Cooler-than-normal high temperatures produce the “Sweatless Summer” of ‘96

It’s way cool. Cities throughout the Northeast have enjoyed one of the coolest Julys on record, according to the Northeast Regional Climate Center at Cornell University. New York City never saw an official high temperature in July above 89 degrees at Central Park – for the entire month – the first time that has happened in 107 years.

At 1.9 degrees below the average temperature for the month, the 12-state Northeast region enjoyed its 10th coolest July in 102 years of record keeping, according to climatologists at the center. You might say, it’s the “Sweatless Summer” of ‘96. The coolest July was in 1962.

“Average temperatures were below normal by 1. 9 degrees,” said Keith Eggleston, climatologist at the Northeast Regional Climate Center.“That’s a more significant drop than I thought.” He explained that the average high temperatures throughout the month have not been as high as normal. However, low temperatures through the month have been very close to normal.

Other Northeastern cities joined New York with below-average high temperatures. Philadelphia never saw temperatures above 89 degrees in July, which last happened in 1906. It’s been 34 years since Charleston, W. Va., went an entire July without reaching above 89 degrees, and Williamsport, Pa., has gone two decades since it encountered a July without hitting 90 degrees.

Even traditionally sultry, sweltering and stifling places like Washington, Baltimore and Richmond, Va., fared well. In fact, Washington National Airport at Arlington, Va., registered the Northeast’s highest temperature for the month at 94 degrees.  Richmond, Va., and Wilmington, Del., both at 93 degrees, registered the second highest temperature for the month. Baltimore’s hottest day in July was a mere 92 degrees, while Washington Dulles Airport failed to record a temperature above 90 degrees.

Maryland and Vermont saw departures from average temperatures at negative 2.3 degrees, the biggest departures in the Northeast.  Pennsylvania’s July ranked as the fifth coolest on record; the coolest July there was noted in 1976. In 1992, Vermont and New York enjoyed their coolest July ever.

This year New York had its 11th coolest, while Vermont enjoyed its 14th coolest on record.

“We had a complete lack of extreme temperatures,” Eggleston said. Climatologically speaking, he explained, there is nothing to worry about: This cooling period is just a weather pattern the Northeast can enjoy right now. “We never really had any kind of a heatwave in July that would have pulled that average high temperature up.”
