The Red Sea is world renowned for its superb diving and is home to some of the best, most exhilarating underwater scenery in the world. Its corals are richly hued in colour, abounding with hundreds of species of fish from the diver’s favourite clown fish, (Nemo’s runaway brother), to moray eels, manta rays and if you`re really lucky you may even see sharks.
The Red Sea was formed around 40 million years ago and takes its name from certain algae which form a red outer coating that turns the sea red during seasonal blooms. Watching a sunset in Dahab gives the impression that the surrounding mountains themselves create the reddish hue of the sea.
The Red Sea has no freshwater influents, and the limited circulation with the Indian Ocean only just allows enough water volume compensation for evaporation, Thus we have a strong salinity percentage here compared to other seas, in fact amongst the highest on the planet. Volcanic activity on the sea bed means that the Red Sea is also warmer than other seas. At 1km the Indian Ocean water temperature registers around 6-7 degrees. At the same depth, the Red Sea reads an astonishing 21 degrees. The hottest on Earth.
