, but it’s just too small to get excited about.

The standout in this whole 16-day window, if you can call it that, is Monday the 27th of July. Belle Ile itself will see that 6ft WNW swell, but the wind is cross-onshore, so it won’t be clean. The energy is moderate (508), but the quality is poor. For a beginner, anything over 5ft starts to get big, and with the wind blowing across, it’s not a great call. Honestly, this setup looks more promising for the kite surfers than the paddle surfers, especially on the windier days with that 6ft+ swell.

There’s a gap of several days with no real recommendations. From the 28th of July through to the 5th of August, it’s just tiny, weak waves. The conditions are clean on some mornings, but the swell is too small to surf. This is a long, quiet run for Belle Ile.

Keep an eye on the charts, but for now, maybe leave the board in the car.

Rusty.
