The Lowdown
Alright, let’s get real about the next couple of weeks. I’ve been staring at the charts for Belle Ile, and it’s a bit of a rough stretch if you’re looking for quality waves. We’ve got a whole lot of small, weak surf and bumpy conditions on the horizon. The first few days are pretty much a write-off for anything decent. Honestly, it’s looking like you might be better off finding a different hobby until we get some proper swell in the water.
The water temp is sitting at 68°F, which is about normal for this time of year, so at least it won’t be freezing while you’re staring at the ocean.
The windows of opportunity are few and far between. The best we see is the morning of Friday the 7th, where we get a tiny 1ft W swell at 10 seconds, but it’s with a light cross-offshore breeze, which would make for a glassy surface. It’s not going to be big, but it might be the cleanest it gets all week. Then there’s the morning of Sunday the 9th – same deal, tiny 1ft but with a proper offshore wind, so it’ll be clean. These are the only moments with any real appeal, and even then, you’re hunting for ankle-biters. The energy in the water is minimal, with combined energy readings of 25 and 38 respectively – that’s weak stuff.
After that, there’s a big lull for several days, with almost nothing but onshore wind and dribble. The surf basically disappears from the 11th through the 16th, just tiny 0.6ft to 2ft slop with cross-shore or onshore winds. Not worth paddling out for.
Looking further out, the 17th and 18th look like they might bring a pulse of slightly bigger swell (around 3ft on the 17th) but with strong onshore winds and chop, the quality will be poor. The energy does pick up to a moderate 125 for the morning of the 17th, but you’ll be battling the wind the whole time. It’s promising that there’s some energy coming, but it’s not going to be clean surf. I’d say the setup is more interesting for the kite surfers than us paddle surfers on those days.
So, keep your expectations low. The best, and I use that term loosely, bets are the glassy mornings on the 7th and the 9th. Everything else is a lot of effort for very little reward. This is a real flat spell for Belle Ile.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
