Based on preliminary data, July was both cooler and wetter than average for Illinois.
The statewide average temperature in July was 74.4 degrees, 0.9 degrees below average. That is not nearly as cool as our record-setting July 2014 when the average temperature was only 70.3 degrees (5.0 degrees below average). On the extreme other end, July 2012 was 81.8 degrees (6.5 degrees above average and the 2nd warmest on record). More on July temperature trends in another post.
