The coastal Pacific Northwest where most people live has mild weather all year, better than many parts of California. It rarely freezes in winter and rarely gets hot enough that you need an air conditioner in summer. Contrary to reputation, it has relatively few days of meaningful precipitation, especially in cities like Seattle that sit in a rain shadow.

If you are going to live unsheltered in the US, the cities in the PNW are definitely among the better locales to do so in terms of amenable weather.
