The Lowdown

Alright folks, Rusty here. Gotta be straight with you – the next sixteen days are looking pretty bleak for Belle Ile. We’ve got a lot of time with almost nothing on the menu, so don’t be in a rush to wax up.

The pattern starts off with a real flat spell. From Monday the 20th right through to the end of the month, we’re staring at tiny little dribbles of swell, mostly 0.7 ft to 1.0 ft with the occasional bump up to 3 ft. The wave energy is laughably weak, mostly sitting in the single digits or low twenties (11 to 24 units). Even when the wind is offshore or clean, like on Wednesday the 22nd morning with a moderate offshore breeze, or Thursday the 23rd morning, it’s just not enough to push anything rideable. These are poor surf conditions, plain and simple. Not a single score above a zero in the whole run.

The first time we see any real energy building is on Tuesday the 28th, with a combined energy reading of 104 units, and then 147 units that afternoon. But the swell is still short-period (6 seconds), bumping up to 4 ft, and the wind is howling onshore from the west-northwest. That’s a messy, choppy mess – not paddle-friendly.

Things do get a little cleaner in early August, believe it or not. The morning of Monday the 3rd of August sees a moderate cross-offshore breeze and a combined energy of 105 units, with a 3 ft swell from the west-northwest at 9 seconds. That’s the best of the whole forecast, but it’s still a long way off, and with only a 3 ft wave, it’s not gonna have much punch. It’s clean, but small.

Honestly, for the whole 16-day window, there’s no standout. The conditions are consistently poor, the swell is tiny, and when the energy does pick up, the wind ruins it. If you’re a kitesurfer, the breezy, choppy afternoons around the 28th and 29th might look interesting, but for a surfer? Don’t bother. Keep your board in the garage.

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.
