Global warming has been a source of concern in recent times due to its devastating effects on human life, water bodies, earth resources and vegetation. This results from the changes in climate elements of temperature, rainfall, sunshine hours, humidity and evaporation. In response, this research engaged the method of empiricism to determine the numerical values of most climate variables to enhance the understanding of climate conditions in Anambra – Imo River Basin within the periods of October to December 2011. In the research, it was discovered that the rainfall amounts were very small with high variability while the temperatures were very high. With this, further continuous periodic monitoring of the climate variables will create massive hydrometeorological data which will bridge the gap in the paucity of data in this area of study.
