The Lowdown
Alright, Rusty here. Let's break down the next couple of weeks.
To be straight with you, the first week and a half is pretty grim. Tiny swell and messy, choppy conditions are the name of the game. The water is running unusually warm, 24°, which is a big departure from normal, but that doesn't help the waves. We're looking at a lot of flat, poor surf.
The first real glimmer of hope is Thursday, August 14th. The morning brings a long-period groundswell from the SSW, with a 18-second period and a swell of 3ft. The combined energy reads 643 (moderate). The wind is offshore from the West at 9 mph, so it'll be glassy. It's still a marginal call, but it's the best we've got. 15th Street (beach and reef) is usually consistent, but with that long-period swell, it might break a bit too straight and fat for the beach break, so manage your expectations.
Saturday, August 15th is the other standout. The swell pushes to 3ft from the SSW, with a 16-second period, and the wind is light offshore from the West at 6 mph. The energy is strong (582). For a beginner-friendly spot, 3ft is a fun size, and that offshore wind will make for clean, peeling waves. The long period means fewer sets, but the ones that come will have some real grunt.
The rest of the window fades back into small, cross-onshore junk. The whole stretch from August 2nd through the 13th is a total loss with poor conditions and combined energy mostly under 250. 15th Street has crowds listed as "often," so if you're heading out that Thursday or Saturday, don't be surprised to see a few others nutting up for the same swell.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for 15th Street may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
