This study examines in detail the 10-year spatio-temporal variation in rainfall, temperature, and vegetation in Maiduguri and its environs. These include determining trends in rainfall, temperature, and vegetation over the 10-year period; examining the relationships among temperature, rainfall, and vegetation; and examining the relationship between surface temperature and rainfall. A simple linear regression analysis was deployed to analyse the data. The result shows that the regression coefficient (R2) of rainfall and vegetation is said to be R2=0.494, which indicates that there is a strong relationship between rainfall and vegetation, whereby the vegetation strongly depends on the rainfall. The regression coefficient (R2) for the relationship between temperature and vegetation in Maiduguri is 0.054, indicating a weak association and suggesting that vegetation in Maiduguri is not dependent on surface temperature. The final result concerns the relationship between temperature and rainfall, with an R2 of 0.006, indicating a weak association between the variables. This suggests that rainfall in Maiduguri is independent of local temperature.
