On the evening of July 13, 1977, a massive power failure hit the city. With temperatures in the mid-nineties Fahrenheit and the humidity high, New Yorkers sweltered. By the time power was restored at 10:39 p.m. the next night, the city had been without power for 25 hours. Beame set up a Blackout Action Center at the New York City Police Department headquarters. The blackout resulted in raw sewage washing up on beaches and spoiled food in hundreds or thousands of restaurants around the city.
