The USDA's 2023 Plant Hardiness Zone Map puts Lake George (8 mi SW) in zone 5b in ZIP code 80827, 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 4b: the coldest night of a typical year reaches −24°F (28 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.
