This study was designed to model the spatio-temporal pattern of Land Use/Land Cover (LU/LC) indices and its relationship with Land Surface Temperature (LST) in Ibadan Metropolis from 1988 to 2018. Four Landsat images of Ibadan metropolis for 1988, 1999, 2013 and 2018 were used in this study. Land surface temperature values of vegetation, open surfaces and built-up Land Use/Land Cover (LU/LC) analysis was carried out using ERDAS IMAGINE 9.2 in order to ascertain the areas covered by each land use type. The results of the study revealed that as the size of Built-up land use type increases and the size of the vegetation land use type decreases, the value of land surface temperature increases in relation to the increase in the size of built-up land use type and the decrease in the size of vegetation land use type from 1988 to 2018 in Ibadan Metropolis. This study can be useful in designing Urban Green Belts (UGB) and parks within the metropolis in order to mitigate problem of urban thermal discomfort in Ibadan, the state capital of Oyo State, Nigeria.
