The Lowdown
Alright, Rusty here. Let's have a look at what we've got brewing for Barvas.
Right off the bat, the next week or so is a bit of a write-off. The waves are small, the wind is messy, and the conditions are just poor. It's a waiting game. We are looking at a long stretch from now until around the 20th of August with very little to get excited about. There are a few moments with clean conditions, like Monday afternoon the 17th with a light offshore, but the swell is tiny at 3ft and the energy is weak. It's barely worth getting the wetsuit on for.
The first real standout doesn't arrive until Thursday the 20th of August. The morning is looking clean, with a NE cross-offshore breeze lining up a solid 7ft swell from the WNW. The wave energy is strong, pushing 596, so there's plenty of power in the water. That said, the period is short at 8 seconds, so it'll be a bit of a lumpy, close-out prone wave at this beach break. Still, it’s the best combo we see in this whole forecast. Keep an eye on it, but temper your expectations for perfection.
After that, the swell drops back down. The 21st of August has a cleaner afternoon with a 4ft swell, light winds, and clean conditions, but it's nothing special. The rest of the second week is a story of small, weak swells. The 26th of August morning offers some clean 4ft surf, but the energy is barely there (142). It's the kind of day for a longboard and a patient paddle.
For the rest of the run, we see some glassy mornings – like the 28th of August – but the swell is under 3ft and the energy is weak. It’s lacklustre. If you're a beginner, the 7ft on the 20th might be a bit much, so wait for cleaner, smaller days after that. But for the experienced crew, that Thursday morning is your only real window for anything with a bit of punch.
Alright, stay patient, keep an eye on the charts, and I'll see you in the water.
