West Lafayette — The arrival of fall means that the first frost likely isn’t too far off for most Indiana residents.
Purdue University reports that an analysis of historical temperatures recorded by the Indiana State Climate Office at the school shows that temperatures in Indiana typically have not fallen to the freezing point of 32 degrees before Sept. 23.
For most Indiana residents, the first freeze usually comes Oct. 12-16. The average date is two weeks later along the Ohio River in the south and along Lake Michigan in the north, where the lake is warmer than land this time of year. There’s a 90 percent chance that the first freeze will hit by Oct. 31.
Last year, freeze dates across Indiana ranged from Oct. 4 to Nov. 6.
