The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Ersary beach on Barra. It’s a bleak picture for the next couple of weeks, I’m not gonna lie to you. This exposed beach picks up a lot of swell, but we’re cursed with wind, wind, and more wind from the wrong direction. The water is sitting at 58°, which is about average for this time of year, so no surprises there.
The first real chance to get wet is a long way off, on the morning of Saturday, 1st August. We’ve got a long gap of nothing but poor conditions before that. The swell is tiny, only 3ft from the west, with a short period of 7 seconds, so weak, disorganised energy. But, and this is a big but, we finally get a light offshore wind from the east, 15 km/h, keeping things clean. It’s surfable, but only just. It’s a beginner-friendly break, consistent, and never crowded, so if you’re learning, this is your window. The afternoon sees the swell drop to 3ft, still clean, but it’s a real small-wave session.
Beyond that, it’s back to the same old story. The wind swings onshore again for the rest of the period, with a few bumps of swell in the 5ft to 8ft range, but they’re all blown out or cross-choppy. The 8th of August has a big pulse of 8ft west-southwest swell on Saturday afternoon, but the wind is howling onshore at 30 km/h from the west-northwest, making it a complete mess. That’s kite-surfing territory, not paddle surfing. The 9th of August has a 7ft north-west swell with a 40 km/h onshore wind – again, unsurfable for a decent wave.
Honestly, the only standout in this whole 16-day window is that Saturday morning, 1st August. It’s the only time the stars align with clean, offshore conditions. The swell is small, but it’s clean, and that’s gold around here right now. Everything else is a write-off.
Rusty.
