The Lowdown

Alright folks, Rusty here. Let’s have a proper look at the surf outlook for Belle Ile.

Right from the start, it’s a rough patch. The waiting game begins now, and honestly, for the first week, there’s almost nothing worth paddling out for. We’re looking at a whole lot of nothing from Sunday the 26th of July right through to the end of July and into the first days of August. The wind is mostly howling onshore or cross-onshore, smashing up what little swell there is. You get a brief tease on the morning of Tuesday the 28th with a bit of offshore breeze, but the swell is tiny at 3ft from the WNW and the energy is weak (107). It’s surfable, but it’s a grovel board day at best. After that, it’s back to small, messy, and blown-out conditions until we hit a real dry spell. From the afternoon of the 29th of July all the way through to the 2nd of August, the swell drops right off below 3ft and the wind is all wrong. That’s a solid gap with no worthwhile surf.

Now, hang in there, because the real story unfolds on Monday the 3rd of August. That morning is the clear standout of this entire outlook. A solid pulse of swell rolls in at 8ft from the WSW. The period is short at 7 seconds, so it’s a bit of a windswell feel, but the energy is pumping strongly (698). The wind? It’s glassy. Dead calm. That’s a major positive. The water temp is about average for the time of year at 67°F. This is the best on offer, and it’s a proper window for a fun session on a beginner-friendly wave if you’re happy with a bit of a shorter-period bump.

After that high point, the conditions slip again. The afternoon of the 3rd and the 4th of August seeing the wind turning cross-onshore and the swell dropping, so it’s back to ordinary.

There is one more long-range standout to keep an eye on. On Friday the 7th of August morning, a big new swell fills in at 8ft from the W with a longer period of 9 seconds. The combined energy is very strong (1238). But the wind is cross-onshore and fairly choppy, so the quality is marginal. The afternoon sees the swell hit 10ft with big energy (1555), but the wind howls onshore at 22 mph. That’s big, wild, and messy—only for the experts, and even then it’s a mission. The wind stays brutal through the 8th, with a near gale ripping. So that second week is a case of big, powerful, but very windy swell. A lot of that energy will just be blown out, so don’t get your hopes up too high. By the 9th, it’s all dropping off again.

So, to sum it up: the best window is the morning of Monday the 3rd of August. Get on it if you can. The big stuff in the second week has power but comes with a lot of wind hassle. Stay keen, but pick your moment.

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.
