The Lowdown
Alright folks, Rusty here. Let’s have a look at what Belle Ile has in store for us over the next couple of weeks.
Honestly, I’ve gotta level with you – this is a pretty grim run. The whole 16-day window looks bleak, with no real surf to get excited about. The first week is a write-off, and the second week doesn’t offer much more. We’re looking at a long, dry spell with hardly any decent waves.
The only real window that even *might* get your attention is Tuesday morning, the 28th of July. That’s your best bet. Belle Ile itself will have a small 3 ft swell from the WNW, with a period of 10 seconds. The wind will be offshore from the east at 12 mph, which should keep things clean. The water temperature is sitting at 68°, which is about average for this time of year. The combined swell energy is weak (107), so don’t expect much push. It’s more of a longboard or a foamy kind of day. Even then, the conditions are just “ordinary” – it’s surfable, but nothing to write home about.
After that, it’s basically all downhill. From Tuesday afternoon through the rest of the first week and into the second, we’ve got a mix of tiny swell, onshore winds, and messy conditions. The swell barely gets above 2 ft for most of it, and when it does get a little bigger, like on Sunday the 9th of August, the wind is howling from the NW at 19-22 mph, making it a cross-onshore mess. The combined energy on that Sunday afternoon is moderate (244), but it’s not going to be any fun to paddle into.
There’s not a single standout in this whole period. The swell is small, the wind is wrong, and the quality is poor. If you’re a kite surfer, you might have some fun on the windier days, but for a paddle surfer, I’d say just leave the board in the car and go for a walk.
Rusty.

Information about the Belle Ile Surf forecast
The above surf forecast table for Belle Ile provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Belle Ile can be found by selecting the local surf guide option on the grey menu. Our Belle Ile surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Belle Ile) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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. 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.
