Belle Ile Surf Forecast and Surf Report

Right, let’s have a look at what Belle Ile’s got cookin’ over the next couple of weeks.

First thing you’ll notice is a bit of a slow start. Friday afternoon is a write-off – messy onshore wind and weak energy (193) – so don’t even bother paddling out. The real action kicks off Saturday morning, September 5th. That’s where the window opens.

Saturday morning is the standout of the whole outlook. We’ve got a clean 5ft swell out of the WNW, and the wind is offshore from the east at 9 mph. That’s the kind of combo that’ll have the bank looking smooth. The period is 12 seconds, so there’s proper groundswell energy in the water, and the combined energy is a solid 539 – that’s moderate but punchy. This is the best session on offer, no question. The water is sitting at 67°F, which is a touch warmer than normal for this time of year, so you might get away with a thinner spring suit. Be aware that crowds are sometimes an issue here, so get down early.

Saturday afternoon is still sweet – the wind drops to glassy, the swell holds at 4ft and the period stretches to 13 seconds. That’s dreamy, clean conditions with moderate energy (506). If you can’t make the morning, the arvo is a very close second.

Sunday morning the 6th sees the wind swing back offshore, but the swell drops to 3ft and the energy is down to 146. It’s rideable but nothing special. Sunday afternoon gets choppy with cross-onshore wind, so that’s a no-go.

From Monday the 7th through to Thursday the 11th, it’s a write-off. Onshore winds, rising swell heights but with poor conditions – that 5ft to 6ft stuff on Monday and Tuesday is coming in with onshore wind and high energy (964-1032), but it’ll be a messy, blown-out mess. The period is long (13-14 seconds) but that’s wasted with the wind.

There’s a gap here of several days with no real recommendations. The next flicker of hope comes Saturday morning, September 12th. Offshore wind from the ENE at 9 mph, swell 3ft, period 10 seconds, and energy at 225. It’s a small, clean session – nothing to write home about, but if you’re desperate, it’s better than the junk that came before.

Sunday the 13th afternoon is glassy, but the swell is only 2ft, so it’s a longboard day at best.

The second week is a bit of a mixed bag. From the 14th onward, the swell stays small (1.0ft to 5ft) and the wind is mostly cross-offshore or cross-on, but the quality is poor or marginal. The last few days – the 17th, 18th, and 19th – see a bump in swell to 5ft-5ft, and the wind is cross-offshore, but the energy is moderate to strong (367-450). The period is 10 seconds, so it’s not groundswell quality. Honestly, it looks more interesting for a kite than a paddle on those days.

So, lock in Saturday morning, September 5th for the best surf of the window. Clean, offshore, solid groundswell, and glassy conditions. The rest of the fortnight is mostly waiting for the next proper system.
