What it measures

Weather Impact Score identifies how much a player's fantasy production varies based on environmental conditions including temperature, wind speed, precipitation, playing surface, venue type, and home/away splits.

Inputs

  • Game-level fantasy points: Per-game PPR scoring across 2023–2025 seasons.
  • Weather conditions: Temperature, wind speed, and precipitation for each outdoor game.
  • Venue and surface data: Dome vs. outdoor, turf vs. grass, retractable roof status.
  • Home/away designation: Game location relative to the player's home stadium.

Scale

  • Below 3.0: Weather-proof - consistent production regardless of conditions (green).
  • 3.0 – 4.9: Moderate sensitivity - some weather-driven variance (orange).
  • 5.0+: Heavily impacted - production swings dramatically with conditions (red).

How to use it

  • Before weekly start/sit decisions, check Weather Impact for players facing adverse conditions.
  • Target weather-proof players for playoff weeks when conditions are unpredictable.
  • Pair with weekly projections for weather-adjusted fantasy point estimates.

Limitations

  • Requires minimum 2 games per condition bucket, which limits granularity for newer players.
  • Indoor players (dome teams) have limited weather data and may show artificially low scores.
  • Does not account for altitude or humidity effects on performance.
