Alright, Rusty here again. Let's run that down in feet and miles per hour.

Honestly, mate, it's a rough start. We're looking at a solid week of nothing really worth paddling out for. The wind is all over the shop, mostly onshore or cross-onshore, and the swell is tiny with weak energy. For the first week, from Monday the 13th right through to Saturday the 25th, it's a write-off. The best you'll get is a one-star "surfable" session on Sunday the 19th afternoon, with a tiny 2ft of WNW swell, a clean-ish cross-off breeze, but the energy is still weak (67). Not worth getting wet for.

The real story starts to build towards the end of the month. The standout is undeniably Monday morning, the 27th of July. The swell is pumping in at a solid 8ft from the west, with a period of 9 seconds. The energy reading is a massive 1060, which is proper strong. The wind is a clean cross-off from the ENE, and the guidance says the optimum swell direction is SW, so the west swell is hitting it nicely. This is big, powerful, and clean. It’s expert-only territory at that size, but for the experienced crew, that’s the session of the window. The Saturday before, the 26th, shows a 6ft swell from the WSW, but the wind is a cross-on, so it won't be as clean. Also, the water temperature is about average for the time of year here.

The Tuesday morning the 28th has some leftover energy, 5ft from the WSW, with a clean cross-off breeze, but the period is down to 7 seconds and the energy is moderate (369). It's a drop-off from the Monday.

So, don't bother with the first week. The whole run is a dud until the 27th. That Monday morning is the one to circle, but you need to be experienced to handle it. The rest is just waiting for the next system.

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.
