The Lowdown
G’day, I’m Rusty. Let’s have a look at what Belle Ile has cookin’ for us over the next couple of weeks.
Well, I gotta be straight with you – this outlook is a real rough one. For the first week and a half, there’s barely a whisper of decent surf. From Thursday the 23rd right through to the end of July, the swell is tiny, mostly under 3ft, and the wind is either onshore or cross-shore, making those little waves a messy, choppy, poor excuse for surf. The only mornings that even look surfable, like Monday the 27th and Tuesday the 28th, are still ordinary – just not worth paddling out for. The combined energy barely cracks 100 (232) on Monday morning, but it’s a cross-shore wind and the swell is just 4ft from the WNW. Not a standout by any stretch.
There’s a serious gap of no-good surf here. The first real pulse of energy shows up on Sunday the 2nd of August. Swell picks up to 5ft from the west, with combined energy jumping to 327 – that’s moderate energy and the biggest swell we’ve seen. But here’s the kicker: the wind is onshore and the surf is still listed as “poor surf conditions.” That’s a tough one. For a beginner break like Belle Ile, 5ft is pushing it for a learner, and with the wind on it, it’s gonna be a messy, lumpy affair. The period is a short 8 seconds, so it’s a weak, choppy windswell. Not the clean, lined-up stuff you’d want.
The absolute best option, and I mean the only one that gets my blood pumping a little, is the morning of Tuesday the 4th of August. The wind is light from the west, almost glassy, and the swell is a tiny 1ft from the west with a 9-second period. The combined energy is a weak 38 (low energy). It’s a small, clean, glassy morning. The water temp is about 69°F, which is a touch warmer than normal for this time of year, so it’s a nice, comfortable paddle. Look, it’s not a big day, but for a beginner spot, that light wind and clean conditions make it the best of a very poor bunch. The crowds are only “sometimes” a problem, so you might have it nearly to yourself. But honestly, for the rest of the 16 days, it’s a bust. The swell is too small, the wind is often wrong, and the whole setup looks more interesting for a kiteboarder on those bigger, windier afternoons than for a surfer.
Stay patient, mate. The forecast can change.
Rusty.

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.
