Dont know about it being cooler,
its sweltering here 
Stacks of people in the sea all day long.
I have heard that there is a flag that will now be flown along side the usual red, amber or green ones.
I havent actually seen the new flag myself, well, I dont really want too, it means a jelly fish invasion,
but it has two jelly fish on it ...kindda like two squiggles.Regardless of what colour flag is flying, the jelly fish warning one will be flown when needed..... along side the usual sea current warning flag.
