What is the general air humidity in arid climate?

The air humidity in arid climate is usually very low, generally lower than 30% relative humidity. In a dry climate, water evaporates quickly, resulting in low air humidity. Such climatic conditions will make the soil and plants lose water and lead to drought. However, the specific air humidity will also be affected by many factors such as region, season and weather, so not all dry areas have the same air humidity. If you need to know the air humidity in a specific area, you can refer to the relevant temperature and humidity data records or reports of the local meteorological bureau.
