Updates in hr min s Forecast update imminent
Alright, Rusty here. Let’s get into it for Ersary beach on Barra.
Honestly, this forecast is a bit of a heartbreaker. For the next week and a half, the wind and conditions just aren’t cooperating. We’re looking at a long, frustrating stretch of poor surf quality before things finally clean up. The water temp is sitting at 56°, which is pretty much right on the money for this time of year.
The opening days are a write-off. Thursday the 2nd and Friday the 3rd have solid swell – around 7ft to 6ft – but it’s coming with a wicked 19 mph cross-onshore wind, making a mess of things. The wave energy is moderate, but it’s not rideable in those conditions. Saturday the 4th is uglier still with a 8ft swell and 25 mph winds, and that pattern drags on through to Tuesday the 8th.
There’s a glimmer of hope on Wednesday the 8th afternoon. The wind finally drops and goes cross-offshore, cleaning up the 4ft swell from the WSW. It’s small, and the period is a short 10 seconds, so it won’t have much power, but it will be clean. You could get a few little ones. Thursday the 9th and Friday the 10th look similar: clean, small waves around 4ft to 4ft, but still nothing to write home about.
Then a real tease comes on Monday the 13th. A solid 6ft to 6ft groundswell from the WSW with a long 13-second period rolls in. That’s proper energy. But the wind is cross-shore, and because we’re at a beach break, that long period is going to make the waves fat and straight. It’s marginal surf at best.
If you have to pick a moment, the cleanest and most rideable stretch is Wednesday the 8th afternoon through the weekend of the 11th and 12th, but it’s all small stuff. The only standout for size and potential is Monday the 13th, but that wind and the beach break setup keep it from being a true winner. It’s a frustrating outlook.
Rusty.
