We enjoy 4 seasons here. If you can't handle that, you are right in not moving here. I doubt we have 300 days of sun, but I know we are not 50% cloudy, unless you find those nice puffy white clouds on bright blue skies a problem too? The biggest complaint I heard from friends that came to visit from Alabama during a BEAUTIFUL New England weather streak was that it was too dry for them. They were going through tubes of chapstick, no joke. Then again, to me ... Alabama is like living in a steam bath.
Here's a link for weather, it's on a "visit NH" site... ...

We are definitely not as cloudy as Seattle....
