Cities are exposed to a microclimate, where temperatures are usually warmer at downtown than outskirts. The intensity of global warming depends on the temperature gap between the downtown and the outskirts of the city known as the urban heat island phenomenon (UHI). Lomé faces intense waves of heat and warming whose temperature gap is 4°C. The purpose of this research is to identify the urban parameters that influence the warming of Lomé. The method is based on the delimitation by remote sensing of one site in hot area and one another in a less hot area using images of the Quick bird satellite with high resolution (0.6m) dating from the month of January 2016. The data collection is relative to a group of 4 main urban parameters namely the area of vegetation on the floor, the naked or built soil, urban traffic and the size of the population. Comparison of values of these parameters on the sites has proven that the vegetation cover only is not in favor of urban warming. Therefore, the city of Lomé is warming by intensive mineralization.
