Best weather in continental USA? You mean in Orange County? I lived in Irvine for 6 years and it was essentially an average of 72 all year and mostly sunny days and barely any rain at all. Versus SF which gets way more cloudy and rainy days and isn't as warm.
So that would be, cold and foggy to cold and foggy? San Francisco weather is not usually touted as "good" by most common measures. I'll grant you that it is consistent, but most people appreciate seeing the sun now and then.
I've left now but I miss the SoCal weather badly.
