What-If Simulator

Drag the weather and watch the game change. The same engine that scores real games, in your hands.

Set conditions and the Weather Football Index updates instantly, along with the scoring you'd expect from the historical record. Switch to Compare to pit two scenarios head-to-head.

Projected scoring maps the resulting WFI band to the average combined points of real outdoor NFL games in that band since 1999 (see the methodology). It's an expectation across many games, not a prediction for any single one — scheme, injuries, and matchup dominate. Domes and closed roofs correctly crush the score toward zero.
