Mods, not sure if this is more appropriate in MLB or Stats, so feel free to move (obviously). Came across a two-part look at how temperature/weather impacts baseball by Jonathan Hale of Baseball Digest Daily. Pt. 1: "Some Like it Hot" Pt. 2: "Hot Spots & Cool Breezes" Honestly, there isn't much that you might not expect. However, it's interesting to see how the different MLB cities grade out in terms of temperature & wind. Hale also offers a cursory look at how FBs & CBs movement is affected by temp. "Not only do hitters have a very hard time in the coldest of weather, there is a steady climb from the worst numbers in the bitter cold up to the low 80's, where results level off. And the swing is significant- batters in weather under 50 degrees Fahrenheit average .249/.318/.410 while in a pleasant 81-85, they hit .297/.356/.468. I'm sure some of you have caught on to the fact that this could be putting the cart before the horse - maybe hitters are just catching up to pitchers as the year goes on and they shake off the rust of a long off-season, and temperatures just happen to be going up at the same time during the hot summer months. While that's possible that has an effect as well, except for a very poor April, last year hitters didn't do any better as the season went on"
