The Lowdown
Right then, let’s have a look at what’s coming up for Ersary beach (Barra). Honestly, it’s a pretty grim run for the next couple of weeks. The forecast is a long, hard slog of onshore and cross-shore winds, with very little in the way of a proper window for decent surf. Water temp is sitting at 58°, which is pretty much bang on average for the time of year, so no surprises there.
The first week is a write-off. From Tuesday the 28th right through to the end of the month, we’ve got persistent SW winds, mostly cross or cross-onshore, and the swell is junk. You’ll see some 6ft on Wednesday morning with a period of 8 seconds, but it’s coming with a fresh cross-onshore wind and a combined energy of 390 (moderate), so it’s just lumpy, messy, and not worth paddling out for. The whole week is a total bust.
There’s a glimmer of hope on Sunday the 2nd of August. The wind drops right out, and we get a glassy morning with a slight air. The swell is small at 3ft from the west, period 7 seconds, and combined energy of 116 (weak to moderate). It’s surfable, but very ordinary. Still, glassy conditions at a beach break in the middle of a poor run is a rare treat, so if you’re desperate, that’s your best bet. The crowds are never an issue here, so you’ll have it to yourself.
After that, it’s back to the doldrums. Monday the 3rd has a fresh offshore, but the swell is tiny at 2ft. The following days are all cross-off winds with swell barely above 2ft, and then we get a jump to 8ft on Wednesday the 5th, but that’s accompanied by a strong breeze and a period of just 7 seconds, making it a messy, choppy beast. That’s expert territory and not much fun.
The second week drags on with more of the same. Some larger swell appears around the 8th and 9th of August, with 6ft from the WSW and a period of 11 seconds, but the wind is cross or cross-onshore, and the combined energy is high (687 on the 8th, 636 on the 9th), which equals strong wave energy. That’s all for nothing though, as the conditions are just too lumpy and messy. The only real nugget is a glassy morning on the 7th of August, but the swell is a pathetic 1.0ft, so it’s barely a ripple.
All in all, the only standout is that glassy Sunday morning on the 2nd of August. For the rest of the 16-day window, it’s a tough watch. The spot is consistent, so it tends not to stay poor for long, but this run is a proper test of patience.
