Relative humidity is a sensitive parameter in the sciences. It impacts the physical performance of electrical devices, metals, agro-food and biological items to name just a few. There are numerous factors such as dew point temperature, ambient temperature and solar radiation that can combine to influence relative humidity. There have been a handful of studies conducted on forecasting variations in relative humidity in the city of Biskra, Algeria. One typically finds that the dew point temperature is involved in variants of relative humidity, so we have been trying to predict it and create a semi-empirical equation as a function of apparent solar time, influenced by maximum and minimum dew point temperature, rather than create a new correlation related with ambient temperature. This study aims to contribute relative humidity as a function of the dew point temperature and validate it with experimental measurements.
