The Lowdown
Alright folks, Rusty here. Let's break down what's shaking at Ersary beach on Barra.
First off, I've got to be honest – the next week and a half is a total bummer. From Wednesday the 29th all the way through to the 7th of August, it’s a long stretch of poor conditions. The wind is mostly onshore or cross-onshore, the swell is tiny and junky, and there's just no quality to speak of. You’d be better off staying home.
The only faint glimmer in the first week is on Sunday the 2nd of August. The morning shows a little pulse with a 4ft swell from the WNW and a period of 8 seconds. The combined energy is moderate, and you’ve got a light cross-onshore wind from the NNW. It’s not great, but it’s the least bad option if you’re aching for a paddle. The water temp is about 58°, which is pretty normal for this time of year.
Now, brace yourselves, because the second weekend is a whole different story. On Saturday the 8th of August, the forecast is absolutely massive. The morning has a huge 10ft swell from the SW with a 9-second period, and it’s glassy – wind from the NNE at just 3 mph. The combined energy is strong. But here’s the kicker: that swell is predicted to be too big for this break. The afternoon gets even more insane at 13ft from the WSW with a 12-second period, and the energy is enormous. It’s still glassy, but it’s only for the experts. The swell direction is a little off the ideal NW, but with that much power, it’s a spectacle.
Then, on Sunday the 9th of August, the morning is the real prize for the experienced crew. We’ve got an 8ft swell from the west with a 10-second period, and the wind is offshore from the ESE at 6 mph. The combined energy is 1320, so it’s strong. The conditions are clean and excellent. The afternoon holds similar with a 7ft swell from the west, a 10-second period, and a light cross-offshore from the south. This is a proper groundswell with some real punch. The long period means better-shaped waves, though it might break a bit straight at a beach break. Still, if you’ve got the skills, the 9th is your day.
After that, it fades back into nothing. So, the bottom line: a tough first week, then a monster swell on the 8th that’s too big for most, followed by a clean, powerful swell on the 9th for the experts. Mark your calendars for the 9th.
Rusty.
