Jason -
The whole point of having the tournament at this time of year is to attract tourist business to the Monterey Peninsula during the off-tourist season. If they could push the tournament back a few weeks and make it the last stop on the West Coast swing, that might increase the odds of marginally better weather. Other than that, the Monterey Peninsula area has all the tourist business it can handle thru the spring, summer and fall.
Remember Pebble Beach basically forced out the Cal State Amateur a couple of years ago, after that tournament had been held there in June for about 80 years.
