ParkFactors.com is brought to you by ScoutingBook.com, using weather information provided by the national weather office. Wind direction is averaged to the nearest cardinal point and adjusted to ballpark orientation. Wind descriptions are provided using the Beaufort Standard Scale of wind terminology, ranging from 'still air' to 'hurricane' force. Park Factor is calculated differently by different analysts. Our Park Factor summary formula uses the mean of runs scored and home runs hit per game at home vs away, where 100 would be a perfectly-average park.
