What a difference in temperature between July 2012 and 2013. Last year we were in the midst of a full-blown drought and heat wave with temperatures routinely in the 90s and low 100s. The statewide average temperature for July 2012 was 81.8°F (6.5°F above the 1981-2010 average) and the second warmest July in Illinois behind the record of 83.1°F in 1936.
This July has had its hot and humid moments, but for the most part has been mild overall in Illinois. The statewide average temperature for July 2013, as of July 29, is 73.6°F ( 1.7°F below the 1981-2010 average) and the 23rd coolest July on record based on preliminary data.
The cool July weather was confined to the central and southeastern US. Meanwhile, both the western and northeastern US have experienced warmer than average temperatures this month.
