How these scores are made
  • The score is the Weather score, out of 100, for the 200 minutes starting at kickoff. It is averaged over every regular-season Saturday from Aug 29 to Dec 6, 2018 to 2025, and over noon, 3:30 and 7:30 starts.
  • Readings come from an airport weather station near each stadium, not from the stands. Shade, delays, smoke and indoor roofs are not in it. A few stadiums use an airport farther than the nearest one, because the nearest has too little history; their cards say how far.
  • The comfortable stretch of 60 to 75°F is our choice. Moving it changes the order, mostly among the hot places.
  • Stadiums near the same airport share a score. Ranks come with a range, because the eight-season average carries about a point of year-to-year noise; a single season can swing 2 to 3 points.
  • An airport reading can run warmer or cooler than the stands, and most for a stadium by a lake or the coast. Some airports missed a few kickoff times to outages, and those are left out, not filled in.
  • A few airports have a rain gauge that does not report rain. Where a working gauge sits within 25 km, the rain comes from it; where none does, the score has no rain term. The card says which.
  • It describes what these Saturdays were. It is not a forecast, and it says nothing about home advantage. Indoor stadiums are not scored.
