Right, folks, Rusty here. Let's have a look at what's on the table for Belle Ile over the next couple of weeks.
Alright, to be straight with you, the first week or so is a real struggle. We’ve got a lot of small, weak swell and the wind is all over the shop. The wave energy is low, often sitting in the 40s and 60s (combined energy of all swells directed here is weak), and the swell heights are barely a ripple. The water temp is 66°, which is a touch warmer than normal for this time of year, so that’s one small mercy.
We’re looking at a gap of several days with nothing really worth paddling out for. The first few days of July are full of onshore junk and tiny surf. You’ll see a few mornings with a light offshore breeze, but the swell is just too small and short-period to get excited about – we’re talking 2ft to 2ft with periods around 8 to 9 seconds. It’s surfable, but very ordinary.
The one standout in this whole 16-day window is the morning of Tuesday, July 14th. That’s the one to circle on your calendar. The swell picks up a bit to 3ft from the WNW, with a period of 11 seconds, which is a proper groundswell. The combined energy jumps to 200 (moderate wave energy), which is the most energy we see. The wind is glassy, light from the NE, so it’ll be clean. That’s the best conditions on offer. For a beginner-friendly spot like Belle Ile, that 3ft is perfect. The break is fairly consistent, but with that quality, expect crowds sometimes.
After that, the rest of the second week looks like it’s fizzling out again. More small stuff, onshore winds, or strong offshore breezes that’ll make it hard to even get out. The 25 mph winds on the morning of Friday, July 17th are a proper blowout for surfing.
So, bottom line: the first week is a write-off. The only real window is that Tuesday, July 14th morning. If you’re keen, that’s your shot.
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.

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.
