Guides

• How the RealWeatherCheck Comfort Score Is Calculated — The exact formula behind every city's 0-100 comfort score: mild months, seasonal swing, rainfall and snowfall, worked out on a real city.
• Why Some Cities Show No Snow or Rain Figure — NOAA's own normals omit snowfall for 2,151 cities and precipitation for 277 more. This site shows neither as a false zero.
• What a 30-Year Climate Normal Actually Is — NOAA recalculates its "normals" once a decade from a rolling 30-year record. What that means, and why it isn't this year's weather or tomorrow's forecast.
• Why This Uses the Nearest NOAA Station, Not Your Address — NOAA runs weather stations, not one per city. Real numbers on how far the average city here sits from the station its normals come from.
