Pulling this from my butt but I seem to remember reading an article talking about this and they claimed San Diego was near perfect climate for humans. Individual tastes may vary.
definitely San Diego for me! 
North Carolina or Virginia. Maybe Washington state.
Berkeley, California. It always has the best weather in the bay area, which is almost sunny and not too hot, not too cold.
California has a rainy season, from Nov - March. We get rain from storms moving west to east via the jet stream; when something forms in the Pacific, it hits the states and moves on through. Lengths of storm and gaps between storms vary depending on El Nino, etc.
Severity diminishes as you go north to south. Some storms will hit northern California and miss Southern California, so they have generally better weather than we do; but the pattern is still the same.
And then, March - Nov, it does not rain. Never. (Well, hardly ever.)
Chicago! Yesterday it was sunny and 65, today it’s snowing!
What can I say? I like variety.
