July’s torrid heat and torrential and frequent rains made the month one of the hottest and wettest Julys ever in Chicago.
And there was hardly any break from the heat, with temperatures reaching 80 degrees or higher 30 out of 31 days.
That made July Chicago’s third-hottest on record, according to the National Weather Service.
There’s only been one July when Chicago hit 80 degrees every day — in 1955, which was the city’s hottest July on record and part of the hottest summer, as well.
The lack of any cooling rain early in the month contributed to the heat, says forecaster Rose Sengenberger of the weather service.
That was remedied July 22 and 23. That’s when 8.2 inches of rain fell — including a record-setting 6.68 inches on July 23, the most ever for one calendar day.
For the month, we had a July-record 11.15 inches of rain, making it Chicago’s seventh-wettest month on record.
The rain was part of the weather pattern known as the Ring of Fire, where high pressures centered on the southern and eastern parts of the country contribute to high southern temperatures and thunderstorms — termed “fire” by meteorologists — around the edge of the ring, Sengenberger said.
