As a lifetime Californian (granted one who grew up in Sacramento where it regularly exceeds 100F in the summer), I concur. One of the most depressing things about considering moving from California is the weather in much of the rest of the country. Much of the northern part of the country gets extremely cold and snowy in the winter, which is something I don't want to deal with. Much of the southern part of the country has very humid summers, which I also don't want to deal with. I remember living near Tokyo for a short time as an intern and experiencing its summer; a 95F day there felt like 110F in Sacramento. Thankfully I loved just about every other aspect of living near Tokyo, but Tokyo's hot and humid summers wasn't one of them.

My favorite weather is the Mediterranean weather on California's coast, particularly the Central Coast. The favorable weather is one of the reasons why the area is so expensive. Barring that, I can cope with the warm Mediterranean climate of the Central Valley. Yes it gets hot in the summer, but it's a dry heat, and the winters are also dry, with snow being a once-per-generation occurrence, and the spring and fall are just as nice as on the coast. Barring that, I like the weather in the Pacific Northwest; yes it does rain a lot, but the summers are amazing. I also heard good things about the weather in parts of New Mexico, where it's a high elevation desert and thus it doesn't get too hot in the summer, and where it sometimes snows in the winter but doesn't get extremely cold like it does in places farther north.
