On Tuesday, Phoenix finally snapped a record streak of 113 consecutive days of temperatures at or above 100 degrees — around 3.5 straight months. The previous record of 76 consecutive days was set in 1993, according to the weather service.
In total, the city has endured 120 days at or above 100 degrees so far this year, inching closer to the record of 145 total days set in 2020.
Phoenix also set a record this year for the total number of days at or above 110 degrees, with 61 so far. The previous record of 55 days was set in 2023.
Last year, Phoenix sweltered through a record 31 straight days at or above 110 degrees, obliterating the previous record of 18 consecutive days set in 1974.
Over the last week, cooler weather has finally brought some relief to Arizona’s capital city. Phoenix last recorded a temperature at or above 110 degrees on Sept. 10. But the cooldown may be short-lived, as weather forecasts show that the city may see temperatures in the triple digits again next week.
Overall, the months of extreme temperatures are part of a worrying trend for the desert metropolis, which already has a reputation for unrelenting heat. Climate change is increasing the frequency, duration and intensity of heat waves, and Phoenix’s hottest five summers in recorded history have all been in the past 11 years, according to the National Weather Service.
The conditions have been deadly. Maricopa County, where Phoenix is located, has confirmed 256 heat-related deaths so far this year, with 393 more under investigation, according to county records. Last year, at least 645 people died from heat-related causes in Maricopa County, a 52% increase over the previous year.
