Half of springs at San Saba 7NW, TX see their last 32°F night by March 16; only one in ten is past it by February 26, and one in ten still has one after April 8.

The 23 days between the even-odds date and the one-in-ten date is wider than at 72% of the 339 Texas stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
