<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>
