Wettest May to July Ever in Illinois

Illinois experienced its wettest May – July on record with 19.69 inches of precipitation, 7.88 inches above the 20th century average, according to the National Centers for Environmental Information.

Most of that was due to the record precipitation of June with 9.44 inches statewide.

The second wettest May – July was a tie between 1990 and 2010. And it was just three years ago, in 2012, when Illinois had its third driest May – July on record with only 5.60 inches (6.21 inches below the 20th century average).
