MLB WeatherEdge FAQ
How does WeatherEdge work? What do these numbers mean?
A: We charted the results and weather conditions for every game (since 2000). This tool makes an automated forecast for each upcoming game, then pulls in the results from games played in similar weather conditions at that particular ballpark. The results show us things like “how many more HR’s should we see when temps are 90 degrees at Wrigley”, or “how much will that wind blowing in impact runs scored tonight in Coors”.
How often is this product updated?
A: WeatherEdge automatically updates hourly. The forecast for each game is always adjusting to the latest model data.
What weather variables are included in this research?
A: Wind speed, wind direction, temperature, and dewpoint (a measure of humidity).
How far back does the data go?
A: For each ballpark the data goes back to the year 2000. For ballparks built after 2000, the data goes back to the first year of that ballpark.
Are the %‘s shown as compared to league average, or compared to other games played in that specific ballpark?
A: Everything in this tool is park specific. Comparing to MLB average would mean parks like Coors would always be a plus for hitters regardless of weather, and the purpose of this tool is to see how weather impacts each ballpark and each game.
