The first official weekend of summer brought a scorching heat wave to the Northeast and Midwest, with temperatures climbing well into the 90s.
Boston reached a high of 95 degrees Saturday -- the hottest the city has been since August 18, 2002 -- and cracked the 90-degree mark again on Sunday. In response, city officials extended hours at some neighborhood pools to allow kids to keep cool.
"As long as you're in the shade it's OK," said Sean Cantwell, 28, of Cambridge, as he left a store in Harvard Square with a cold drink. "When you're out in the open, it's pretty rough."
By Sunday, the Dickson Bros. hardware store in Harvard Square had nearly sold out of a truckload of air conditioners it received on Friday.
"The fans are going fast, too," said Dennis Brennan, the store's manager.
In Michigan, temperatures on Sunday hit 94 in Battle Creek, 93 in Kalamazoo and 91 in Jackson. It's the seventh-hottest June on record in the state, with an average temperature of 72.4 degrees -- about 4 degrees above normal, the National Weather Service said.
"Even our dog thinks it's hot," said Marcus Wright, 9, of Farmington Hills, as he and his sister sought relief by running through a sprinkler.
