CHAMPAIGN, Ill. - The year 2011 was the 10th wettest year and a year of extreme monthly temperatures and precipitation, according to Illinois State Climatologist Jim Angel at the Illinois State Water Survey, University of Illinois at Urbana-Champaign.
The statewide average precipitation for 2011 in Illinois was 45.62 inches; 5.43 inches above the 1981-2010 average of 40.20 inches. It was also the wettest April, 8th wettest June, and 6th wettest November on record.
On the other hand, it was the 6th driest August and 21st driest October on record.
The statewide average temperature for 2011 in Illinois was 53.0 degrees; 0.8 degrees above the 1981-2010 average of 52.2 degrees. It was the 23rd warmest year on record. It was also the 4th warmest July, the 7th warmest November, and 8th warmest December on record. Yet it was the 17th coldest January and 10th coldest September since 1895.
