Phoenix, Arizona has recorded its first-ever 100°F temperature in April, reaching 101°F on April 8, shattering the previous April record of 98°F set in 2020 by a significant margin.

Heat Wave

The entire Desert Southwest is experiencing an unprecedented April heat wave, with Las Vegas hitting 98°F and Tucson reaching 99°F. Temperatures are running 15-20 degrees above normal for early April.

Concerns

Last summer, Phoenix recorded 31 consecutive days above 110°F and 645 heat-related deaths. Officials worry that earlier extreme heat extends the dangerous season significantly.
