🏈 NFL Shade Finder standalone preview

The sun's exact position comes from the NOAA solar algorithm using each stadium's real coordinates, date, kickoff time and timezone, so the sunny vs. shady side and the timing are reliable. The seating bowl is split into ~120 individual sections (each sideline, end zone and corner, across lower/club/upper tiers); every section is ray-traced against the tiered bowl, oriented to the field's true bearing, so shade is shown section-by-section and animates through the game. Field orientation is pulled live from OpenStreetMap geometry where available ("map-derived"); otherwise a built-in estimate is used ("estimate"). The bowl geometry is a calibrated physics approximation, not exact per-stadium CAD, treat the shaded side, sweep and timing as the reliable signal, and exact section cutoffs as approximate. Domes are fully shaded; retractable roofs follow the toggle; open canopies (SoFi, Hard Rock, Lumen) shade much of the seating. Independent tool; not affiliated with the NFL or any team.
