Usually, my July visits to my family in San Francisco allow me to get away from Chicago's oppressive heat. This year, both cities are about the same, San Francisco just a little warmer than usual, and Chicago...well, it's the coolest July of my life:
July has slipped to the coolest to date here in 42 years—its 68.7°F degree average temperature running nearly 5 degrees behind the long-term (138-year) average. Friday's 70°F high was the first time in 53 years a July 17 temperature failed to rise above 70—you'd have to travel back to a 64°F high 85 years ago to find a July 17 that was cooler.
The average high for July's first 17 days has been 77.5°F—the second coolest in the 50 years of O'Hare Airport weather records dating back to 1959. Only 1967's 76.2°F tally has been cooler.
Maybe Chicago will have a super-hot August this year. Like, when I'm in London....
