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. I’ll be straight with you – it’s a real slow start, so don’t be in a rush to wax up just yet.
We’re looking at a long, quiet run from the get-go. The first few days are nothing to write home about, with tiny, weak swell and poor conditions. Wednesday the 22nd sees a tiny 1.0ft WNW swell with a period of 10 seconds, but the wind is messy and the energy is a pitiful 20. That’s just not worth your time. This flat spell drags on through the end of July. There’s a bit of a bump on Saturday the 25th with a 6ft swell showing up in the afternoon, but that’s accompanied by a strong 28 mph onshore wind, making it a complete washout for surfing. The combined energy hits 187, but it’s all just wind-driven chop.
We finally get a glimmer of hope on Monday morning, July 27th. The swell drops to 4ft from the WNW, but the real story is that glassy wind. A slight air from the NNE means the surface will be clean, and the moderate energy of 180 suggests there’s a bit of push. It’s not world-class, but it’s surfable and very ordinary. The wind stays in our favour on Tuesday morning the 28th with a gentle offshore from the ENE and a 3ft WNW swell, making for clean conditions (energy 98). After that, it’s back to small, messy, or blown-out stuff for a few days.
Now, here’s the one that’s got my attention. Mark your calendars for Tuesday, August 4th, in the morning. We’re looking at a solid 5ft swell from the west, with a period of 10 seconds and a combined energy of 472 – that’s proper moderate energy. The wind is a gentle cross-offshore from the southeast, which will keep the waves clean. The water is a touch warmer than normal for this time of year, sitting around 69°. This is your standout window. It’s not too big for an intermediate, and with that clean wind, Belle Ile is going to have some fun lines. The crowds are sometimes an issue here, so get out early.
The following morning, Wednesday, August 5th, also looks promising with a 4ft west swell and a light cross-offshore breeze from the SSE (energy 270). It’s a bit smaller but still clean. After that, the swell fades and the conditions get more ordinary again through the 6th.
So, the long and short of it is: don’t bother for the first week. The real action is that Tuesday, August 4th morning session. It’s the only true standout on the cards. Get it while it’s clean.
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.
