The Lowdown
Alright, Rusty here again. Let's talk about Barvas in the old measurement.
This is a grim outlook, plain and simple. The whole 16-day window is a bust for decent surf. You’re looking at a long, dry spell with nothing really good to recommend until Saturday the 13th of September.
That Saturday, the 13th, is your first real chance, and it’s a marginal one. The morning has a 8ft swell from the WNW, but it’s onshore wind making it lumpy. The afternoon is a bit smaller at 7ft from the W, but still cross-onshore and choppy. The wave energy is moderate (1703), but the wind spoils it. It’s more of a kite-surfing day than a proper paddle.
There’s one other day that might be worth a look – Wednesday the 16th of September. The afternoon shows a 4ft swell from the WSW with a long period of 12 seconds, which is a proper groundswell. The wind is cross-shore, which is better. The combined energy is moderate (718). It’s still only marginal, but it’s the closest thing to a clean wave we’ve got. The long period and that direction could give Barvas (Lewis) some shape, but it’s a gamble.
Water temp is around 57°, which is about average for this time of year, so no big surprise. The rest of the outlook is just a mess of big swells with horrible wind, or small swells with onshore wind. The swell on Tuesday the 8th of September is predicted to be too big for the break, so don’t even think about it. The big groundswells, like the 15ft stuff on the 12th, are just going to be a wild, blown-out disaster.
So, what’s the standout? There isn’t one. The best you can do is the afternoon of the 16th, and even that’s a long shot. Keep your expectations low and your wetsuit zipped.
Rusty.
