The Lowdown

Alright, folks, Rusty here. Let’s have a proper look at what Barvas (Lewis) has got cooking for us over the next couple of weeks. I gotta be straight with you – this isn't going to be a straightforward run of classic clean waves. There are some serious swells on the horizon, but the wind is going to be a real handful for most of it.

The pattern is a bit of a mess. We’ve got a small window of rideable, but nothing special, to kick things off, and then a long stretch of big, powerful, but wind-affected surf. For the first few days, the conditions are going to be a real mixed bag. Sunday the 13th, we’re looking at a 6ft swell from the WNW with an 11-second period, but a cross-shore wind is going to put a chop on it. The combined energy is moderate (1025), but it’s marginal at best. Monday the 14th is pretty much the same story, with a similar size swell but even shorter period, so it’ll be a bit weaker and more disorganised.

Now, from Tuesday the 15th right through to the end of the week, it’s pretty grim. Strong winds are going to mess up what could be some great swell. The swell sizes keep climbing, but the wind is just too strong and from the wrong angles. It’s just not going to be a fun paddle out there.

Here’s the thing though. For the expert crew, Sunday the 20th is the one to circle on your calendar. We’ve got a massive 16ft swell from the WNW, a long 14-second period groundswell, and the combined energy is an enormous 9781. That’s serious, powerful ocean energy. For this break, the wind and tide are predicted to be favorable, and we’re looking at clean conditions in the afternoon with a cross-offshore breeze. But I have to be real with you: at this size, this is strictly for experts only. It’s way too big for beginners, and the period is long, so those sets will be huge and powerful. It’s a point break setup, so it should handle the long period better than a beach break, but you’ve got to know what you’re doing.

After that, the swell stays huge – we’re talking 20ft to 23ft on the 21st, 23rd, and 24th – but the wind is back to being terrible, with near-gale force cross-onshore winds and a blown-out mess. The wave energy is off the charts, but it’s going to be a washing machine out there. For a few of those days, like the 20th, 22nd, and 23rd, the guidance mentions the wind and tide are favorable but the swell is predicted to be too big for this break, which is a real shame.

We then see the swell back off a touch by the 27th and 28th, down to around 7ft to 8ft with a long period. The winds are much lighter then, but it’s still a cross-onshore direction, so the surface won't be perfect. It’s a step in the right direction though, and with the energy still around the 2000 mark, it’s something to keep an eye on if the forecast improves.

So, if you’re a seasoned charger and you don't mind a bit of a wait, Sunday the 20th is your standout. It’s a big, powerful, and clean window in an otherwise messy forecast. For everyone else, you might want to wait and see how the conditions evolve towards the end of the period.

Rusty.
