The analysis of the trend in the Relative humidity and Dew point temperature, together with the assessment of the statistical significance between the two parameters received great attention due to its importance to global warming and climate change. The role that the Atmospheric water vapor plays as a greenhouse gas makes it one of the most significant determinants in the discussions of weather and climate. In the current study, the relationship between relative humidity and Dew point temperature at a location in the northern part of Nigeria (Abuja) for a whole year was analyzed. The results showed a very strong linear relationship in the two parameters especially in the dry season. The results also revealed a unique characteristic in the Dew point Temperature values of June, July and August that appeared at this station. The role the movement of the Inter-Tropical Convergence Zone ITCZ played in the results was also discussed.
