The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for Ersary beach on Barra.
Straight up, I'm not going to sugar-coat it. The forecast is a tough one. We're looking at a long stretch ahead with no real surf to get excited about. The whole 16-day window is basically a write-off for a proper paddle session. This isn't one of those "it'll turn around" situations; it's just a flat, blown-out run that's fairly normal for this exposed spot when the wind and swell don't line up.
We start from Wednesday, 26 August with nothing. The swell is tiny, only 1 ft from the WSW with a short period of 8 seconds, and the combined energy is a weak 32. The wind is a cross-off from the NE at 12 mph, which would normally be okay, but there's just no wave to work with. It's a "poor surf conditions" call, and that's the story for the next week and a half.
The wind stays onshore or cross-shore for most of the time, and the swell direction is all over the place. Around Sunday, 30 August, there's a hint of a 2 ft SW swell with a long period of 10 seconds, and the energy bumps up to 120 (moderate), but the wind is still cross-off, and the wave comment says "poor surf conditions." It's a tease.
We get a few pulses of bigger swell in early September, like on Thursday, 3 September, with 7 ft from the WSW and a period of 9 seconds, pushing the energy to 599 (strong). But the wind is a brutal 25 mph cross-onshore from the W. That's purely for the kite crew, not for a paddle surfer. The same goes for the 7 ft swell on Monday, 7 September – strong energy at 822, but the wind is still cross-onshore.
The water temperature is sitting at 58° which is about normal for the time of year, with a 0.9° anomaly. Nothing to write home about there.
To be honest, Ersary beach is a consistent break, but it's exposed and the wind is just not playing ball. There is no standout session, no hidden gem window. If you're desperate for a flat day walk, it's beautiful, but for surfing, I'd say give it a miss. The kite surfers might get a few howling days, but for the rest of us, it's a solid "no."
Rusty.
