While I’m working on getting my pitch-by-pitch database up and running, I decided to have a little fun looking at the average game time weather conditions in the 30 major league ballparks, based on the weather information from Gameday.
The windiest park? AT&T/Pacbell/whatever it is these days in San Francisco. The calmest park? Besides the Metrodome (when they’re not turning on the air conditioning to blow opponents’ home run balls back into play), it is Safeco Field in Seattle. The following shows the average game time wind speed for each park. For parks with retractable roofs, the data is only for games when the roof was open at game time (and a wind speed was recorded).
The hottest park? Arizona’s Chase Field. The coldest park? San Francisco. Having experienced July in San Francisco and agreeing with Mark Twain’s sentiments, I can certainly believe that the new park is both the windiest and coldest on average. All thirty parks are listed below in order of average game time temperature.
