The Lowdown
Alright, let’s break down what’s coming up for the next couple of weeks here.
Alright, surfers, Rusty here. We’ve got a mixed bag ahead at La Boca Con Con. The water’s sitting at 58°F, which is a touch warmer than normal for this time of year. The first real action worth paddling out for isn’t until Monday the 11th, with a small but workable swell.
The whole picture starts off pretty average. The early part of the week is a bit of a grind, with small, weak swells and mostly cross or onshore winds making things looked chopped. You’ll be scratching around for scraps. There’s a gap of a few days where the surf isn’t really worth a mention.
We start to see some life on Tuesday morning, August 12th, but the swell is tiny at 1ft from the WSW, with a very long period of 19 seconds. That’s all groundswell energy, but it’s just not enough size to do much at a beach break; it’ll break too straight. The wind is light cross, so it’s clean, but you’re basically waiting for a barely-rideable bump.
The real standout in this entire 16-day window is shaping up for Wednesday, August 20th. This is the one you want to circle. We’ve got a solid 6ft swell rolling in from the SW, with a period of 14 seconds – that’s proper groundswell. The energy is pumping, and the wind is forecast to be glassy, dead calm. This is going to be clean, powerful, and lined up. It’s a bit on the bigger side, so it’s more for the experienced crew. The morning session is the pick of the whole run.
The Thursday and Friday after that continue to offer decent, clean surf with consistent SW swells and offshore wind, but they won’t quite match that Wednesday peak. Saturday the 23rd sees a return of lumpy onshore wind, and the final few days of the period look messy with poor conditions.
So, to wrap it up: the first week is a slow, frustrating wait. The clear winner is the morning of Wednesday, August 20th. Get on it.
Rusty.
