The Lowdown
Right then, let’s have a proper look at what’s on offer here. The main event is Barvas (Lewis) – a reef break that’s fairly consistent, exposed to the northwest swell, and works best with a swell from the NW. Water temp is sitting at 57°, which is pretty much normal for this time of year – nothing unusual there.
We’ve got a bit of a wait for anything worthwhile. The first few days are a write-off – poor surf conditions, weak energy, and messy wind. Saturday the 1st and Sunday the 2nd see some small NW swell but the wind is all over the place. Sunday afternoon does go glassy with a light NNW breeze, but the swell is only 4 ft with a short 8-second period and weak energy (292), so it’s rideable but nothing special.
Monday the 3rd and Tuesday the 4th are a right-off – cross-off winds and tiny swell, energy dropping to 70 or less. That pattern keeps up until Thursday the 8th, when we finally see some size. Saturday the 8th morning brings 6 ft W swell with onshore wind, and by afternoon it’s 8 ft but still onshore – that’s getting big and messy, more for the brave than the average surfer.
Sunday the 9th is the real standout: an 8 ft WNW swell with strong energy (1,135) but cross-on winds and choppy conditions – that’s big, powerful, and only for experts. The 8 ft+ is too much for beginners, and the period is 9 seconds, so it’s a bit short and bumpy. That’s a day for the experienced.
The forecast gets a bit wild in the second week. Wednesday the 14th afternoon is a highlight: 6 ft W swell, glassy wind, and energy at 519 – that’s clean, decent size, and the glassy conditions make it a proper session. But the wind is only 3 mph from the NW, so it’s light and clean. That’s the best on offer, but it’s a long way out, so keep an eye on it.
The rest of the second week is a mix of cross-on winds and choppy surf, with the exception of Sunday the 16th afternoon – 6 ft WSW swell, clean with cross-off wind, and energy at 951 – that’s another strong one, but again, a long-range call.
So, the standout is Sunday 9th for the big, raw energy, but it’s a beast. The best clean surf will be Wednesday 14th afternoon and possibly Sunday 16th afternoon – both glassy or clean, with solid swell. Crowds are rare at Barvas, so you’ll have it mostly to yourself.
