Chicago’s dry summer of 1988

Dear Tom,
I remember a period of drought in Chicago during the summer of 1988, ending on the day of the Cubs’ first night game on Aug. 8. Is my memory serving me correctly?

Dear Beth,
It is, but drought conditions did not end on Aug. 8. They persisted into autumn. Precipitation data from Midway Airport shows that from Jan. 1 through Aug. 8, 16.7 inches of precipitation fell, the 10th-driest at that station in the period from 1929 through 2017. However, it was the fourth-driest from Jan. 1 through Sept. 30, with 19.58 inches. The driest was 1934 with 15.52 inches.
Far above-normal temperatures also accompanied the 1988 drought. The period May 1 through Sept. 30 was the warmest ever at Midway Airport with 72.9 degrees (versus the normal of 69.3).
