I agree that predicting SFO wind is not the end of the story, but I
think we have a pretty good feel for the correlation between SFO and
SoSF readings and the wind we find at Coyote and 3rd.
I have thought about collecting data from sailors. I think we would
want the sail size used, sail size desired and sailor's weight as a
minimum entry; we could get fancier such as doing it hour by hour. I
even have my own daily logs going back to '91. But I think this is
premature until we can come up with a better prediction of the winds at
sites with plenty of objective history such as SFO (or, since web access
started a year ago, the CotW sites).
