Sunday was the hottest day observed in any year prior to the summer solstice, and the hottest day on record for so early in the season, in Yuma (120°F, ahead of June 24, 1957), Phoenix (118°F, ahead of June 24, 1929), and Tucson (115°F, ahead of June 25, 1994). Sunday also tied as Phoenix’s 5th hottest day on record, and Yuma’s 5th hottest. In Tucson, only two other days have been officially hotter than Sunday: June 26, 1990 (117°F) and June 29, 1994 (116°F)
