The Lowdown
Right, let’s have a look at the forecast for Ersary beach on Barra.
Honestly, mate, the outlook for the next 16 days is a total write-off. There’s not a single moment in the window where the stars align for a decent paddle. We’ve got a run of poor surf conditions from start to finish, so if you’re after a wave, you’re out of luck.
The problems start straight away. This Saturday, the 8th of August, we’ve got a 10ft south-west swell, but it’s being hammered by a strong 28 mph cross-shore wind. The combined energy figures are massive – 1275 and 1480 – but that’s just raw power with no order. It’s messy cross-chop, not surfable.
Sunday the 9th is a bit smaller at 7ft, but the wind is still a fresh cross-onshore, and the quality is poor. The water temperature is about average for this time of year, nothing to write home about. By Monday the 10th, the swell drops right off to 3ft, and while the wind is light, the cross-onshore direction and small size mean it’s only marginal at best.
Tuesday the 11th through to the end of the first week stays small – mostly under 3ft – with a mix of clean but weak conditions. The swell energy is low, barely breaking 100 in some cases. Wednesday the 12th and Thursday the 13th see a bit of a bump to 4ft-6ft, but the wind is either cross or cross-off, and the surf is still rated poor. The period is around 10 seconds, so there’s some shape there, but it’s not enough to save it.
The second week is more of the same. Friday the 14th and Saturday the 15th are small and onshore, Sunday the 16th brings a bit of rain and more cross-shore wind. The swell picks up again on Thursday the 20th of August – 7ft with a 7-second period – but it’s choppy and cross-onshore. Then Friday the 21st sees 7ft and a strong 25-31 mph cross-shore, again messy.
The biggest swell of the window hits on Saturday the 22nd of August: 8ft from the west with a 10-second period, and the combined energy is a whopping 2096. But the wind is a strong 25 mph onshore, so it’s going to be a blown-out, dangerous mess. That’s expert-only territory, and even then, it’s ugly.
There’s simply nothing to recommend here. The breaks are exposed, the wind is almost always wrong, and the surf quality stays poor. If you’ve got a kite, you might find some fun on those bigger, windier days, but for a surfboard, this is a 16-day blank.
