The USDA's 2023 Plant Hardiness Zone Map puts Langtry in zone 8b in ZIP code 78841, 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 9a: the coldest night of a typical year reaches 21°F (24 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.
