The Lowdown

Alright, let’s talk about what’s happening around Ersary beach (Barra). It’s gonna be a quiet one for a while, mate. The water’s at 58°F, which is about average for the time of year, nothing special.

The first few days are a bust. Monday the 27th has some chest-high swell, about 5ft from the west, but the wind is a messy cross-on at 12 mph, making it choppy and poor. The combined energy is moderate (561), but it’s not doing us any good. Tuesday the 28th gets a bit bigger, with swell hitting 7ft from the southwest, but the wind ramps up to a near-gale 31 mph, making it a total mess. That’s expert-only stuff if you’re crazy enough, but honestly, it’s not worth it.

We’ve got a long stretch with no real recommendations. Wednesday through to early August is a write-off – small, weak, and cross-onshore winds. The swell drops right off, with combined energy falling below 100, and the wind stays onshore or cross-shore, keeping things lumpy. It’s going to be a tough week.

Now, there’s a tiny glimmer towards the end of the first week of August. Tuesday the 4th shows a little bit of life. The afternoon has a weak 2ft from the northwest, but the wind goes light and cross-off, and the conditions are described as “clean.” The combined energy is only 60, so it’s barely surfable, but it’s the first time we see a score of 1 out of 10. It’s ordinary, but you might find a knee-high ripple if you’re desperate.

The real standout – if you can call it that – is much further out. Friday the 7th of August has a morning push of 6ft from the west-northwest, with moderate energy (417). The wind is cross-on though, so it’s choppy again. But the afternoon session on the same day is interesting. The swell drops to 4ft, but the wind switches to a light cross-off from the south at 9 mph, and it’s clean. The combined energy is 232, and it’s the only other time we get a score of 1. It’s marginal, but it’s the best we’ve got.

After that, it’s back to small and onshore winds through to the 11th of August. The swell gets down to 1ft with poor energy, and the wind is back to being a problem.

So, there you have it. Not a lot to get excited about. The pick of the entire 16-day window is probably the afternoon of Friday the 7th of August. It’s clean, the swell is waist-to-chest high, and the period is a decent 9 seconds, which gives it a bit of shape. It’s a long way out, so don’t book the time off just yet, but keep an eye on it. The rest of the time, the board stays in the truck.
