The Lowdown
Alright crew, Rusty here. Let's be real, the next couple of weeks are looking pretty flat for Belle Ile. There's a big, painful gap at the start. The first few days of August are just not worth getting wet for, with tiny, weak, wind-affected slop. We're talking a solid 12 days of basically nothing worth paddling out for.
We finally see a tiny flicker of life on the 14th of August Friday afternoon. It's still small, but the wind goes light and clean, making it almost surfable. Then on the 15th of August, Saturday afternoon, we get a little bump in energy (combined energy of 117), and the wind stays light and clean. It's still small, only 3ft from the WNW, but it's the best we've got on offer. The real standout, though, is the 16th of August, Sunday afternoon. The wind goes glassy, absolute magic, with a clean 3ft from the WNW. The swell is still small, but that glassy surface will make it look way better than it is. The combined energy is moderate at 124, so there's a bit of push there. Belle Ile is a beginner-friendly spot, and with these tiny, clean conditions, it's a perfect window for learners to get some practice. The water is a touch warmer than normal for this time of year at 68°.
The next morning, the 17th of August Monday, has a clean offshore wind, but the swell is already dropping. That Sunday afternoon is your best bet. Don't expect much else; the rest of the window is a write-off.
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.
