With splitting aside, high rainfall at certain times of the fruiting stage definitely causes a watering down of a lot of fruits (I have noticed with not just tropical and not just with SFla). Off the top of my head I have seen mangoes, lychees, strawberries, tomatoes, watermelon having the flavor washed out due to excessive rain at the "wrong" time during their fruiting stage. Even tasted a fresh picked jacjfruit last week that sure seemed to be suffering from its texture being watery and flavor being washed out.
