A Preview - Life In Phoenix; Pouring Concrete At 1:00 AM; Hiking After Dark, Jogging Before Sunrise
EDIT
For workers doing concrete pours, jobs can start close to midnight so the material doesnt get too hot or dry too quickly and later crack. At 1:30 a.m., on a construction site near Peoria, a Haydon Building Corporation crew listened for the approach of mixer trucks along a dusty dirt road marked with green flares. Moths and grasshoppers dashed against the stadium lights. The crew was working on a bridge, hooking future housing developments to the suburban road matrix.
Night jobs are not easy on the workers, said Katie Perry, a director at Haydon. You are getting up and awake in the middle of the night, and you have to be highly alert. But such shifts mean they avoid the worst of the heat on those arduous jobs.

Last year, heat caused or contributed to the deaths of 182 people in Maricopa County, which includes Phoenix. Preliminary figures suggest the toll this year will be similar, if not higher, according to the health department. Thirty-six percent of those who died in 2018 were 65 or older and at least 23 percent were homeless. Recent research found that mobile home residents are also especially vulnerable. In 2012 and 2014, nearly half the indoor heat deaths occurred in mobile homes, said Patricia Solís, a geographer at Arizona State University.

In nearby Tempe Beach Park, runners, bikers, walkers and a paddleboarder exercised in the 94 degrees of first light. I can quantify it, said Glenn A. Dotson, who arrived at 5 a.m. to do a solo run before joining the local chapter of Black Men Run for a longer one. It is a three-hour shift earlier. By 6 a.m., the group had stretched and started along the Salt River. We dont go anywhere without our water, said Jarred Ervin. There are water fountains all along the route, he said. We have them pretty much memorized and all mapped out.
