The Lowdown
Alright, Rusty here again. Let's break this down in feet and miles per hour, because that's how we surf.
Honestly, for the next stretch, the surf is almost non-existent. We're looking at a bone-dry run for over a week, with swell energy barely registering. The wind is all over the place, mostly onshore or cross-shore, leaving the water lumpy and chopped up. This is a beach and jetty spot, and with how it's looking, it's a kiteboarder's playground way more than a surfer's.
We finally get a pulse on Friday, August 28th. The morning session cleans right up with light, glassy conditions. The swell is only about 2 feet from the South, but the clean, windless surface makes it the first surfable moment in a long time. The energy is still weak, but it's a window.
The real standout, if you've got the patience, is Tuesday, September 1st. That morning, the wind turns glassy again out of the WNW. The swell holds at about 1 feet from the ESE, but it has a longer period of 11 seconds – a bit of groundswell that will give the waves a bit of shape. The energy bumps up a notch, and with the entire morning being glassy, it's going to be as clean as it gets. The swell is tiny, so it's for the small-wave gear, but it's the only real window we have.
So, there's a long, slow grind to get there. Friday the 28th is a quick, clean moment. But the one to wait for is Tuesday, September 1st. Clean, glassy, and a hint of groundswell. That's your day. After that, it's right back into the wind and chop.
Rusty.
