The region where Uluru lies – the southern part of the Northern Territory in central Australia – is a desert, where the average annual rainfall is about 300 mm, but even that is extremely variable. Although rain may fall at any time of the year in the vicinity of Uluru, occasional heavy rains occur between November and March. At such times, the famous monolith is covered with innumerable streams of water that changes the very color of Ayers Rock to a rare shade of violet.
It is estimated that only 1% of visitors to Uluru get the chance to witness waterfalls flowing from the rock.
