The Lowdown
Alright folks, let's be real about this forecast. Honestly, it's pretty grim out there for the next couple of weeks. This is one of those stretches where you might be better off tuning the boards or getting the kites out, because the surf is going to be tiny, weak, and mostly junky.
Right now, and through the weekend, it's a sea of onshore slop and flatness. Friday the 31st has a dribble of 2 feet of messy, cross-onshore junk with a weak period. The energy is a feeble 7, which tells you all you need to know. The water is about average for the time of year at 62°F. Saturday and Sunday are looking clean and glassy in spots, which is just a cruel tease because the swell is basically non-existent.
We're in for a several-day gap where there is simply no surf on offer. The waves just disappear. We roll into next week and the story remains the same: tiny, short-period waves with a lot of chop. We see the biggest swell of the whole stretch on Tuesday the 4th, a whole 2 feet, but it's riddled with onshore winds and turns into a bumpy mess.
It's not until the second week, around Friday the 7th of August, that we see a long-period groundswell, but it's tiny. That 12-second period would be great, but there's nothing behind it. It's a total tease.
The one bright spot, and I mean the only one, looks like Sunday the 9th of August. The wind is forecast to go completely glassy in the afternoon, and there's a little 1 foot SW swell at 8 seconds. It's not going to be a world-class session, but it might just be a clean, fun little longboard wave when no one else is out. That's your best bet, and it's not a great one.
The rest of the window gets messy again, with more wind and weak energy. This is a bad run for the area, but it won't last forever. Forecasts can change, so don't throw in the towel just yet. Keep your expectations low and look for those windows of clean but small surf.
