The average temperature for June in Illinois was 72.8 degrees, 0.9 degrees above normal, according to Illinois State Climatologist Jim Angel with the Illinois State Water Survey, part of the Prairie Research Institute at Illinois.
The statewide average rainfall was 3.27 inches, just 0.9 inches below normal.
“June had a split personality,” Angel said. “In the first 14 days, temperatures were nearly 4 degrees above normal with only a quarter inch of rain on average across the state. In the last 16 days, temperatures were almost 2 degrees below normal with 3 inches of rain.”
Rain in June varied across the state, with amounts of 5 to 10 inches along the Illinois-Wisconsin border, around Quincy, Iroquois County and in far southern Illinois. The rest of the state was much drier with only 2 to 4 inches of rain.
A stretch between Havana and Champaign received only 2 inches of rain for the month. The station reporting the most rain in June was Belvidere in Boone County with 12.08 inches. On the other extreme, White Heath in Piatt County reported only 0.65 inches.
