Hi Gang,

NE winds aloft plagued many Bay Area sites today and even Pismo had issues with this flow.

Check out this animated blog:

Cool. Really shows the micro climate around here. This not only helps understand the winds and windsurfing here, but helps me choose where I'm going to play golf...

Hi Novaan,

Glad the blog was helpful. What makes this situation especially difficult is that the NE wind coming down the Central Valley and over the mountains is warm air. So when it hits terrain it lifts and could go completely over Pismo allowing the ocean winds to hit the beach full strength. That is what happened at the location in the red diamonds.

As you can see in the model animation below 3rd. Ave. in the Bay Area very frequently had a similar situation near the launch and nearshore waters this year. Except for 3rd. the spoiling winds aloft were from the SW and often pushed the favorable WNW winds away from shore where they blow in the channel. Extremely frustrating for locals since we can barely forecast when this will happen.

So at this point in computer model technology we can tell when there will be spoiling winds aloft but not the exact location they will impact.

Kinda helps explain my bike ride this morning when I had a tailwind in Oceano and a headwind in Grover Beach and Pismo (heading north west).
At least cooler air came with the head-wind cuz it was warm and very dry.
