Does humidity increases after the rain?

After the rain, humidity typically decreases rather than increases. When rain falls, it often signifies a change in weather conditions. Rain is associated with the passage of a weather system, which is often followed by clearing skies or a decrease in cloud cover. After the rain stops, the air tends to become drier, leading to a reduction in humidity.

Here’s why humidity decreases after the rain:

  1. Rainfall Clears the Air: Rainfall helps clear the atmosphere of dust, pollutants, and other particulates. As the raindrops fall through the air, they can capture and remove particles from the atmosphere. This purification process leads to cleaner air with lower moisture content, resulting in decreased humidity.
  2. Evaporation and Drying: After the rain stops, the moisture on the ground and surfaces begins to evaporate. As the sun comes out and temperatures rise, the evaporation process accelerates, removing moisture from the environment and reducing humidity levels.
  3. Post-Rain Conditions: After a period of rain, the air may feel cooler and more comfortable. Cooler air has a lower capacity to hold moisture, so relative humidity tends to decrease.

While humidity can increase during rainfall due to the release of moisture into the atmosphere, it generally decreases once the rain has stopped and the air begins to dry out. It’s important to note that weather conditions can vary, and local factors, such as temperature, wind, and vegetation, can influence humidity patterns after rain. However, the general trend is for humidity to decrease as the air dries out following a rain event.
