Temperature is the focus of many studies around the world due to several factors, such as population growth and land use and coverage changes, as these elements contribute to the increase/decrease of air temperature on the surface of a region. This study aimed to analyze the temperature trend in the metropolises of the Brazilian Amazon (Belém and Manaus), from 1978 to 2018, for the dry and rainy regimes, taking into account population growth and the change in land use and coverage of referred cities. For this purpose, monthly data of maximum, compensated and minimum temperature in a radius of 25 km from the coordinates of the meteorological stations of each city were used, extracted from the National Institute of Meteorology, usage data and coverage of the Annual Soil Coverage and Use Mapping Project in Brazil and population data of the Brazilian Institute of Geography and Statistics. The results showed a positive trend in the temperature of these regions studied, due to the increase in urban infrastructure and population growth, as well as a decrease in forest formation in the metropolises of the Brazilian Amazon.
