Why doesn't the weather in Nanjing exceed 40 degrees?

The measured temperature has a deviation.

The collection point of urban weather forecast is set in an open and well-ventilated place. Under the sun exposure, there is a temperature difference between the measured temperature and the actual temperature. This is also the reason why the published temperature is still relatively low in many cases, and it is difficult to reach more than 40 degrees, which is a very high temperature.
