The past month was the hottest September in Phoenix history.

The average temperature for the month of September was over 94 degrees, according to the National Weather Service. That’s more than 5 degrees above normal. It breaks a record going all the way back to 2001.

The scorching September temperatures came after the hottest summer ever in Phoenix. There have been a record number of days over the past few months with highs at or above 110 degrees. As of Sunday, 66 days in 2024 have passed the 110 mark. Phoenix typically gets just 21 days per year that hot.

Even more 110-degree days could be on the way. An excessive heat warning remains in effect through Friday in the Phoenix area.

Phoenix has never recorded temperatures this hot so late in a year before.
