Alright folks, Rusty here with the long-range look for Belle Ile.

Right off the bat, I gotta be straight with you – it’s a tough stretch ahead. The first week is a real grind with tiny, weak, and mostly onshore wind-driven junk. There’s a long, frustrating gap with nothing worth paddling out for. Honestly, for the first ten days or so, the only swells are small and the wind just won’t play ball. The one bright spot, if you can call it that, is Friday the 10th. The morning has a small 2ft swell from the WNW with a clean 10-second period and a light offshore ENE breeze. The water is a balmy 70°, which is a whopping 6° warmer than normal – that’s very unusual for the time of year and will feel like a bath. But even then, the energy is weak (94) and the overall score says it’s just ordinary. After that, it’s a long dry spell of poor conditions through the middle of the month.

Keep your eyes on the last week, though, because things get interesting. The period around the 24th and 25th of July brings a serious pulse of energy. On Friday the 24th, the afternoon sees a jump to a 5ft swell from the WSW, but that comes with onshore wind and messy conditions, so it’s a write-off. The real potential, and I mean the only true standout, is Saturday the 25th. The morning looks promising with a strong 5ft swell from the west at a 9-second period. The energy is massive, reading 441 (very strong), and it’s accompanied by a moderate cross-shore wind from the NNW. That wind direction could keep things semi-clean. This is expert territory, though – those 5ft waves pack a punch, especially on the paddle-out, and the shorter 9-second period will mean waves are a bit tighter together. If you’re a capable surfer, that morning window on the 25th is the one to chase, even if it’s a long way out.

There are no other standouts in the whole 16-day run.

Rusty, signing off.

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.
