As of this morning I have not even seen a piece of jellyfish floating around! and the water has been just the way I ordered, PERFECT!!!!
My experience with jelly fish is that they get here when the humidity is so high is ready to rain or it has rain even if it is just for a few minutes and not a full rain it could be virga, not to be confuse with verga!!!
This year, as any other year, nobody knows when they are coming but the humidity and rain is a better indicator of their arrival than any date anybody will tell you, rarely you will see them in June the best answer will be that they come when the Monsoon season comes and remember only the idiots in TV will tell you Monsoon season starts in July 1st!!!
