Right then, let’s have a look at what’s on offer for Ersary beach (Barra) over the next couple of weeks.
To be brutally honest, it’s a pretty grim stretch ahead. There’s a real gap here with no proper surf to speak of for the first week. You’ll be waiting until Thursday the 10th of July just to get a sniff of something marginal, and even then it’s not worth getting excited about. The water temp is sitting at 56°, which is bang on average for the time of year, so no surprises there.
The best of a bad bunch shows up on the morning of Thursday the 10th of July. The swell is a weak 5ft from the WSW with a period of 10 seconds, and the combined energy is only 500 – that’s moderate at best. The wind is light offshore from the NW, which will keep things clean, but it’s a real beggars-can’t-be-choosers situation. The waves will be small and weak, and the break is exposed to the NW, so that swell direction is a bit off. Expect a slow, gutless day.
A few days later, on Sunday the 20th of July, the afternoon session is about as close to a glass-off as you’ll get here. The wind is a glassy light SSE breeze, and the swell is a tiny 2ft out of the SW with a period of 12 seconds. The combined energy is a weak 80, so it’s barely moving. It’s surfable, but only just. For a beginner spot that’s consistent, this is a real flat spell.
For the rest of the period, it’s a write-off. The wind is mostly cross or onshore, the swell is tiny, and the energy readings are all in the double digits – weak and useless. The long period swell on the 14th of July (11 seconds) might sound promising, but it’s only 3ft and the wind is messy. That’s a beach setup, so a long period swell like that can break too straight and not offer much shape.
Overall, there’s nothing here that’s a standout. It’s a long, dry run for Barra. The forecasts can change, but right now, leave the board in the van.
