What month is the rainy season in Henan?

March. In March, the weather in Henan began to get warmer, the temperature rose and the humidity was relatively high. This kind of climatic conditions can easily lead to the condensation of water vapor in the atmosphere to form weather phenomena such as rain and fog, thus forming misty rain, and at the same time, cold air interacts with warm and humid airflow to form cyclone activities. Cold air causes the temperature to drop, and the combination of relatively low temperature and relatively high humidity is easy to form rain fog and misty rain.
