Abstract
The influence of weather in all aspects of human endeavours is evident in the recorded loss of lives and properties due to weather related disasters usually triggered by global climate changes. Hence, the need for the collation of information about the temporal dynamics of weather changes is of paramount interest. This research was aimed at determining the relationship between relative humidity and the dew point temperature in Benin City, Edo State, Nigeria. The dew point temperature was approximated from the measured air temperature and relative humidity with the aid of a currently self-designed weather monitoring system. The results showed that the relationship between the relative humidity and the dew point temperature were linear with significant coefficient of determination (R 2 ) of 0.79. The relative humidity and the dew point temperature are prospective tools in weather prognostications and are used to express the amount of moisture in the air, this would help guide against the occurrences of climatic induced environmental disasters in our communities.

Highlights
Weather and climate changes have always been an issue of great interest; in recent times is becoming a universal concern especially its effects on our environment
These values were in good conformity with weather data obtained from other sources
The results of this study showed that the dew point temperature for Benin City, Edo State, Nigeria was as low as 13oC during the month of January, 2016 which was the month of the lowest relative humidity (40%)
Summary
Weather and climate changes have always been an issue of great interest; in recent times is becoming a universal concern especially its effects on our environment. Weather is used to describe the momentary atmospheric conditions at a certain place. It is the state of the atmosphere of a given place at a particular time. In describing the atmospheric conditions of a given place at a given time, certain weather elements or parameters must be known, measured and quantified. Some of the most crucial weather elements are temperature, relative humidity, atmospheric pressure, wind speed and direction, precipitation, dew point temperature, altitude, solar or light intensity (Karl, 2014; Akhilesh et al, 2015; Akpan et al, 2016; Ukhurebor et al, 2017). The regression equation was obtained using the curve estimation procedure to determine the relationship between relative humidity and the dew point temperature for Benin City, Edo State, Nigeria from the pooled data
