2015 Climate by the Numbers in Illinois

Here is a quick update on the statewide monthly temperature and precipitation departures from average for 2015 in Illinois.

February 2015 stands out as a painful reminder of how cold it was late in the winter. However, both April and May have been warmer than average. All together, the average temperature of the first five months of 2015 stands at 40.5 degrees, 2.3 degrees below average.


The statewide average precipitation for January – May 2015 was 14.09 inches, 1.37 inches below average. Illinois was drier than average for the first 4 months of 2015. It was nothing like 2012, but it did raise some concerns. May has erased most of those concerns with widespread above-average rains.
