Having lived in San Diego and Pocatello, I'm definitely better suited to a cold climate. As long as I'm wearing a medium long sleeve shirt, I'm good down to around +34 without a jacket. I can tolerate riding my motorcycle around in +26F as long as the streets have no ice patches. The summer weather here is bone dry. I handle that just fine. Add a little humidity and I'm soaked to the skin with perspiration.
Time to pack up the skis and snowshoes and move back home.
