The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer.

Right off the bat, I gotta be straight with you: the next week and a bit is a write-off. The setup is just plain ugly – strong winds, big messy swell, and everything lumped up. We’re looking at a real dry spell starting from the 3rd of September right through until the 11th. There’s hardly a moment where the wind and waves line up. The swell is there, but it’s blown out, cross-onshore, and just not surfable. The water temp is sitting at about 57.7°, which is pretty much bang on average for this time of year, so no surprises there.

The first real glimmer of hope – and I mean a real one – comes on the morning of Saturday the 12th of September. Barvas (Lewis) is the only game in town, and honestly, it looks like it might just fire. We’ve got a solid 11.5 ft swell rolling in from the WNW with a long period of 13 seconds. That’s proper groundswell, tons of energy (4184), and it’s the kind of power that makes a reef break like Barvas start doing its thing. The wind is light, a gentle breeze cross-on, so it’ll be a little textured but not blown out. Now, a word of caution: this is a beginner-friendly reef break, and 11.5 ft is pushing it for the less experienced. You’ll want your wits about you. The crowd is rare, so you’ll have plenty of room to work. The swell direction is a perfect match for the optimum NW direction. This is the standout, no question. The afternoon stays clean too, with 9.8 ft and a 12-second period, though the wind goes even lighter. It’s a big day.

After that, things get messy again. The 13th and 14th drop back into poor conditions with more wind and chop. The 15th and 16th stay average, with moderate cross-shore wind and lumpy surf. However, on the afternoon of the 16th, the swell bumps up to 9.8 ft from the WSW with a 10-second period, and the wind is still fresh cross-shore, so it’s messy. The file says it’s too big for the break with favorable wind and tide, but the swell is just too much for a clean ride. The 17th and 18th are a washout again, with strong winds and a massive 13.1 ft NW groundswell on the 18th morning, but with 22 mph winds, it’s a no-go.

So, the one real window is the 12th. If you’re free, get out there. It’s the only stand-out in a long stretch of dross.
