The Lowdown
Alright, Rusty here. Let's break down what's happenin' at 120th Street.
We're in for a slow start – the first week and a half is mostly tiny, weak surf with swell heights barely hittin' a couple of feet. The combined energy is weak, mostly under 100. The wind's been messin' things up too, makin' for choppy or blown-out conditions. Not much to get the heart racin'.
Things look a little better around Thursday the 17th. A south-east groundswell comes in around 2.3ft on the morning, with a period around 9 seconds. The combined energy bumps up to a moderate 88, and with a light, clean offshore breeze from the southwest, it'll be the most ridable window we've seen. Still, it's small and just ordinary.
Then Friday the 18th morning is similar – 2ft of south-east swell, energy at 60, and a clean cross-offshore from the west-northwest. It's surfable, but we're really strugllin' to find any quality here.
Honestly, there's no standout day in this whole 16-day stretch. The biggest pulse we see is barely 2.6ft. If you're jonesin' for a paddle, the cleanest conditions will be Thursday 17th morning and Friday 18th morning when the wind's favorable. But don't get your hopes up.
