Oman’s amazing overnight transformation from arid desert to breathtaking rainforest has been revealed in a series of photographs.
The once-a-year sensation, which is known as the Salalah Khareef, or the Salalah Monsoon, transforms a huge tract of land seemingly overnight into a picturesque emerald haven for locals and animals – including hundreds of camels.
It takes place for three months a year, from the end of July to the beginning of September, and sees average temperatures drop from a scorching 50 degrees to a cool 20.

The dry conditions nine months of the year means that Salalah does not have permanent lakes or running rivers – but during the monsoon waterfalls can be seen flowing over the cliffs.
