The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Ersary beach on Barra.
Well, I’ve got to be straight with you – this is a tough one. Looking at the whole 16-day window, the surf just isn’t playing ball. There’s not a single day where the conditions line up for a decent paddle. The first few days have some solid swell, but the wind is all wrong. It’s a real shame, because the water temp is sitting at 58°, which is bang on average for this time of year, so you’d be comfortable in a wetsuit.
The first recommendation of any kind comes on Thursday the 23rd of July, but it’s a write-off. We’ve got a weak 3ft swell from the WNW with a short period of 6 seconds, and that combined energy is a measly 74 – weak. The wind is howling from the WSW at 12 mph, making it a cross-on mess. That’s just poor surf, plain and simple. It stays like that through Friday, with the swell building to 6ft but the wind picking up to 22 mph, keeping it lumpy and cross-onshore. The energy jumps to 529 (moderate), but with that wind, it’s all for nothing.
Saturday the 25th of July sees the biggest swell of the whole run, hitting 10ft from the west with a long 10-second period. The combined energy is a massive 1576. But hold your horses – the wind is onshore from the WNW at 25 mph. That’s going to be a messy, blown-out wall of whitewater. At over 8ft, this is expert-only territory anyway, and with that wind, it’s actually more interesting for kite surfing than paddle surfing. The afternoon drops to 8ft, but the wind is still onshore.
Sunday the 26th and Monday the 27th are still a no-go. The swell drops to 6ft, but the wind is either onshore or cross-on. The conditions are just never clean enough.
We finally get a bit of a break in the wind on Tuesday the 28th of July. The wind swings to the south at 22 mph, going cross-offshore. That’s clean! But the swell has dropped to a weak 4ft from the west, with a combined energy of only 226. The period is 9 seconds, so it’s a bit better quality, but the size is just too small to get excited about. It’s glassy, but flat.
From Wednesday the 29th right through to the end of the forecast on Friday the 7th of August, it’s a grim story. The swell is tiny, often under 3ft, and the energy is weak. The wind is all over the place – strong, cross, and even gale-force on the 4th and 7th of August. There’s just no decent surf to be had. The consistent nature of this spot means it usually doesn’t stay this poor for long, but right now, the long-range looks like a total blank. The forecast can always change, but for now, leave the board at home.
Rusty.
