Hottest Phoenix July months on record: How 2025 stacks up so far

The last two summers, Phoenix residents have endured the two hottest months of July on record. But as the end of the month approaches in 2025, temperatures have been significantly cooler than residents have come to expect.

Instead of long stretches of temperatures well above 110 degrees, Phoenix weather has been closer to the “status quo,” said National Weather Service meteorologist Tom Frieders. “It’ll still be hot next week,” Frieders told Phoenix New Times. “But it’s not going to be comparable to the last two years that we saw those record levels.”

As of Wednesday, the average temperature this month is 97 degrees, well short of the triple-digit averages for July the last two years. However, as residents look toward August, temperatures are expected to “warm to back above normal by the time we get into this weekend and early next week,” Frieders said.

On Sunday and Monday, temperatures will rise to around 110 degrees. A monsoon is also expected early next week, causing temperatures to drop slightly, but Phoenix will still be in the 105-110-degree range, which is “pretty close to normal for this time of year,” Frieders said.

Hottest July months in Phoenix

So, this July isn’t expected to break any heat records. But how does it compare to previous years?

While NWS is “not projecting any kind of extreme heat or record heat” this July, Frieders said, this month is still likely to be among the hottest Julys on record.

1. July 2023 - 102.7 degrees
2. July 2024 - 101.1 degrees
3. July 2020 - 98.9 degrees
4. July 2009 - 98.3 degrees
5. July 2003 - 97.6 degrees
6. July 1989 - 97.4 degrees
7. July 2005 - 97.2 degrees
8. July 2016 - 97.1 degrees
Tie-9. July 2010 - 96.7 degrees
Tie-9. July 2019 - 96.7 degrees
Tie-9. July 2022 - 96.7 degrees

With an average of 97 degrees, July 2025 would currently come in ninth. However, with temperatures expected to rise toward the end of the month, it could make a play for sixth or fifth.
