The Lowdown

Alright, let’s break down what’s happening at Ersary beach (Barra). It’s going to be a bit of a waiting game, I won’t lie. The start of the period is a write-off with a fresh cross-onshore wind and lumpy, messy waves. Tuesday the 18th is a dud. We’ve got a long gap of a few days with no real surf to recommend.

The first flicker of something clean comes on Wednesday the 19th. The swell is a bit lumpy at 7ft from the WSW with a period of 10 seconds, but the wind is a gentle cross-offshore, and the combined energy is moderate (904). The conditions are clean, but the forecast is marginal. It's not the best quality, but it's the first time you'll get a clean look. The swell is over 5ft, so it’s not a beginner’s session.

The next real standout is a bit of a surprise. The morning of Sunday the 30th of August. There’s a solid 10ft groundswell from the west, with a period of 9 seconds, pushing in with strong wave energy (1404). The wind is a moderate cross-offshore, keeping it clean. The swell is big, well over 8ft, so this is for experts only. The water temperature is about average for the time of year here.

Then, on Tuesday the 1st of September, we get another big pulse. The swell is 8ft from the WSW, with a period of 10 seconds and very strong wave energy (2125). The wind is onshore, which is a shame, but the forecast is marginal. The swell is too big for beginners.

Honestly, the best on offer is that Sunday the 30th of August morning. It’s the only time the stars align for clean, big waves. For the rest of the period, there’s a lot of poor surf, and the big swells that do come in on the 1st and 2nd of September are either blown out or just too big for this exposed beach break. If you’re an expert, pencil in that Sunday the 30th. Otherwise, it’s a quiet diary.
