temperature affects relative humidity
As you may know, humidity is the amount of water vapour in the air. (Along with being something that can turn a great hair day into a bad hair day!) So, what does temperature have to do with it?
Warm air holds more water than cold air. Therefore, when the temperature increases, more water vapour can be held in the atmosphere, causing the humidity to rise. When the temperature decreases, less water vapour can be help in the air, causing the humidity to lower.
