The Summer Solstice (Xia Zhi, 夏至 in Chinese) is the 10th term of the 24 traditional Chinese solar terms (a supplementary system in the Chinese calendar to guide farm work) and falls on sometime between June 21 and June 22, when the sun moves to the celestial longitude of 90 degrees. On the day of the Summer Solstice, the sun moves nearly above the Tropic of Cancer, when the northern hemisphere has the longest sunshine day in a year.

After the Summer Solstice, the subsolar point will move toward south, and the sunshine dwindles day by day in the northern hemisphere.

The coming week will see intermittent showers with a slight drop in air temperature for 5 consecutive days. So it will be a little bit cool in the following days.

After the rain subsides, it will get cloudy in most areas of Chengdu. In next week, the average air temperature will be between 23 and 31 degrees centigrade, the air humidity between 60-84%.
