The Camping Weather Index scores every U.S. city 1–10 for overnight comfort — overnight low, daytime high, wind, humidity, and rain weighted for what actually makes or breaks a night under the stars.
The Camping Weather Index scores each U.S. city from 1 to 10 using National Weather Service NDFD forecast data at 2.5km resolution, updated every morning. Six factors are scored and combined — five on days 4–6 when precipitation data is unavailable. Overnight low temperature is the primary factor, since sleeping comfort is the core camping experience.
A score of 10 means near-perfect camping conditions. A score of 1 means conditions are poor — too cold, too windy, or too wet to camp comfortably. The index covers the contiguous United States with 37,000+ city data points.
