Residents of Tucson and the surrounding area enjoy year-round
sunshine and low humidity which makes the summer heat (average maximum
temperature in July is 98.5 degrees) more comfortable than other
southern climates. Also, the temperature drops with the setting
sun, so evenings are quite comfortable. Known as the land of extremes,
Tucsonans are delighted about the swings which can span 40 degrees
from day to nighttime.
