hottest recorded temperatures in tucson, arizona
Now back on that date of June 29th, 1913, Tucson was hot but not the hottest we have ever been. The hottest temperature for Tucson was 117Â° on June 26th, 1990. Phoenix on that date saw 117Â° while Douglas was much cooler. Monsoon moisture probably moved in and kept the southern corner of Arizona cooler with clouds as Douglas was only 106Â° (still hot).
