The Lowdown
Alright, folks. Rusty here. Let's talk about what's happening at Ersary beach (Barra). It's a consistent, beginner-friendly little spot, wide open to the Atlantic, but the next couple of weeks are a real mixed bag. We're in for a rough stretch of weather with some serious wind and swell, so patience is the name of the game.
The outlook kicks off on Wednesday, 2nd September. The morning offers a little window of hope. We've got a clean 3ft swell from the WSW, with a period of 8 seconds, and a light offshore breeze from the ESE. The combined wave energy is moderate at 185, so it's surfable, but the conditions are just very ordinary. The afternoon goes downhill fast, with the wind picking up to 22 mph offshore and the swell dropping to 2ft—it's mostly a waste of time.
From Thursday, 3rd September, through to Thursday, 10th September, it's a write-off. The wind is relentless, mostly onshore, cross-shore, or cross-onshore, with speeds from 19 mph right up to a near gale at 34 mph. The swell gets big, from 6ft up to a massive 15ft, but every single session is marked as poor surf conditions. The combined energy spikes dramatically - reaching 6609 on Friday, 4th September - so there's plenty of raw power in the water, but it's messy, blown out, and just not enjoyable for a paddle. Honestly, for a beach break setup like this, with that much wind and that kind of swell, it's looking more like a day for the kiteboarders than the surfers.
After that long, rough gap, we finally get a break in the clouds. On Friday, 11th September, the morning is our standout. The swell is a small 3ft from the NW with an 8-second period, but the wind is a light 6 mph cross-offshore breeze from the ENE. The water is clean, and the combined energy is a very manageable 214. It's not going to be big, but it's the only window in the whole forecast where the conditions are described as "good surf conditions." The best part? Crowds are never an issue here, so you'll have the place pretty much to yourself. Get out there early.
After that, Saturday and Sunday are flat and small, and from Monday, 14th September, we're back into strong winds and poor, unrideable surf until the end of the forecast on Thursday, 17th September. The water temperature is about average for this time of year, so no wetsuit worries there.
So, to wrap it up: the one true standout is Friday morning, 11th September. It's not a classic, but it's clean, uncrowded, and all yours. Everything else in the 16-day window is a washout.
Rusty.
