After a year living in NorCal I have to say that it is astounding more people don't travel to the Bay Area to sail. From the beggining of April to the end of September somewhere in the reigon the wind broke into the low 20's EVERY DAY! I sailed 27 days in July at the Delta alone, and that was all 5.0 or smaller.
I sailed almost every morning and afternoon like clock work, and consistant ocean conditions through early summer could remedy anyone sick of the groundhogs day bump and jump forecast.
Eqaully as impressive as the consistant wind are the sailors. The level of sailing in all catagories is higher than just about every else on the mainland except maybe the Gorge, but then again alot of the hot shot Gorge sailors are transplants from the bay area. The Freestylers here can all through down, so can the wave guys, and the Racers are actually really fast.
Geographically, we were at perfect striking distance for a variety road trips. San Carlos wasn't a bad drive, nor was the Oregon coast, and my all time favorite spot, the Gorge. Not to mention 4 major airports within and hour or so drive makes escaping to other windy destinations a breeze.
California sailing is no secret, yet the amount of tourists there is limited. I guess a big part of it was that none of the shops offered adequate rental gear, especially when compared to Hood River. Still, it's so easy to fly in, rent a car, and be guarenteed sailing that more people should be visiting as a windsurfing destination, or maybe the locals just prefer to keep it all to themselves. Eitherway, California Loves windsurfers, and I will miss it this winter when I'm in my drysuite chasing the wind around Long Island.
