- First autumn frost, half of years before
- September 91 year in 10 before August 25; 9 in 10 before September 24
NOAA puts the median frost-free season at 85 days, and the season without a hard freeze (28°F) at 115 days.
A hard freeze (28°F) comes after June 2 in half of springs and before September 23 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Picabo in zone 6a in ZIP code 83348, 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 5b: the coldest night of a typical year reaches −14°F (26 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 Picabo 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.
