<Li> 42,411--Games 3 & 4 of the 2015 NLDS </Li> <Li> 42,445 - Game 3 of the 2017 NLDS </Li> <P> In April and May the wind often comes off Lake Michigan (less than a mile to the east), which means a northeast wind "blowing in" to knock down potential home runs and turn them into outs . In the summer, however, or on any warm and breezy day, the wind often comes from the south and the southwest, which means the wind is "blowing out" and has the potential to turn normally harmless fly balls into home runs . A third variety is the cross-wind, which typically runs from the left field corner to the right field corner and causes all sorts of havoc . Depending on the direction of the wind, Wrigley can either be one of the friendliest parks in the major leagues for pitchers or among the worst . This makes Wrigley one of the most unpredictable parks in the Major Leagues . </P> <P> Many Cubs fans check their nearest flag before heading to the park on game days for an indication of what the game might be like; this is less of a factor for night games, however, because the wind does not blow as hard after the sun goes down . </P>
