NOAA puts the median frost-free season at 206 days, and the season without a hard freeze (28°F) at 252 days.
A hard freeze (28°F) comes after March 20 in half of springs and before November 27 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts De Sabla in zone 8b in ZIP code 95954, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, the station is in zone 9a: the coldest night of a typical year reaches 20°F (21 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 De Sabla 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.
