As July winds down, the brutal heat responsible for a swarm of record high temperatures across the Pacific Northwest and triple-digit readings in many sections of the West and Southwest is showing no sign of making a move on Chicago. Temperatures here will remain comfortable, with readings near or a bit below typical mid- and late-summer levels. While July’s average temperature in Chicago ranks 3rd coolest of the past 81 years–running nearly 4-degrees below normal–Rockford and South Bend and Ft. Wayne, Ind., are all on track to close the books on the coolest July on record. The breadth of the month’s cooler-than-normal weather has been, and continues to be, remarkable, literally covering the entire Midwest. Some weather observation stations are reporting July temperature deficits approaching 8 degrees.
Wednesday’s 81-degree high in Chicago marked only the 34th time this year the temperature has reached 80 degrees. Records reveal a typical year has logged 49 such days by now–44 percent more than this year’s tally.
Dear Mr. Skilling,
I recall a rather cool and cloudy summer, like we are experiencing now, in 2001 or 2002. Can you confirm my recollection?
Mark J. Girolamo, Aurora
Memories can be deceiving. It’s certainly true that this summer has been cool. As of July 26 (when you wrote to us), it was running 2.7 degrees below normal and it ranked 5th coolest out of 50 years of temperature data at O’Hare Airport. On average, 10 of the annual tally of O’Hare’s 17 days at or above 90 degrees should already have occurred, but we had logged only three.
However, the summer of 2002 (through July 26) was hot: 2.6 degrees above normal, 7th hottest, 16 days in the 90s. In 2001, summer ran near normal: 0.4 degrees below normal, 28th warmest, 10 days in the 90s.
Might 2000 have been the cool summer that you recall? With an average temperature of 68.9 degrees and no 90-degree days, it ranked 9th coolest.
