The only similarities here IMO are that neither get exceedingly cold. Otherwise, I'd say the weather is vastly different in FL than CA, at least for half the year. FL is much more humid and the summer as I'm sure you know are brutal whereas coastal CA stays pretty pleasant most of the year with the exception of the brief periods of Santa Ana winds which heat things up.

Not saying you're wrong about FL in any other regard, but for a Californian, they would likely find the summer here pretty unbearable.
