The Lowdown
Alright, let’s get into it. Rusty here.
First off, looking at the whole 16-day window for Ersary Beach on Barra, and I’ve got to be straight with you—it’s a tough run. The first week and a half is looking pretty grim with onshore winds and messy conditions. There’s a real gap of poor surf quality stretching from the start all the way through to the end of July. Things finally look like they might turn a corner at the very end, but we’ve got to sit through a lot of rubbish to get there.
Wednesday the 22nd kicks it off, and it’s a non-starter. We’ve got a small 3ft NW windswell at 7 seconds, but with a 12 mph NW wind putting a chop on it, it’s a write-off. The water temp’s sitting at 58°, which is pretty normal for this time of year around here, so no surprises there. The combined energy is weak (118), and it’s just not worth paddling out.
Honestly, from Wednesday the 22nd right through to Wednesday the 30th, it’s every day the same sad story: onshore or cross-onshore wind, lumpy and choppy surf, and scores that tell you to stay on the beach. The swell tries to get going around Friday the 24th with a 7ft W swell, but that 22 mph WSW wind destroys it. The combined energy mods up to 559, but it’s a kite-surfing day, not a paddle one.
Saturday the 25th sees the swell jump to 8ft from the west, with a 10-second period and combined energy hitting 2060 (very strong), but it’s blowing 25 mph from the WNW. That’s expert-only territory at best, with the offshore wind making it look heavy and wild, but honestly, that’s more for the kamikaze crew.
Finally, on Thursday the 30th of July, we get a glimmer. The afternoon shows a light 3ft W swell, period 8 seconds, and the wind swings around to light ESE at 6 mph, going offshore. Conditions go clean. The energy is still low (117), but it’s the first time you won’t be fighting a washing machine. It’s “surfable but ordinary,” and even then, it’s just tiny waves for a longboard or a foiler.
Then on Friday the 31st of July, the afternoon brings a stand-out event. The swell jumps to a solid 10ft from the WSW with a 9-second period. The wind is SSE at 19 mph, which is cross-offshore here, keeping it clean. Combined energy is a massive 1655 (very strong). Now, here’s the catch—the guidance says it’s predicted to be too big for this break. This is an exposed beach, and 10ft with a short period will be a closeout on a bad day, or maybe just a peaky mess for experts only. The conditions are clean, but you’d need to be a local charmer to know where to sit. It’s the most interesting swell of the window, but it’s not for the faint-hearted.
After that, the first week of August slides back into mediocrity. Some moderate cross-shore winds, mixed swell directions, and the scores drop off. There’s a bit of a pulse on Monday the 3rd with 7ft from the WNW, but it’s cross-shore and choppy. Tuesday the 4th morning has 8ft and a gentle cross-onshore wind, but the period is short at 8 seconds, meaning lumpy conditions again.
The absolute best session in this entire outlook, if you can call it that, is Thursday the 30th of July afternoon for the clean, tiny waves, or Friday the 31st July afternoon for the big, clean, expert-only swell. For the average surfer, there’s not much to get excited about. It’s a long, quiet spell.
Stay patient, lads. Conditions can change quick around here.
