The Lowdown

Alright folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty grim for a proper surf. We’ve got a long stretch of small, weak junk ahead, and it’s going to take a while before we see anything that gets the heart rate up.

The window kicks off with a real whimper. Saturday the 22nd and Sunday the 23rd are basically flat, with tiny, weak swells generating barely any energy (35 and 67). The winds are onshore or cross-onshore, so it’s a complete write-off. You’re better off doing literally anything else.

There’s a brief pulse of energy that shows up on Monday the 24th. The swell bumps up to 5ft with a longer 11-second period, and the combined energy jumps to a moderate 515. Winds are cross-offshore and it looks clean. It’s still rated as marginal, but it’s the best we’ve seen so far. The swell direction is from the W, which isn’t the magic NW direction this spot loves, but it’s something. Tuesday the 25th and Wednesday the 26th will still have some clean, smaller waves, but the energy drops off fast (275, then down to 58). It’s nothing to get excited about.

Then we hit a proper dead zone. From Thursday the 27th all the way through to Sunday the 30th, it’s mostly tiny, weak surf with poor conditions. That’s a solid 4-day gap of nothing worth paddling out for. The swell does try to pick up on the 29th, but the wind is all over it, making it a choppy mess.

The next little glimpse of hope comes on Monday the 31st of August. The wind goes glassy and the surf is rideable, but it’s pretty small and weak (energy of 173). It’s clean but ordinary. We’ll take it, but it’s not a standout.

And that’s about it. The first week of September is a total write-off. From the 1st through the 6th, we’ve got onshore winds, lumpy conditions, and generally poor surf. There is some strong swell energy on the 6th of September, with a 6ft W swell and 11-second period, pushing the energy up to 740. The problem is the wind is howling onshore, and it’s just going to be a blown-out, stormy mess. If you’re a kite surfer, this might look interesting, but for a paddle surfer, it’s a hard pass.

So, looking at the whole 16-day window, honestly, there is no true standout. The best of a bad bunch is Monday the 24th and Tuesday the 25th of August. The waves will be the biggest and most organized, with clean, cross-offshore winds. It won’t be epic, but it’s your only real shot at catching something with a bit of push.

This spot, Ersary beach (Barra), likes a NW swell, and we just don’t get that direction with any quality. Also, it’s always consistent, but that just means there’s always something small and messy on offer. When it’s this flat and junky, it's best to just leave the board in the car.

Hang in there.
