Current Weather Conditions and HRF Index

The table below shows the Home Run Forecast Index (HRFI) value for each big league ballpark. The HRFI ranges from 1 to 10, with 10 indicating the most favorable weather conditions for ball fight and 1 indicating least favorable. Learn more about how we calculate this index here.

This data is updated hourly at the top of the hour. For ballparks with a retractable roof, the index is calculated for open roof conditions. Check local sources for roof status. For ballparks with a permanent roof, the index is calculated for indoor conditions.
