Hey, Rusty here. Let me break it down for Belle Ile. The next couple weeks look tough – long gaps with barely a wave worth paddling for. The first session is the one to circle.
That Friday morning, July 3rd, Belle Ile is clean with 4ft of WNW swell, coming at a 10-second period – solid groundswell with some grunt. There’s a light 5 mph NE wind blowing cross-offshore, and the water temp is 68°, which is a full 4° warmer than normal for this time of year – that’s very unusual, feels like summer came early. The combined wave energy sits at 320, moderate. It’s a beginner spot, and crowds are just sometimes, so grab it while it’s quiet.
Then Friday afternoon the wind shifts onshore from the WNW at 19 mph, and the surf turns to slop.
Saturday morning, July 4th, is cleaner with 3ft of W swell, cross-off NE wind at 9 mph, energy 208 – small but rideable. Sunday morning, July 5th, drops to 2ft from the W, offshore ENE wind at 9 mph, weak energy at 101. Ordinary but clean.
From Sunday afternoon straight through to Thursday, July 16th, it’s basically a desert. Mornings have tiny swell – 1ft to 2ft – and most afternoons are wrecked by onshore WNW winds. There’s a size increase Monday afternoon, July 13th – 4ft W swell with a long 12-second period, strong 430 energy – but the wind is a howling 22 mph onshore, making it messy.
Tuesday, July 14th, sees 5ft WNW swell, 11-second period, 519 energy – powerful – but cross-on NW wind at 13 mph in the morning and onshore WNW at 22 mph in the afternoon. With that kind of chop and swell on a beach-and-reef setup, you might as well get the kite out.
Thursday morning, July 16th, is the first decent window after the opener: 3ft WNW swell, 9-second period, 123 energy, with a light 3 mph SE cross-off wind and clean conditions. Surfable, but nothing to write home about.
Friday, July 17th morning, shows 4ft from the WNW, 316 energy, but the wind is onshore again.
Bottom line: your one true shot is Friday morning, July 3rd. After that, there’s a long dry spell until maybe Thursday morning, July 16th – and that’s only ordinary. This area can be fairly consistent, so it might bounce back sooner than it looks. Keep an eye on it.
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.
