The USDA's 2023 Plant Hardiness Zone Map puts Huntsville in zone 6a in ZIP code 84310, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, Huntsville's NOAA station is in zone 5b: the coldest night of a typical year reaches −15°F (21 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.
