The Lowdown
Alright, Rusty here, and I’m looking at the next couple of weeks for Ersary beach on Barra. Straight up, it’s a tough run. The swell is tiny and the wind is all over the place, so we’re gonna be waiting a long time for anything that’s worth paddling out for.
The first solid window doesn’t really show up until the morning of Sunday, August 9th. Before that, from Monday the 3rd right through to Saturday the 8th, it’s just flat, messy, or blown out. The water temp is about average for the time of year, nothing unusual there.
So, Sunday, August 9th morning is where it gets a little interesting. We’ve got a 4ft northwesterly swell coming in at 11 seconds, which is a proper groundswell. It’s a bit long in the period, so at a beach break, expect it to be a little straight and hard to read, but the energy is there – combined energy is 557 (moderate). The wind is a light cross-onshore from the NNW, so it’s not perfect, but it’s gentle enough that the surf will be clean and choppy in a manageable way. The afternoon sees the swell drop to 3ft, still with the same long period, and the wind goes light cross-onshore from the north. It’s marginal, but it’s the best we’ve got. The crowd factor here is never, so you’ll have the place to yourself, but it’s inconsistent, so don’t expect a wave every minute.
Monday, August 10th morning is worth a mention too. The swell is tiny at 2ft, but we get a clean offshore wind from the ESE. The period has dropped to 10 seconds, so it’s still got some shape. The combined energy is only 100 (weak), so it’s small, but if you’ve got a log, it’ll be glassy and fun. The afternoon picks up a cross-offshore wind, so it stays clean, but the swell remains marginal.
After that, from the 11th through to the 18th, it’s back to small, windy, and poor. There’s really no standout to get excited about. The best of a bad bunch is the 9th of August morning, but only if you’re desperate for a paddle and a few small, clean waves. Keep your expectations low, and you might not be disappointed.
Rusty.
