Table - best surf conditions forecast for Belle Ile over the next 16 days.
Alright, Rusty here, and I’ll level with you — Belle Ile is looking pretty flat for the next stretch. We’ve got a solid run of nothing happening from Sunday the 12th through to Saturday the 26th of July.
The first week and a half is all tiny surf, from about 0.7ft to 3ft, with weak, short-period swells. The wave energy is barely there — mostly in the teens or low hundreds (combined energy). Most days are either onshore, choppy, or just completely flat. There’s a glassy morning on the 14th, but with only 0.7ft of swell, it’s not even worth paddling for. The water is sitting at 70°F, which is a whopping 6°F warmer than usual — really unusual for this time of year, so at least you’ll be warm while you’re waiting for a wave that never comes.
The only real hope shows up on Monday, July 27th. The morning bumps up to 6ft from the west, with an 8-second period and a combined energy that jumps into the strong range (512). That’s some real groundswell energy, but the wind is cross-onshore from the northwest at 9 mph, so it’ll be pretty choppy. The afternoon stays big at 6ft, but turns onshore and messy. That size is only for experts — beginners should stay well clear. Honestly, with that wind and swell, it might be more of a kite-surfing day than a paddle-surfing day.
Crowds can show up sometimes, but after this long flat spell, it’ll be empty until that Monday. Even then, it’s not perfect.
So the standout — and really the only one — is the morning of Monday, July 27th. It’s the biggest swell we’ve seen in a while, but it’s a long way off and the wind is iffy. Worth checking, but don’t get too excited.
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.
