The Lowdown

Right then, let’s have a look at what’s on the cards for Ersary beach on Barra. To be honest, the next week and a half is mostly a write-off. We’ve got a heap of strong wind and messy conditions. The water temp is sitting at 58°, which is pretty much what you’d expect for this time of year, so no surprises there.

The first sniff of anything decent doesn’t show up until Sunday the 20th of September. Through the week before that, we’re looking at an awful lot of blown-out, lumpy slop. On Thursday the 18th, the swell is pushing 10ft but it’s cross-onshore and lumpy; that’s more of a kitesurfing mission than a paddle session, if you ask me.

So, the standout window starts on Sunday the 20th. That morning, we’ve got an 8ft swell from the west with a very long 12-second period, and the wind is just a slight air from the west, so it’s light cross-onshore with small ripples. The combined energy is big, at 3427. It’s a bit of a beast, but it’s still going to be lumpy from the previous days. The real gem is that afternoon: the swell drops a touch to 7ft from the west-southwest, still with that long 12-second period, and the wind goes glassy. The setup there looks excellent for experienced surfers. The break is exposed, but with that clean face, it’ll be a joy if you can handle the size. Be warned, it’s over 8ft, so this is strictly for the experts.

Then Monday the 21st looks very promising too. Morning brings an 8ft west-southwest swell with a 9-second period and clean offshore conditions from the east-northeast. The energy is moderate at 1340. That afternoon, the swell builds to 10ft from the west-southwest with a long 12-second period, and it’s clean with light east-northeast winds. That’s a big, powerful wave, and the forecast notes it might actually be too big for this break, but for those with the skills, it’ll be a proper session. Tuesday the 22nd follows up with solid 10ft west swell and a very long 14-second period, with clean offshore easterly winds. Again, that’s a heavy groundswell, best for experienced chargers. The break is exposed, so it’ll cop the full force. Through to Wednesday the 23rd, the swell drops back to a more manageable 7ft from the west with a long period, still clean.

Overall, the first real quality is on Sunday the 20th afternoon. The other strong days (Monday 21st to Wednesday 23rd) are all quality but the swell is big and powerful, so it’s not for everyone. There are no crowds to worry about at Ersary – it rarely gets busy, so you’ll have plenty of room to pick off the sets.

The long-range stuff looks promising, but it’s still a way off, so keep an eye on the wind.
