Phoenix scorches at 110 for 19th straight day, breaking big U.S. city records in global heat wave
PHOENIX — A dangerous 19th straight day of scorching heat in Phoenix set a record for U.S. cities Tuesday, confined many residents to air-conditioned safety and turned the usually vibrant metropolis into a ghost town.
The city’s record streak of 110 degrees Fahrenheit (43 Celsius) or more stood out even amid sweltering temperatures across the globe. It reached 117 degrees (47.2 Celsius) by 3 p.m.

Human-caused climate change and a newly formed El Nino are combining to shatter heat records worldwide, scientists say.
No other major city – defined as the 25 most populous in the United States – has had any stretch of 110-degree days or 90-degree nights longer than Phoenix, said weather historian Christopher Burt of the Weather Company.
“When you have several million people subjected to that sort of thermal abuse, there are impacts,” said NOAA Climate Analysis Group Director Russell Vose, who chairs a committee on national records.
For Phoenix, it’s not only the brutal daytime highs that are deadly. The lack of a nighttime cooldown can rob people without access to air conditioning of the break their bodies need to function properly.
With Tuesday’s low of 94, the city has had nine straight days of temperatures that didn’t go below 90 at night, breaking another record there, according to National Weather Service meteorologist Matt Salerno, who called it “pretty miserable when you don’t have any recovery overnight.”
On Monday, the city also set a record for the hottest overnight low temperature: 95 (35 Celsius). During the day, the heat built up so early that the city hit the 110 mark a couple minutes before noon.
Dog parks emptied out by the mid morning and evening concerts and other outdoor events were cancelled to protect performers and attendees. The city’s Desert Botanical Garden, a vast outdoor collection of cactus and other desert plants, over the weekend began shutting down at 2 p.m. before the hottest part of the day.
In the hours before the new record was set, rivers of sweat streamed down the sunburned face of Lori Miccichi, 38, as she pushed a shopping cart filled with her belongings through downtown Phoenix, looking for a place to get out of the heat.
“I’ve been out here a long time and homeless for about three years,” said Miccichi. “When it’s like this, you just have to get into the shade. This last week has been the hottest I ever remember.”
Some 200 cooling and hydration centers have been set up across the metro area, but most shut down between 4 p.m. and 7 p.m. due to staffing and funding issues.
