The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Ersary beach (Barra) over the next couple of weeks.
First up, the water temp is sitting at 56°F – spot on for the time of year, no surprises there.
Right, the honest truth? The next week and a half looks pretty flat and messy. We’ve got a real dry spell on our hands. From Monday the 13th right through until the morning of Thursday the 23rd, there’s nothing worth paddling out for. The scores are all low, and the energy is weak. You’ll see a tiny pulse on Tuesday the 14th with a 2ft WSW swell and a period of 11 seconds, giving a combined energy of 130 (moderate), and the wind is clean from the NE at 3 mph. That’s the best of the first batch, but it’s still a very ordinary little wave. After that, it’s just onshore junk and tiny dribble.
The real standout, and the only one I’d bother marking on the calendar, is Thursday the 23rd of July. That morning and afternoon we get a jump in swell to 7ft out of the WSW, with a period of 8 seconds. The combined energy jumps right up to 527 in the morning and 829 in the afternoon – that’s strong wave energy. The wind is blowing cross-off from the SSE, so the face will be clean. However, 7ft with a short period like that is going to be a bit of a lumpy, powerful beast. It’s definitely one for the experienced crew only; beginners will be out of their depth. The crowds are listed as "never" here, so you’ll likely have the place to yourself, which is a rare treat for a spot that’s breaking.
Beyond that, the 24th and 25th drop back down into poor territory with choppy, onshore winds, and the 26th has a clean offshore from the E but only a small 4ft swell. The very end of the run, the 28th, has a bit more size but the wind is messy.
So, bottom line: don’t hold your breath for the next week. Mark your card for Thursday the 23rd for the most powerful, cleanest session of the lot. It’s a long wait, but that’s your one.
Rusty.
