That sounds kind of like Italy. Maybe not as much sunshine as California here up north, but it's certainly better than the UK or Belgium from that point of view.
Of course, the economy is in the tank, but maybe you can work remotely or something.
Going to the US is not easy: you'll have to find a company willing to hire you.
That said, if it's what you want, don't let the naysayers get in your way - go on a vacation there, travel around some, meet people, see what day to day life is like, and then go for it! It's not perfect, but there's a lot of good stuff there - much more than some of the haters here give it credit for.
Some people work crazy hours, many people don't. As someone who is likely to have a good job, you'll have decent health care, even if the system is a bit screwy.
Edit: a few other places to check out might be:
* Colorado (Boulder, Denver, Ft. Collins). Snowy, but still quite a bit of sun. If I ever went back to the US, this is high on my list of places to check out.
* Austin, Texas. I don't know much about it, but it's supposed to be a nice place, and definitely sunny/hot.
* Bend or Ashland in Oregon. Not as sunny as California, and cold in the winters. Not as many jobs either, but nice smallish towns.
