Earlier this summer, Phoenix spent nearly all of July with high temperatures at or above 110 degrees, smashing their record for consecutive 110-degree days at 31. When factoring both the high and low temperatures, the average temperature in July reached 102.74 – making Phoenix the first major city in the U.S. ever to average 100 degrees or more for a month.
"Even with extreme heat like we saw this summer, these deaths are preventable," Dr. Rebecca Sunenshine, medical director for MCDPH, said back on Oct. 19. "This tragic record reminds us that as a community, we have more work to do to prevent these deaths."
Overall, it was their hottest meteorological summer on record, with an average high temperature of 109.2 degrees, breaking the previous record of 108.5 degrees set in 2020.
"Maricopa County residents and visitors should continue to practice heat safety and check on neighbors, even this late in the season, because heat illness and deaths can occur all the way into November due to rising temperatures," Sunenshine added. "It’s not just extreme heat days that can turn into a tragedy."
