The city of Addis Ababa was founded by Emperor Menilik in the year 1886. Since then Addis Ababa remained the capital city of the nations because of its location, hygienic conditions and material convenience. Addis Ababa is one of the fastest growing metropolitan areas in Ethiopia. The rapid urban growth the city saw in the last century resulted in tremendous land cover change dynamics within the metropolitan region. Particularly within the last 15 years rapid urbanization has consumed vast acreage's of land adjacent to the city. The urban heat island (UHI) effect in a large city, with a population of 2.42 million, examine on the influence of temperature, in central Ethiopia (Addis Ababa). UHI is related to the population of a town and have been studied extensively via direct observation. A direct warming of the air can result from various combustion processes such as those involved with vehicles, air conditioning and heating. Antropogenically induced changes in the energy balance in urban centers have a significant effect on temperature, which has been termed the Urban Heat Island (UHI) effect. The energy balance can also change as a result of land surface changes that included variations in the albedo, thermal aerodynamic properties, hydrology and morphology of the surface. The purpose of this investigation is to examine the current trends of urban heat island and its effects on the weather of Addis Ababa. The aim of the paper is to evaluate the potential impacts of urban growth on the temperature characteristics of the city.
