Belle Ile - Les Donnants Surf Forecast and Surf Report

Alright folks, Rusty here. Gotta be straight with you on this one – the outlook for Belle Ile – Les Donnants is a real mixed bag of frustration and a couple of fleeting windows of absolute magic. We’re looking at a long forecast period, and for the most part, the wind is going to be the enemy.

The first real chance of anything decent doesn’t roll in until the end of the first week. We’ve got a solid gap of nothing but choppy, onshore slop before that. Starting off Wednesday the 2nd through Friday the 4th, it's a write-off. Cross-on breezes, tiny swell, and the combined energy is weak, sitting well under 100 (36 to 154). Just poor conditions.

Saturday the 5th is where things start to get interesting. The morning shows a bit of life with a 4ft swell from the WNW and a clean, cross-off breeze. The combined energy jumps to a moderate 366. But it’s the afternoon that’s the real standout. The wind goes absolutely glassy, calm and clean, with a 4ft swell, a long 12-second period, and a combined energy reading of 368. That’s the first flash of hope. The waves will have proper shape and energy, but that long period (12 seconds) might make a few sections a bit straight at a river break. Still, if you can get out, that afternoon window is the best on offer for the first week.

Sunday the 6th morning is still surfable, clean with a moderate offshore wind from the E, but the swell drops back to 2ft with a short 10-second period and energy down to 143. It’s ordinary. Sunday afternoon and Monday the 7th go straight back to junk with strong cross-onshore and onshore winds ruining everything, even though the swell is bigger (4ft-5ft with energy over 455). This period from Monday the 7th right through to Friday the 11th is a long stretch of poor, windy conditions. Swell gets big, with 7ft hitting on Thursday the 10th, but onshore winds in the fresh to strong breeze range (23-25 mph) turn it into a mess. Honestly, for most of that, it looks more like a kite-surfing zone than a paddle-surfing one.

Now, the second week holds some promise, but it's a ways out so take it with a grain of salt. The absolute standout in the entire 16-day window is Saturday the 12th of September. We’re talking a gentle offshore breeze from the East in the morning turning glassy in the afternoon. The swell is a solid 5ft to 6ft from the WNW with a nice 11-second period. The combined energy rockets up to 655-697, which is strong, moderate wave energy. This is the real deal: clean, powerful, and lined up. That’s the session to circle on your calendar.

Sunday the 13th morning is still surfable but the wind is light cross-shore, so it’s not as clean. The swell is still strong at 6ft but the period drops to 7 seconds, making it a bit walled up and less organised. The energy is still high (631), but the quality takes a hit.

Monday the 14th is another interesting morning. Glassy conditions with a 5ft WNW swell (381 energy) – that’s a good one, but not quite as powerful as the Saturday. The rest of the period from the 15th onward fades again into onshore wind and choppy conditions. A big 8ft swell hits on Thursday the 17th, but with a moderate cross-onshore breeze and the energy over 972, it’s just going to be a big, brown, lumpy mess. Not for the faint-hearted.

So, bottom line: The highlight is absolutely Saturday the 12th. That glassy afternoon with a solid, long-period groundswell is your best bet. The Saturday the 5th afternoon is also a rare gem in an otherwise windy week. The rest is a lot of waiting.
