The USDA's 2023 Plant Hardiness Zone Map puts Tupper Lake in zone 4a in ZIP code 12986, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, Tupper Lake's NOAA station is in zone 4b: the coldest night of a typical year reaches −24°F (24 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.
