The Lowdown
Alright, this is Rusty. Let's talk about what we're seeing for the upcoming stretch.
First off, the honest truth is, this is a tough period for us. The swell is just not cooperating. We’re looking at a long, frustrating gap where the waves are tiny and the conditions are pretty grim. From Tuesday the 18th of August all the way through the end of the month, there’s nothing worth paddling out for. We’re talking days and days of flat, weak, messy surf. The water temp is a touch warmer than normal for the time of year at around 77°, but that’s about the only thing going for us.
The first real chance, and I mean a chance, comes right at the end of the month. On Monday the 31st of August, we start to see some life. The morning has a clean offshore wind from the WNW, with a 4 ft east swell. The combined energy is moderate at best (112). It’s still pretty ordinary, but it’s the first time it’s not a complete write-off. Don’t get your hopes up.
Then, on Tuesday the 1st of September, things get interesting. The morning session at 12th Street Jetty (beach/jetty) is looking like the standout of the entire forecast. We get a glassy, dead-calm 5 ft east swell with a period of 8 seconds. That combined energy jumps to a moderate 332. The wind is glass, the conditions are good, and it’s actually surfable. The swell is right in that sweet spot for an advanced break like this. Keep in mind, this break sees crowds often, so expect company if you’re out there. It’s the only real highlight in the whole two weeks.
After that brief burst, things fade again. By the 2nd of September, it’s back to messy cross-shore winds and dropping swell.
So there you have it. A lot of waiting for one Tuesday morning that looks promising.
Rusty.
