The weather in Dongguan is very humid now. What is the reason?

besides high air humidity, it is also related to the recent rapid temperature rise. The temperature is rising rapidly, but the indoor temperature has not kept up, which is lower than the outdoor temperature. In this way, when the outdoor air with high temperature and high relative humidity arrives indoors, some water vapor will condense on the walls and floors, resulting in "condensed water". In addition to closing the doors and windows, you can also turn on the air conditioner for heating, so that the indoor temperature will rise, so that the condensation phenomenon will be significantly reduced. Once the temperature drops, the condensation will disappear immediately.
