have you spent much time in florida or parts further south? most of the time the forecast has rain in it. sometimes everyday. it is usually passing showers, is usually warm and humid (which makes it feel warmer). on a ship they try and avoid the big storms if there are any. truly being rained to to the point of not being able to so things is pretty rare? but think about a day at WDW pretty much july-october = thunderstorm at some point during the day. you will have a great time! great time of the year to cruise!!
