Questions
When is the last frost in Indiana?
It depends on where you are. The typical last spring frost at Indiana's NOAA stations ranges from March 29 to May 2, and half of them have had it by April 21. Enter your ZIP code above for the station nearest you.
When is the first frost in Indiana?
Typically between October 9 and November 10, depending on the station; the median is October 21. Plan fall crops back from your own station's date.
What do "typical" and "safer" mean?
With the typical (50%) last-frost date, half of years still have a frost after it. With the safer (10%) date, only one year in ten does. In fall it's the other way around: the safer date is the earlier one.
