The sun shines through clouds over Phoenix on Sept. 17, 2026.

This summer was the hottest on record across the contiguous U.S — and it was very hot in Phoenix.

This summer’s temperatures across Arizona were 2.7 degrees hotter than normal, the analysis shows. It was the hottest summer on record statewide and the second-hottest on record for Phoenix.

Here's a look at the temperatures recorded at Phoenix Sky Harbor Airport from June 1 through Aug. 31.
