The Lowdown
Alright, let’s see what Ersary beach (Barra) has lined up for us.
To be honest, it’s a bit of a tough stretch ahead. We’ve got some real size and power coming early on, but the wind is going to be a proper nightmare. The water temp is about what you’d expect for this time of year.
The first surf we see kicks off on Friday the 24th of July, and it’s not pretty. We’re talking a 6ft to 6ft swell from the west, with a short period of 8 to 9 seconds. The wind is howling from the WSW at 19 to 22 mph, turning the surface into a complete mess with a nasty cross-onshore chop. The combined energy is moderate (487 to 505), but in those conditions, it’s a total no-go for a paddle. Honestly, this looks more like a kite-surfing day than a surfing one.
Saturday the 25th of July is a big one, but not in a good way. The swell jumps to 10ft from the west, with a period of 10 seconds. The energy is massive (1700 to 2153), but the wind is screaming onshore at 25 mph. That’s way too big for anyone but the most experienced surfers, and even then, the wind is going to blow it out completely. It’s a dangerous, messy beast.
We get a bit of a break in the wind on Thursday the 30th of July. The swell drops to 4ft from the WSW, with a short 8-second period, and the energy is weak (199). But the wind finally turns cross-offshore from the SE at 12 mph, cleaning things up. It’s the first clean surf we’ve seen, but it’s small. The best bet might be Thursday afternoon, when the wind goes fully offshore from the SE at 19 mph, with a tiny 3ft swell. It’ll be smooth, but it’s barely a wave.
After that, the swell completely dies. From Friday the 31st of July right through to the end of the 16-day window, we’re looking at flat, tiny waves, mostly under 2ft, with a lot of strong wind. There’s a long stretch of nothing rideable. It’s a pretty bleak outlook for Ersary beach, with no real standouts to get stoked about.
