With just two weeks of summer left, oppressive heat will continue to broil the low-lying deserts of California and Arizona over the next few days. Phoenix, in particular, is expected to set a few ominous records with temperatures over 110 degrees Fahrenheit this weekend.
“A period of very hot temperatures, even by local standards, will occur,” reads an urgent excessive heat warning issued by the National Weather Service Thursday morning.
Temperatures in the sprawling Phoenix metroplex are forecast to push the mercury as high as 114 degrees on Saturday and Sunday. The city has already seen 52 days with highs over 110 degrees in 2023; adding two more to that count would pass the previous record of 53 days over 110 degrees set in 2020.
Earlier this summer, the city endured a 31-day streak of days over 110, shattering the previous record of 18 days.
Maricopa County, which includes Phoenix, is also on pace to reach a more grim milestone — a record for annual heat-associated deaths. As of Wednesday the county counted 194 such fatalities in 2023 so far, with 351 more deaths under investigation to determine a link to the heat. At this point in 2022, there had been 153 confirmed deaths from the heat with 238 more still being investigated. Last year’s final tally of 425 heat-associated deaths is the most recorded in a calendar year since the county started keeping track in 2006.
More than half of the heat deaths so far in 2023 are among people who are either experiencing homelessness (44%) or have an unknown living situation (10%).
The City of Phoenix Parks and Recreation Department closes popular hiking trails from 9 a.m. to 5 p.m. on days when the National Weather Service issues an excessive heat warning. Anyone wanting to take a walk at the city’s iconic Camelback Mountain will have to hit it early or later in the evening this weekend.
