Marine layer deepens, SW flow increases and Sherman Island sees AM winds. by Mike Godsey, mike at iwindsurf.com In this video animation from the GFS model the imagery switches back and forth from the weak surface winds to the powerful 500mb wind of an upper trough at ≈ 18,000 ft. Looking at the weaker surface…
Meet the nemesis of Coyote and 3rd. Ave. winds. by Mike Godsey This blog is a work in progress but it is so relevant today that I thought I would at least post the graphics. Sometimes you read in the forecast that the pressure gradient is strongest to Redding. And you probably wonder how an areas…
Forecasters cringe. by Mike Godsey As you read my forecast for 7 AM this morning you are also probably cringing both at its length and all the weasel words. Well here is my excuse: Different models have different resolution, different parameters and approach the physics of the atmosphere from different perspectives. So when it comes to…
Combo of massive NPH and unusual venting thermal low in Basin promise strong wind! by Mike Godsey Most models and forecasts promise strong wind this Friday and through the weekend.

Why good forecasts… go bad by Mike Godsey “I hate it when F**king Godsey promises on Friday night that Saturday morning will see low 20’s at Sherman Island .

Weird wind pattern for the Bay Area. by Mike Godsey, mike@iwindsurf.com So I am gearing up for resuming Bay Area forecasting last night by looking at all the models. And looking at the WRAMS I see something impossible. I went to sleep assuming that is was just a bug in the model output and the forecast would return to reality by…
Here is how we coax NW wind into the Bay. by Mike Godsey, It was a day much like today wind wise. There I was 22 years old slowly slogging out the Golden Gate Hawaii bound on a sloop only 2 feet longer than my age. I was totally ignorant about the North Pacific High’s surface NW…
