The Lowdown
Alright folks, Rusty here with the local rundown for Ersary Beach on Barra. Gotta be honest – this 16-day stretch is looking like a long, quiet run with hardly a proper wave worth paddling for. The pattern is set from the start and it doesn't let up.
The first snooze-worthy window arrives Saturday afternoon, August 1st. We've got a 4ft swell from the west, but it's short-period at 6 seconds. That onshore wind from the west at 15 mph is going to chop it up real good, leaving the water messy and blown out. The total wave energy reads weak at 153.
Things get quiet fast. Sunday morning, August 2nd, the wind is cross-onshore and messy. Sunday afternoon goes glassy with a light south-southwest breeze at 3 mph, but the swell is tiny – only 3ft from the west-northwest with an 8-second period and wave energy down to 100. You might snag a knee-high slosh, but it's ordinary.
After that, we hit a dead zone. From Monday, August 3rd, all the way through the first week and into the second – nearly 10 days – the swell flattens out to nothing. We're talking 1ft or less, and the wind is a mix of cross-off and onshore. No energy, no drive. It's a proper lull.
The only potential light on the horizon comes on the very last day: Sunday, August 16th. A swell builds to 7ft from the west-southwest, period at 10 seconds, and the wave energy surges to a strong 804. That's some real power. But the wind is cross-onshore from the southwest at 22 mph, so the surface will be lumpy and rough. At 7ft, this gets heavy for beginners. That Sunday afternoon even sees 8ft swell with an 11-second period and massive 1997 energy, but still the same cross-onshore breeze.
Water temp is about 58°, average for the time of year. Ersary Beach (Barra) is usually consistent, but this run is all about poor conditions and blown-out windows. That big end-of-run swell looks more interesting for kite surfing than paddle surfing with that wind. No real standout here – keep checking back; it rarely stays this flat for long.
Rusty.
