The USDA's 2023 Plant Hardiness Zone Map puts Echo in zone 6a in ZIP code 84024. By the map's own method, the average of each year's coldest night over 1991-2020, Echo's NOAA station is in zone 5b: the coldest night of a typical year reaches −14°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 Echo share this climate record?
Henefer has no NOAA station with 1991-2020 normals of its 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.
