You are hot and farting fire like a friend of mine.I've been to Israel near the same sea, I've been to Italy near the same sea, I've been near Baltic and Black seas, I've been to both coasts of USA.
Also, you cannot have higher humidity than 100% and this is what you have practically everywhere near big body of water (lake, sea or ocean) at these temperatures.
So, please, spare me the "humidity" baloney, would you - it is easily bearable when you are properly dressed.
PS. Like I said - these rumors are started by Lebanon, not by Israel.
