PHOENIX — Phoenix’s streak of daily heat records reached 15 consecutive days after a 37-year-old mark was beaten on Tuesday.
The mercury at Phoenix Sky Harbor International Airport, which the National Weather Service (NWS) uses for the city’s official records, hit 105 degrees at 11:55 a.m. The previous record was 104 degrees, set in 1987.
Phoenix has broken daily heat records 13 times and tied two more since the streak began on Sept. 24.
How much longer will Phoenix see daily heat records?
Daily record highs likely won’t stop any time soon. Those in the Valley shouldn’t expect the long string of 110-degree days they saw during summer, but it’s still an unusually hot fall. Thus, the daily highs are getting lower due to the fact that fall has begun — but heat records are still breaking due to the rarity of this autumnal heat wave.
The latest forecast calls for highs that match or break the heat record each day through at least Monday.
Before this streak, Phoenix had never had more than seven straight days of record heat. Phoenix also had never reached 110 degrees after Sept. 19 in any year but has now done so four of the first seven days of October in 2024.
Arizona’s capital city has hit 110 degrees on 70 days in 2024, smashing past the previous record of 53 days set in 2020.
In addition, the Valley is in the midst of an excessive heat warning that’s been extended multiple times and is now set to end at 8 p.m. Tuesday, which would be its 14th day. The longest excessive heat warning during the record hot summer of 2024 was 10 days.
The public is advised to avoid spending time and working outdoors during the hottest parts of the day when an excessive heat warning is active.
Per city of Phoenix policy, the Echo Canyon and Cholla trails at Camelback Mountain and all Piestewa Peak trails are closed from 9 a.m. to 5 a.m. on days with excessive heat warning.
