Cold weather makes home runs harder at GABP

Posted: Updated:

Great American Ball Park is known as a "hitters" park. 

It's dimensions… left field foul pole: 328 feet; left field power alley: 379 feet; center field: 404 feet; right field power alley: 370 feet; right field foul pole: 325 feet…certainly help in that regard. 

According to, "since it opened in 2003, Great American Ball Park has featured more than 2,017 home runs."  

In contrast, Coors Field in Denver has yielded in the neighborhood of 1,762.  As it turns out air temperature and air pressure play a pretty significant role in how far the ball flies.

When air warms, it expands. This warming and expansion lowers the density of the air. This produces longer flight. 

Thanks to warm air being less dense than cold air, it's much easier to hit a home run on a warm day than a cool day.   

Additionally, air pressure affects air density.   

At higher elevations, air has lower density. When the air density is lower, baseballs can travel further.   

Air rubbing against a baseball produces friction.  The lower the air density, the smaller this frictional force becomes

A ball park near sea level is tougher to hit a homer in than say, a ball park at a higher elevation (for example Denver). 

Coors Field, at a mile in elevation can add some 20-40 feet to a ball screaming into the outfield because of the lower air pressure 

So, if you were wondering about some of the long fly balls Tuesday night at GABP, the cooler air (and somewhat higher pressure) played a role in helping to keep them in the park.

If you are headed to GABP for game 4 of the NLDS, bundle up!

Temperatures at 4:00 p.m. at the stadium will be in the upper 50s with a wind chill in mid 40s.

The temperature will drop to the mid 40s by 9pm with a wind chill around 40º. GO REDS!!!!!!
