When is the last frost in Jacksonville?
In Jacksonville, the last spring frost (32°F) comes after February 25 in half of years and after March 19 in one year in ten; the first autumn frost comes before December 7 in half of years and before November 17 in one year in ten.

- Last spring frost, half of years after
- February 251 year in 10 after March 19; 9 in 10 after January 22
- First autumn frost, half of years before
- December 71 year in 10 before November 17; 9 in 10 before January 10
NOAA puts the median frost-free season at 288 days, and the season without a hard freeze (28°F) at 325 days.
A hard freeze (28°F) comes after February 4 in half of springs and before January 2 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Jacksonville in zones 9a to 9b across its 32 ZIP code areas (9b in 32218, the largest). By the map's own method, the average of each year's coldest night over 1991-2020, Jacksonville's NOAA station is in zone 9a: the coldest night of a typical year reaches 24°F (30 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.

Which places near Jacksonville share this climate record?
2 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
