The Lowdown

Alright folks, Rusty here. Let’s have a good look at what Ersary beach on Barra has in store for us over the next couple of weeks.

The overall picture is a bit of a mixed bag for the first week or so. There’s some swell around, but the conditions don’t always line up for a proper surf. We start off on Sunday the 23rd with nothing to write home about – weak WNW swell at 3ft and a cross-on breeze making it a write-off.

Monday the 24th is where it first gets interesting. We’ve got a clean 5ft W groundswell rolling in with a period of 11 seconds, and a cross-off wind. The energy is moderate (515 on the Monday morning, building to 536 in the afternoon). This is a decent window for a beginner-friendly wave – the size is manageable, the consistency is good, and the wind is keeping things tidy. This is probably the best bet in the first week.

Things get messy again from Tuesday the 25th onwards. The swell drops off, the wind turns onshore or picks up too strong, and a lot of the days are graded as poor. There’s a brief moment on Thursday the 27th morning with a clean 2ft W swell and light offshore wind, but it’s small and ordinary. The following days are mostly a washout with strong cross-onshore winds and tiny surf until we hit the end of the month. It’s a real quiet spell.

Now, hold onto your board for the start of September. On Saturday the 5th, the forecast shows a serious pulse of long-period WSW groundswell at 8ft. The wind is light offshore from the ESE in the morning. The wave energy is enormous (2113 in the morning). This is big, powerful stuff – definitely for experienced surfers only. It’s a standout for the whole period, but it’s also a fair way out, so keep an eye on it.

The next day, Sunday the 6th, gets even bigger – 13ft to 15ft from the W with a very long 11-12 second period. The energy figures are off the charts (4479 and 5384). However, the model itself says the swell is predicted to be too big for this break. At that size, a beach break like Ersary will be a washing machine, likely more interesting for the kite surfers than paddle surfers. The rest of the second week is ruled out by strong winds and messy conditions.

So to wrap it up: the pick of the early days is Monday 24th August for a clean, manageable wave. The true standout, if you have the skills and it holds, is the morning of Saturday 5th September for a powerful, clean, expert-only session. Just remember, that one is a long way off and the forecasts can wobble.

Rusty.
