Frost Dates for 34452 — Inverness, Florida

Half of springs at Inverness 3 SE, FL see their last 32°F night by March 3; only one in ten is past it by January 31, and one in ten still has one after March 29.

The 26 days between the even-odds date and the one-in-ten date is wider than at 52% of the 101 Florida stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
