摘要：The world is undergoing a climate change followed by disastrous consequences. The warming of the planet that is growing shows this. Lomé, the capital of Togo, witnesses during these recent years, a sporadic wave of extreme heat, confirmed by meteorological data and by the work of many researchers that noted the growing of temperatures above the city. This research aimed to map the thermal status of the urban agglomeration of Lomé. Specifically, it is to determine the hottest area and the one at low temperature and to make a theoretical analysis in relation to the formation of the urban heat island in Lomé. The methodology used is based on records of daily temperatures of ambient air on twelve (12) observation posts installed in the urban agglomeration of Lomé. The collection of data from January 1 to December 31, 2016, preceded by the pre-collection of1st January to 30th June 2015 was directed at specific times of the day: 7AM; 1PM; 7PM; 12PM. The data processing by MS Excel revealed three (3) thermal areas. A low temperature area located on the outskirts and peripheral urban, an area with intermediate temperature at the center of Lomé Commune and a high temperature area that covers all the lower town of Lomé. The theoretical analysis states the gap in annual temperature average between downtown and the outskirts to 4°C. This gap exceeds 5°C during certain months. Therefore, Lomé houses phenomena of formation of momentary urban heat island (UHI).
