The average temperature for June, July and August was 74.4 degrees, which ties the record high set in 1973, said Alan Dunham, a meteorologist with the Boston-area office of the National Weather Service.
Hartford already broke a record for days at 90 degrees or hotter. There were 39 such days this year at Bradley International Airport, which broke a record of 38 days set in 1983. There were 13 90-degree days in August, 20 in July and six in June, Dunham said.
There is no 90-degree weather in the forecast for upcoming days, including during Labor Day weekend, which looks pleasant so far.
