The Lowdown
Alright folks, Rusty here. Let's get into it for Ersary Beach, Barra.
Right now, the outlook is pretty quiet for a while. We’ve got a long stretch coming up with no real action to get excited about. The first few days are basically a write-off, with nothing worth paddling out for until at least the 24th of July.
Looking at Tuesday morning the 14th, it’s glassy with a tiny 2ft WSW swell pushing in with a period of 11 seconds. The wave energy is weak (130), and it's a beginner-friendly wave. Honestly, it’s surfable but very ordinary. The water temperature feels about normal for this time of year.
We then have a big gap with no real recommendations. From the 15th right through to the morning of the 24th of July, conditions are consistently poor. It’s a dead run of small, weak swell and messy wind. You'll see some days with a little more height, like Friday the 17th with a 4ft windswell, but the period is a short 5 seconds and the wind is cross-shore. It’s not worth your time.
The only standout in this entire forecast window is the morning of Friday, the 24th of July. This is the one to circle on the calendar, but it comes with a major caveat. The swell is forecast to be a solid 12ft from the west, with a long period of 13 seconds. That's a proper groundswell. The combined wave energy is pumping hard (6154). However, for a beginner break, this is way too much. It’s an expert-only day. The wind is cross-onshore at 12 mph, so it won’t be perfect, but the raw power is there. If you’re experienced and looking for a big session, this is your chance for some real size. It’s a long way off, so treat it as promising but keep an eye on it.
After that, the 25th still holds some size, around 7ft from the west, but it looks marginal with cross-shore winds. The end of the month gets blown out with strong winds.
For the most part, it’s a quiet stretch at Ersary. Save your energy for that 24th if you’ve got the skills.
Rusty.
