How a ZIP code gets its number
Each ZIP code is placed at the Census Bureau's centre point for its ZIP code tabulation area. The reading is NOAA's Global Forecast System (GFS) soil temperature for the 0–10 cm layer (0 to 4 inches) at the nearest land grid point of its 0.25° grid, about 25 km apart, so neighbouring ZIP codes often share one value. ZIP codes more than 30 km from a land grid point have no page. It is a model value, not a probe in your yard: against NOAA's 108 reference stations the daily average is off by 4.2°F on average. A soil thermometer at 4 inches is the check for one lawn; how to measure it.
Data: Global Forecast System (GFS) 0.25°, soil temperature 0–10 cm (TSOIL) (NOAA National Centers for Environmental Prediction (NCEP)); 2025 Gazetteer ZIP Code Tabulation Areas (ZCTA) and 2024 cartographic boundary state outlines (U.S. Census Bureau).
