The Lowdown
Right, let’s have a look at what’s cookin’ for Belle Ile over the next couple of weeks.
Well, I’ll be honest with ya, it’s a bit of a dry spell for us here. The charts are showing a whole lot of nothin’ for the first week, and into the second week it doesn’t get much better. We’re lookin’ at a run of poor surf conditions that just won’t let up. The swell is small, the wind is mostly onshore or cross-onshore, and the energy just isn’t there. You’ll be waiting a long time between sets, and even then, the waves will be messy.
For the first few days, from Saturday the 25th right through to the end of July, it’s a write-off. Onshore winds and chop are the story. The water temperature is sitting at about 68°, which is about 2° warmer than usual for this time of year – a nice little anomaly, but it won’t help the surf.
The only flicker of hope comes right at the start of August. On Tuesday morning, the 4th of August, we see a little bump of swell from the WSW at 4 ft, with a period of 8 seconds. The combined energy of all swells directed here is moderate at 245. The wind is light from the WNW, cross-on, creating small ripples. It’s a marginal, questionable tide situation, but it’s the only thing all week that’s even surfable for a determined beginner. It’s not a standout by any stretch, just the least bad option.
After that, it’s back to the same story – small, weak, and blown out. The period from the 5th to the 9th of August is all onshore wind and tiny waves, with combined energy values dropping to weak levels, like 60 or 88. The setup looks more interesting for a kite than a paddle, to be honest.
So, to wrap it up: there’s no true standout in this 16-day window. The best you can hope for is a very ordinary session on the morning of August 4th if you’re desperate. Keep the board in the car, check the forecast again, and maybe find a lake to practice your pop-ups. It’s a tough run, but it won’t last forever.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Belle Ile may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
