- February 121 year in 10 after March 10; 9 in 10 after January 10
- First autumn frost, half of years before
- December 61 year in 10 before November 16; 9 in 10 before January 7
NOAA puts the median frost-free season at 302 days, and the season without a hard freeze (28°F) at 341 days.
A hard freeze (28°F) comes after January 25 in half of springs and before December 31 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Anahuac in zone 9b in ZIP code 77597, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, Anahuac's NOAA station is in zone 9a: the coldest night of a typical year reaches 24°F (19 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 Anahuac share this climate record?
6 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.
