Yes

    Then for about 10 years we had fewer troughs and the the North
    Bay had crummy wind. Now we may be swinging into another
    pattern. There seems to be poorly understood climatological
    cycle going on."

I remember reading Mike's old book on WSing in the Bay Area and it
spoke of a Bay Sailor could find wind 10 of 11 days but had to
travel...

I think it has to do with the SunSpot cycle which peaked in 2000
after a trough in 1996/97 http://www.sunspotcycle.com/

I think our best wind at Coyote since I have been windsurfing was in
1995/1996... near the trough of this chart
http://science.msfc.nasa.gov/ssl/pad/solar/IMAGES/ssn_recent2.gif

The good news is we are not approaching the next trough.
