Nanjing used to be called "heater" in July and August sometimes can reach as high as 40℃. The average temperature in this period is about 35℃. However, Nanjing has been a national green city in recent years, with urban greening rate of more than 30%. So more and more people like to travel to Nanjing in summer. "Heat summer and cold winter" is the obvious feature of Nanjing, so Nanjing’s climate is worse than the other significant weather features.
