The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are shaping up like for Barvas.
Right off the bat, I gotta be straight with you – the next week or so is looking pretty grim. We’ve got a pulse of swell coming in on Saturday the 25th, but with a nasty 30 km/h onshore wind out of the west, it’s just going to be a mess. That 10ft swell is all blown out and ugly. Sunday and Monday aren't any better, with cross-onshore winds keeping things choppy and poor. You’re basically looking at a solid gap of useless surf for the first few days.
There is a tiny window of hope on the morning of Tuesday the 28th. The wind swings around to a light SSE cross-off, which will clean things up nicely. The swell drops right off to a mere 4ft from the north, but with a clean face and a moderate combined energy (514), it’ll be the only thing worth paddling out for. Don't expect much power, but it might be the most fun you'll have all week. After that, it’s back to the doldrums with small, weak, and windy conditions through the end of July and into the first week of August.
Now, here’s where it gets a little more interesting. Looking way out to Friday, the 7th of August, we get a decent shift. The morning shows a 3ft swell from the west, but the wind turns offshore from the ESE at 20 km/h. The combined energy is a moderate 206, and the period is a better 9 seconds. That is a proper groundswell window. The offshore wind will make it clean, and Barvas is a reef, so that longer period will wrap in nicely. This is the standout of the whole forecast. It’s a long way off, so don’t bank on it, but it’s the one to keep an eye on. The water temp is around 58° and pretty much normal for this time of year.
So, in short: one clean morning on the 28th for a tiny wave, and a promising, but distant, offshore session on the morning of the 7th of August. Everything else is a write-off.
Rusty.
