The Lowdown
Alright folks, Rusty here. We’ve got a long look ahead at Ersary beach on Barra, and I’ll be honest with you—it’s a bit of a mixed bag with a lot of waiting involved.
Right off the bat, there’s nothing for the first few days. Thursday the 6th and Friday the 7th are a complete write-off with tiny, wind-blown junk. The swell is there on Friday, jumping up to 8ft from the WSW, but with a strong cross-onshore wind blowing at 28 mph, it’s just a mess. The combined energy hits 770 (moderate), but it’s unsurfable. The wind gets even worse on Saturday the 8th, with a near gale making it blown out and dangerous. You’d be better off with a kite than a paddleboard that day.
We finally get a little window on Sunday morning the 9th. The swell drops to 5ft from the west with a period of 9 seconds, and the wind swings light from the south, giving us clean conditions. The combined energy is 429 (moderate). It’s not a standout, but for a beginner-friendly, consistent break like Ersary, it’s the first real chance to get wet. The water temperature is about average for this time of year, so no shock there.
After that, it flat-lines again. From Sunday afternoon the 9th right through to the end of the first week and into the second, we’re looking at tiny, weak swell with poor or marginal conditions. The wind is all over the place—offshore, cross-off—but the swell is just too small, often under 3ft, with combined energy readings in the 30s, 40s, or low 100s. It’s a long, quiet stretch.
There’s a flicker of hope on Thursday the 13th with 5ft swell from the SW and a 10-second period, but the wind is a fresh cross-off, and the forecast says it’s marginal. The energy is 580 (moderate), but the tide or conditions are questionable. Not a goer, really.
The next real chance pops up on Tuesday the 18th. The morning brings 4ft from the west, a 7-second period, and a light cross-off breeze from the SSE. The energy is 244 (moderate), and the conditions are clean. It’s a small, surfable option, but don’t expect much power. The afternoon gets messy again with a fresh breeze, so the morning is the only window.
Then the final few days—Wednesday the 19th through Friday the 21st—see a solid pulse of swell coming in, with heights up to 8ft from the WSW, but the direction is all wrong for this exposed NW-facing break. The wind is howling onshore or cross-onshore at 22-28 mph, making it a complete blown-out mess. The energy readings are high (over 1200 on Wednesday morning), but it’s just for experts who don’t mind a beating, and even then, it’s not good.
The best on offer is that Sunday morning the 9th, with clean conditions and a small, manageable swell. It’s not epic, but it’s the cleanest surf in the whole 16-day window. The Tuesday morning the 18th is a distant second option for a quick paddle.
Rusty.
