This study evaluated rainfall and temperature variation in Yola metropolis, Adamawa State, between 2008 and 2018. The data used was obtained from the Nigerian Meteorological Agency (NiMet). Mann-Kendall’s trend test was used to analyse the data on mean temperature (minimum and maximum) and annual rainfall. The results of the study revealed that the minimum temperature is increasing and the maximum temperature is decreasing in the area, while rainfall is increasing. There is also no significant change in the period of onset and cessation of rainfall within the period of study. In this regard, farmers in the region are advised to maintain their normal period of farming activities. Based on these findings, residents of the area are encouraged to build houses that allow for good ventilation to minimize heat stress, keep water drainages clean, and avoid building structures and farming on waterways to prevent flooding and destruction of farm produce during the rainy season.

Keywords: Temperature, rainfall, variability, flooding, Yola Adamawa state
