What moves the ball at Fenway Park
Elevation
Fenway Park sits essentially at sea level (21 ft, 24th of 30 by elevation). Air density here is about as heavy as it gets in MLB, so elevation adds nothing — temperature and wind decide how the ball travels.
Temperature
Warm air is less dense than cold air, so a hot night at Fenway Park carries better than a cold one with the same wind. Early-season and late-season night games here play noticeably heavier than mid-summer afternoons.
Humidity
Humid air is slightly lighter than dry air, so higher humidity helps carry a little — the opposite of what most people expect. It is a minor factor next to temperature and wind.
Wind
Home plate faces northeast, so a wind out of the southwest blows straight out to center and helps carry, while a wind from the northeast blows in and knocks fly balls down. Cross-winds push the ball toward one line — at Fenway Park the shorter right-field corner (302′) is where a helping wind shows up first.
