The triple-digit heat of Calexico, just north of the Mexico border in California’s Imperial County, can be deadly to those without shelter. The average July temperature there is 107 degrees, among the hottest in the U.S. This summer, temperatures on some days topped 118 degrees.
Elevating that deadly risk is the fact that the city’s lone cooling center, the public library, is open only five to six hours a day on weekdays.
