The USDA's 2023 Plant Hardiness Zone Map puts Redrock in zone 7b in ZIP code 88055, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, Redrock's NOAA station is in zone 8a: the coldest night of a typical year reaches 10°F (28 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.
