This intense heat, measured at Sky Harbor International Airport at 3:40 p.m., shattered the previous daily record of 112°F from 2012 and 1905.
Even overnight temperatures were extreme, with a low of only 94°F, surpassing the prior record of 91°F set in 2023.
The relentless heat is cementing this summer as one of Phoenix’s hottest, with 21 days already reaching at least 110°F.
