Half of springs at Childersburg Wtp, AL see their last 32°F night by March 31; only one in ten is past it by March 10, and one in ten still has one after April 16.

The 16 days between the even-odds date and the one-in-ten date is narrower than at 80% of the 115 Alabama stations behind this site's ZIP pages.
