The Lowdown
Alright, folks, Rusty here. Let's have a look at what Barra has in store for us over the next couple of weeks.
First up, straight off the bat, the pattern for Ersary beach (Barra) is a bit of a rough one for a while. The wind is howling and the ocean is a mess. We’re looking at a solid block of no-go days to kick things off. From Thursday the 3rd right through to the end of the first week, it’s all strong cross-shore and onshore wind, with swell mixed up and blown out. The combined energy is all over the place, but the quality is just not there for a paddle. There’s a big stormy stretch from the 4th with a massive 15 ft (5933) swell under a near gale – that’s for kites, not boards. A small window of cleaner conditions shows up late Saturday afternoon (5th) with a clean 6 ft (536) swell, but it’s a marginal call. Sunday the 6th is a write-off with the wind still howling. The whole first week is essentially a gap with no real recommendations.
Moving into the second week, it stays pretty grim. Monday the 7th through to Wednesday the 9th is more of the same: messy, choppy, and blown out. Early Thursday the 10th shows a 10 ft (1986) swell but with moderate cross-onshore wind, so it’s still a bumpy mess. The pattern stays poor through the 11th, 12th, and 13th with waist-to-head high swell but always battling the wind. That’s a long run of grotty surf.
Now, here’s where it gets interesting. A real standout pops up for the middle of the second week. On Monday the 14th of September, we get a proper swell. The morning kicks off with a clean 10 ft (2073) swell from the WSW under light offshore wind from the south. The notes say it might be too big for the break, and at that size with an 11-second period, it’ll be a serious, powerful wave. It’s likely only for experienced surfers. The conditions are clean though, so it’s a true highlight. This carries into Tuesday the 15th with a similar clean 10 ft (2095) swell in the morning, again under favourable light offshore wind.
The next true standout is on Friday the 18th of September. The morning brings a clean 8 ft (1672) groundswell from the west at 11 seconds. With gentle offshore wind from the east, it’s described as excellent for experienced surfers. That’s the pick of the entire outlook for the confident crew.
So, to wrap it up for Ersary beach: the first week is a total washout. The second week has a couple of big, clean days but they’re heavy and for experts only. The best option overall for a surfer who knows what they’re doing is Friday the 18th of September. The 14th is also a standout, but that 10 ft+ size is serious.
Rusty, signing off.
