Salalah is the second largest city in the Sultanate of Oman, and the largest city in the Dhofar Province.

Salalah is the birthplace of the Sultan Qaboos Bin Said 

The climate of the region and the monsoon allows the city to grow some vegetables and fruits like coconut and banana.

Salalah is one of probably only two places in the Arabian peninsula besides Yemen that experiences a monsoon season, which is called Khareef and this lasts from July to September. Khareef means autumn in Arabic but interestingly it refers to monsoon when describing Salalah. 

During this time, the brown landscape of Salalah and its surroundings is completely transformed to a beautiful and lush green, and locals and tourists a like flock to Salalah.
