Sydney’s beaches turn blood red as swimmers forced to stay out of water

SOME of Sydney’s most famous beaches have been forced to close after the water turned blood red.
A thick algal bloom known as noctiluca scintillans – the "red tide" or "fire in the sea" – began washing up on beaches during early morning.
The bloom is capable of causing skin rash and eye irritations and Bondi and Clovelly beaches were the first to close but some re-opened later.
It is understood the natural phenomenon was caused by high temperatures and more movement in sea currents.
