places I've stayed a night in this past year climate battle

Chico, has the right balance of warm and cool weather for me and isn't too dry.

Eugene

Leavenworth then Eugene.

to be fair all these climates have a med pattern. you must like your summers nice and toasty though because Chico's summers are pretty darn hot, but luckily the city has plenty of trees for shade, including some massive valley oaks in lower Bidwell Park (super big park running through the city).

Chico

As a heat wanker, Chico wins this one in a landslide.

Yeah Chico

Leavenworth's winters do appeal to me with all that snow and decent cold, however, the rest of the year is too chilly. It has too chilly lows in general (aside from the winter months).
But by far the most important season to me is summer, and it needs to be hot, and Chico has the hottest (best) summers of the bunch.
Chico's winters aren't as interesting to me as Leavenworth's are, but I can tolerate those mild winters if the climate has hot summers.
