The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s happening on Barra. To be straight with you, the next couple of weeks are looking pretty grim for a paddle. Ersary beach is a consistent spot, but it’s a real exposed beach, and the wind gods are just not playing ball for a long stretch. Most of the time, the wind is howling onshore or cross-onshore, leaving the ocean a messy, lumpy chop. It’s a tough watch.
We’ve got a bit of size early on, with a 6ft swell from the west on Sunday the 26th, but it’s junk. The wind is a solid 12 mph onshore from the NW, and the wave energy is moderate (627). The water is a mild 58°, which is bang on average for the time of year. Not a single session in the first two weeks gets a green light for surfing; it’s all poor surf conditions. The swell sticks around, but the wind just tears it apart. By Tuesday the 28th, the swell drops to 1.0ft, with a messy 25 mph cross-shore. It’s just not worth it.
The whole first week and into the second is a write-off. There’s a big gap here with no real recommendations. Things get interesting, but only a little, on Sunday the 9th of August. The morning is glassy but tiny at 1.0ft. The afternoon session on the 9th is the only time in the whole 16-day window that the report says it’s actually surfable, and I’ll tell you, it’s nothing to write home about. The swell is 3ft from the southwest, with a period of 9 seconds, and the wind is a light offshore from the SE. The combined energy is weak (121). The water temp is still that same mild 58° with no anomaly given. It’s not a standout by any stretch, but it’s the only clean window you’ll get. The waves will be small and a bit weak, but at least the surface will be clean.
The rest of the 10th of August sees the wind pick back up, and the swell bumps up to 6ft, but it’s all cross-shore and lumpy again. So, a long, frustrating gap for the surfers, but if you’re desperate for a paddle, that Sunday afternoon on the 9th is your only sliver of hope. Keep your eyes on the charts, but this one is a tough read.
Rusty.
