I grew up in Southern California with sunshiney skies pretty much 365 days a year.
Now I live in New York with 6+ months of cold weather, a short spring and fall, and a humid hot 3 months of summer.
I do prefer the seasons, but I just wish fall and spring were longer! In my ideal world, winter = 2 months, spring = 5 months, summer = 1 month (can't stand the humidity), fall = 4 months. Alas no such thing exists.
Overall I have to say that California's weather can't be beat, but in New York you truly appreciate a beautiful day and don't waste it.
What is your ideal year round weather?
