SSW wind through Muir Bay & Gate focuses San Pablo Bay robbing Sherman Island of peak winds.

Forecast note at 7AM today: “As the marine surge ramps up the flow will first be diverted into Napa in the so watch the San Pablo Bay sensor for S to SSW wind. If this happens Sherman will not pick up until the San Pablo Bay sensor turns SW.”

Well as I write this at 4PM the winds are still SSW at our San Pablo Bay sensor and Sherman Island is only seeing upper teens winds not the mid 20’s potential forecast.

The imagery at the bottom of the page shows how S to SSW winds at the San Pablo Bay sensor shunts the wind that should go to Sherman Island into Napa. If this happens Sherman will not pick up until the San Pablo Bay sensor turns SW.

Rest of the sites are in the forecast range or stronger with Crissy and Treasure Island more upper 20’s to 30 rather than the mid 20’s forecast. I suspect few are complaining except for those who went to Sherman Island for epic winds and did not read the Forecast note at 7AM.

Here are a bunch of images that tell the story.
