The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Ersary beach (Barra) over the next couple of weeks. I’ll be straight with you – it’s a lean run.
To kick things off, we’re looking at a pretty grim start. From Friday the 17th right through to the end of July, the conditions are just not cooperating. We’ve got a solid stretch of poor surf with cross-shore and onshore winds messing up any chance of a decent wave. The swell is small and weak, with combined energy barely hitting the 100 mark for most of that first week (118 on Friday morning, dropping to 63 by Sunday). The wind is fresh and lumpy, and the period is short, mushy stuff. It’s a blank run for nearly a week and a half.
Now, the first sign of something turning up is on Saturday the 24th of July. We’ve got a big jump in swell – 10ft from the west, with a huge combined energy of 1624. That’s a lot of power, but it’s coming straight onshore with a fresh breeze, making it a total mess. That’s not for paddling; that’s a kite surfer’s dream if anything. The wave period is 10 seconds, so it’s got some push, but the wind is ruining it.
The only real standout, and I mean the only one that gets a score of 1 out of 10, hits on Tuesday the 28th of July. For the afternoon, we get a 7ft swell from the west-southwest with a 9-second period, and the wind switches to a cross-shore moderate breeze. The combined energy is strong at 896. It’s still a marginal call, but it’s the best we’ve got. This is a consistent spot, so it’s not a total shock to see a blank run, but it’s frustrating.
For the second week, the outlook stays poor. Wednesday the 29th sees a brief window of clean conditions with a cross-offshore wind and a 4ft west-northwest swell, but it’s weak. The rest of the week is just more onshore wind and lumpy, messy surf. Nothing to get excited about.
Bottom line: if you’re desperate, the Tuesday afternoon of the 28th is your best bet, but don’t expect much. The rest is a washout.
Rusty.
