The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Alright, listen up. I've got to be straight with you – the next week and a half or so is looking pretty grim. We are looking at a real dry spell for Belle Ile. From the 16th of July right through until the morning of the 28th of July, every single session is rated as poor surf conditions. That’s a solid 12-day stretch of flat or near-flat, windy junk. The swell is tiny, mostly around 1ft to 2ft, with weak energy (mostly under 50). The wind is all over the place, often onshore or cross-off, but it doesn't matter because there's just no swell to work with. The water temp is about average for this time of year, but you won't be in the water long enough to feel it.
Now, we do have a date with some proper swell, but it's a long way off. The real action, and I mean the only real action, kicks off on the morning of the 29th of July. That Wednesday morning is the standout. The swell comes up to a solid 6ft from the West, with a period of 9 seconds. The energy is strong, hitting 537. The wind is a gentle breeze from the NNE, which is clean and cross-offshore. That makes for a clean, powerful wave. This is absolutely the best option on offer. The swell is a bit too big for beginners, but for anyone with a bit of experience, it’s time to get the good board out.
The rest of that week is a step down. The 30th of July Thursday morning is still rideable at 5ft from the West, but the energy is down to 332 and the wind is a moderate breeze, so it’s not as clean. The 31st July Friday morning has 5ft from the West but the cross-shore wind will make it a bit lumpy. So, to sum it up: you’re waiting nearly two weeks, but the 29th of July morning is the one to circle on the calendar.
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.
