Has the weather in California really been wetter than normal this fall? Maybe wetter than the last couple of years, but I think no worse than average for the last 20 years.
And the rain we've had this month is very light by East Coast standards; maybe one or two rain showers per week, no more than half an inch total per week along the coast. Most of the rain has been north of San Francisco so far this year. Southward, the weather has been warmer and drier.
If you're staying in hotels at night, you can always stay an extra night if the weather gets really bad.
