The Lowdown
Alright, let’s have a look at what the next couple of weeks are serving up.
Honestly, it’s looking pretty grim for Barvas. We’ve got a massive dry spell with next to nothing rideable for days on end. The first real chance of a paddle is a very fleeting window on Monday afternoon the 11th, but it’s small.
Let’s break it down. The main standout, and sadly the only highlight in this whole 16-day run, is on Tuesday morning the 13th. The water temp is sitting at 57°, right where you’d expect for this time of year. You’ll get some chest-to-shoulder high surf, around 4ft to 5ft, pushing in from the WSW with a decent period. The wind is light and cross-off, which will keep things reasonably clean. The combined energy is moderate at 441, so there’s some push there. It’s a reef break, so it needs that direction to line up, but it could be fun for a bigger board. Crowds are rare, so you’ll likely have it pretty much to yourself.
Before that, nothing to write home about. From now until the 13th, the wind is all over the place, and the swell is either too small, too short period, or crossed up with onshores. Even though there’s a brief moment of glassy conditions on Monday afternoon, the swell is only 4ft from the north with a short period, making it super weak at 482 combined energy.
After that one decent window on the 13th, it’s back to the same story. A lot of poor to marginal conditions with onshore wind and messy chop. There’s a brief tease on the morning of Wednesday the 20th with a bigger 6ft swell, but the wind is straight onshore, so it’ll be a washing machine. Nothing to get excited about.
Then we hit a real dead zone from around the 24th onward. The swell completely drops out and the wind gets nasty, 25 mph cross-onshore. That’s not surfing, that’s a survival paddle.
So, in short, if you’re keen, the only realistic shot is a dawny on Tuesday the 13th at Barvas. Everything else is a hard pass. It’s a classic case of waiting for the next front to shift, but that’s just not happening in this window.
