I remember vacationing in FL as a teen (and being stung solidly snorkeling once) and later with my children and often seeing many Man-O-War on the beach, jelly fish in the surf (thanks for the hint OB, I had no idea Man-O-War were NOT jelly fish) and beach closings when they were too numerous. I have not seen them in years. The furthest back anyone has mentioned in these articles is 20 years and the time frame I refer to is 30 - 40 years ago. It seems we have not kept records before now. In this case, I can't help but wonder about cyclic trends. I don't doubt the problems and nothing bad can come of our heightened awareness but I am not sold about this "sign"
