AZ is most desirable in Febuary & March. Temperatures are in the 70's in the southern part of the state, 50's in the middle of the state and still snow capped mountains in the northern tier. The Phoenix/ Scottsdale are is busy with winter league baseball games, NASCAR racing, golf, sightseeing and of course shopping. Days are in the low to mid 70's evenings lowes are in the 40's. Remember desert locations cool down at night but warm very quickly by mid morning. The snowbirds flock to the valley for respite from the snowy cold northern tier of our country. We do not have the hiumidity of Florida's winter baseball leagues do.
