This paper aimed to evaluet the changes in the biophysical parameters and trends of the annual extremes of air temperature in Sinop, Mato Grosso, Brazil, using data from automatic meteorological stations (EMA) installed in the rural and urban areas of the municipality. The estimates of changes in soil use, surface albedo, radiation balance (Rn) and sensible heat (H) and latent heat (LE) were obtained by images from the Landsat 8 and Landsat 5 satellites in August of the years of 2007, 2011 and 2017. With the Rclimdex software, the trends of six extreme indices of the maximum, minimum and mean values of the annual maximum and minimum temperatures were calculated with least squares calibration and statistical significance considering the Fisher test with significance level equal to α: 0.05. It was observed changes in soil use and biophysical parameters like albedo increase and reduction of Rn in the rural area, while in the urban station (UFMT Sinop) occurred inversion of the ration of LE and H. The extreme indexes indicated a tendency of increase in the extreme temperatures in the urban area, being significant the changes in the indices TNx, DTR, Tn90p and Tx90p. In the last decade, with the expansion of the municipality of Sinop-MT, there have been changes in trends of temperature extremes indices, which are attributed to changes in soil use and biophysical parameters
