The weather and water will be nice. It's been a little hot lately, but that's what most people like when they come to the beach!
Seaweed is here, but not as bad as the past few years. Panama City Beach isn't bad at all, so I wouldn't expect Destin to be any worse. I'm not sure why your friend saw dead fish, but I haven't heard of any problems like that from anyone else, and I haven't seen any dead fish myself.
You picked a great time to visit Destin and I'm sure you will enjoy your vacation 100%! No worries!
