The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks at Barvas (Lewis). Got a bit of a mixed bag, so let’s break it down.
First up, the start of the outlook is a bit of a write-off. We’ve got a solid amount of swell energy rolling in, but the wind is just not your friend. For the first few days, from Thursday the 23rd through to the following week, it’s a noisy, messy picture. The wind is mostly cross-on or onshore, often fresh to strong, and the wave face is described as lumpy, choppy, or blown out. Even though the swell is pumping on the 25th with an 12ft pulse from the WNW and a combined energy of 2516, that’s serious power, but it’s all for naught with that wind. It’s a real shame; that kind of size with a clean wind would be a dream, but here it’s just a raw, churning mess. That kind of energy is strong and will be a handful, and with the wind, it’s honestly looking more like a kite session than a paddle session.
The water temperature is about what you’d expect for the time of year, nothing wild to report on that front.
Now, after a long stretch of poor conditions, there’s finally a light at the end of the tunnel. The standout window is shaping up to be the end of July and the very start of August. Mark your calendars for Thursday the 31st of July. The morning session is looking glassy, with barely a breath of wind from the SE. You’ll have a 6ft swell from the WSW, and the combined energy is a moderate 446. That’s enough to get you moving, and the glassy conditions are a major score. Then, it gets even better on the afternoon of the 31st. We’re looking at a 8ft swell from the west, period of 9 seconds, with a gentle offshore breeze from the east. That’s clean, offshore conditions with a moderate 820 combined energy. That Friday afternoon is the real gem of the whole forecast.
The Saturday morning of the 1st of August will be a bit smaller, around 3ft, but still manageable with a gentle offshore. The afternoon picks up a touch to 4ft from the NNW with a 9-second period and 309 energy. It’s surfable, but the 31st is the day to be out there.
After that little window, it fades out again. The wind shifts back, and the waves get smaller and choppier, with a few days of near gale force winds on the 3rd of August, so that’s a hard pass. The second week is slim pickings, with only a couple of marginal, small days.
To be honest, there’s a lot of waiting in this outlook. For a fairly consistent spot like Barvas, it’s a tough run. But that Friday the 31st? That’s your session. Don’t miss it.
Stay stoked,
Rusty
