Which city in China has the lowest temperature in summer?

The city in China with the lowest temperature in summer is Lhasa.

The low temperature in Lhasa is related to the terrain and surface morphology. Lhasa belongs to the plateau, with an altitude of 3,650 meters, a high altitude. High altitude and low air pressure contain less gas per unit volume, absorb less temperature, and have weak thermal insulation effect. Therefore, the temperature in high altitude places is lower than that in plains at the same latitude.

The Northern Tibetan Plateau in Lhasa is the place with the lowest temperature in China. The Northern Tibetan Plateau is the place with the lowest summer temperatures in China. The northern part of the Northern Tibetan Plateau, with an altitude of 4,700-5,500 meters, has a plateau frigid monsoon arid climate. The average temperature in the warmest month is below 6 degrees Celsius, and the annual precipitation is 100-150 mm. It is a vast natural pasture. Areas above 5,500 meters above sea level are covered with snow all year round, making it a world of ice and snow like crystal beads and broken jade.
