Phoenix reaches 110 degrees for the first time in October

PHOENIX – On Tuesday, the calendar turned to October, and for the first time in history, Phoenix reached 110 degrees in the 10th month of the year.

At Phoenix Sky Harbor International Airport, which the National Weather Service uses for the city’s official readings, the mercury reached 110 degrees at 1:15 p.m

Less than an hour earlier, Phoenix hit 108 degrees, setting a daily heat record. The previous daily record of 107 degrees was set in 2020.

Will temperatures in Phoenix rise to 110 degrees more often in October?

Tuesday likely won’t be a heat anomaly in Phoenix this month.

The forecast calls for new record highs every day until at least Monday. During this stretch, temperatures will reach around 110 degrees, so it’s possible that Tuesday won’t be the only 110-degree day in October.

NWS meteorologist Sean Benedict recounted KTAR News 92.3 FM On Tuesday, he said a large ridge of high pressure was responsible for increased temperatures in the western United States. As a result, he added, the excessive heat warning currently in effect for the valley through Friday night could be extended into the weekend.

Additionally, Phoenix ended its hottest September with seven consecutive days that either met or broke the daily heat record.

The average temperature in September was 94.6 degrees, breaking the previous record of 92.2 degrees set in 2001. The average daily high temperature in September in Phoenix was 106.6 degrees and the average low temperature was 82.5 degrees.

The hottest September in Phoenix followed the hottest June, the second-warmest July and the third-warmest August. Additionally, the 2024 “meteorological summer” (June-August) was the hottest on record in the city.
