2nd Wettest June on Record

Illinois has experienced the 2nd wettest June on record, based on preliminary records through June 30. The statewide average rainfall was 7.8 inches, 3.7 inches above normal. The wettest June on record was 1902 with 8.37 inches. The rains over the weekend, especially north of I-80 and along I-70 caused this June to move up from fourth to second wettest June on record. Statewide records extend back to 1895. This number is provisional and may change slightly as more data comes in.

The larger rainfall totals occurred in the northern two-thirds of the state where amounts of 7 to 12 inches were common.  Meanwhile far southern Illinois remains closer to normal with amounts ranging from 3 to 6 inches.
