The Lowdown

Alright, I’ve had a look at everything for Belle Ile over the next 16 days, and to be honest, it’s a pretty grim stretch. The water temp is sitting around 68°F with a slight anomaly of 2°F, so basically normal for this time of year. But that’s about the only thing that’s normal – the surf is just not showing up.

Right from Saturday the 1st through to about Friday the 13th, there’s nothing. I’m talking flat, weak, messy conditions day after day. Swell heights barely tickle 3 ft, wavelengths are short, and the combined energy stays low, mostly under 100. Even when we get a bump or two, the wind is onshore or cross-onshore, tearing it up. There’s a solid run of poor surf, with only a few brief windows of clean-ish conditions. Saturday morning the 1st offers a tiny 1 ft W swell under cross-off NE winds, but it’s flat and weak – energy is just 59. Then again on Sunday the 2nd, similar story – 2 ft, weak, cross-off but no size. On Thursday the 6th the swell pushes to 4 ft – that’s the biggest for the whole run – but the wind is cross-onshore, energy climbs to 131, and it’s still classified as poor surf. Not worth paddling out for.

Things look a little more promising on the 13th. Thursday morning the 13th has a 2 ft W swell, period 9s, energy at 102, and a light NE cross-off breeze. Conditions are clean – it’s the first time we get a “surfable” rating. But it’s still small, and it’s a long way off. Then on the 11th, we get a couple of glassy moments: Tuesday morning brings a fresh offshore ENE breeze at 19 mph, with a tiny 0.7 ft WNW swell, and Tuesday afternoon goes glassy from the SW at 3 mph. But again, the swell is so small it’s barely there.

The 12th morning has a moderate offshore E breeze and a 2 ft W swell with a 10s period – direction is okay, but the energy is just 52 and the waves are tiny. There’s a gap of around 12 days with no real surfable options before the 13th rolls around.

Honestly, if you’re looking for a standout, there isn’t one. The best I can say is keep an eye on Thursday the 13th morning – if the wind holds, that 2 ft clean swell might give you a few fun little rollers, but don’t expect much. After that, it’s back to wind and chop through the rest of the period.

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.
