The statewide average temperature in July was 74.4 degrees, 0.9 degrees below average. That is not nearly as cool as the record-setting July 2014 when the average temperature was only 70.3 degrees (5.0 degrees below average). On the other extreme, July 2012 was 81.8 degrees (6.5 degrees above average).

The statewide precipitation for July in Illinois was 5.22 inches, 1.17 inches above average. However, that precipitation was not evenly distributed. Areas around Quincy, Kankakee, Bloomington, and south of Carbondale all received amounts in excess of 8 to 12 inches. The largest monthly totals so far include Winchester with 14.40 inches, White Hall with 12.63 inches, and Sheldon with 12.16 inches.

Meanwhile, there were a few dry spots, including the northwest corner of the state and a large swath on either side of Interstate 57 between Champaign and Marion.


The Illinois State Water Survey at the University of Illinois at Urbana-Champaign, a division of the Prairie Research Institute, is the primary agency in Illinois concerned with water and atmospheric resources.
