The highest temperature record in Greater Phoenix in the past 10 years: 118 degrees Fahrenheit. About 4,000 homes were without power and air conditioners stopped working. It was a day like this. Last Saturday, the temperature in the greater Phoenix area soared to 118 degrees, becoming the hottest day in the United States and breaking the highest record in the past 10 years. The National Weather Service said active monsoon clouds could bring ground temperatures to 120 degrees, but they said 118 was still the city's hottest day yet. High winds from a summer storm toppled power lines, leaving thousands of suburban Phoenix homes without power. Maricopa County Sheriff Joe Arpaio ordered thousands of ice packs to be shipped to outdoor jails for use by inmates.
