60% for most of the year. In the months from October to April, Kish's weather is mild, ranging from to .

With the exception of some southeastern coastal areas and a few other islands in the Persian Gulf, Kish Island has the most sunny hours in the region, roughly 3,100 hours per year. Based on climatological classification and general weather conditions, Kish's proximity to the Tropic of Cancer and its exposure to high tropical pressure systems, as well as its position amidst hot and shallow waters, means the island tends to be hot and humid most of the year. Tourist attractions Though Kish is a small island, it has numerous tourist attractions. The Greek Ship is the wreck of a 1943 cargo steamship, the Koula F, on a beach on Kish's southwest coast. She was originally a British ship, Empire Trumpet, and was built in Scotland. In 1966, she ran aground and all attempts to salvage her failed. When Koula Fs crew abandoned her, they set her on fire, and all that remains is her steel hull. Another attraction is the ancient underground aqueduct, also called the 'Underground City', which is partly open for tourists. It was built about 1,000 years ago for transportation and water supply across the different parts of the island. Other attractions include the beaches, which have a bluish tint, and the long shoreline that sees many tourists visit during the winter season. The water is so clear that fish can be seen swimming in the sea all year long.

The campaign has included massive construction projects and programs designed to attract foreign investment and trade.
