Abstract The effects of Urban Heat Island (UHI) have intensified with greater urbanization and industrialization of the natural environment. The objective of this work is to identify the formation of UHI in an industrial district based on the analysis of possible correlations between the variables that influence the urban microclimate. In this context, it was proposed to collect data in situ for 15 days on temperature and relative humidity in an industrial district (DI) and a central residential area (R) in Uberlândia/MG. To estimate the UHI intensity, data from the meteorological station located at the airport were used, whose maximum peak occurred at 9 pm, reaching 1.5ºC for R and 5ºC for DI. It was found that in the R area, the variables wind speed (WS) and Sky View Factor (SVF) (0.505), relative humidity (RH) and turbulent kinetic energy rate (TKE) (0.603) are strongly positively correlated, air temperature (Tar) and relative humidity (RH) established a strong negative correlation (-0.981); in the industrial section (DI), the variables with strong correlation were LST and Tar (0.603), SVF and WS (0.704), WS and Wind direction (WD) (0.643), WD and SVF (0.694) and again RH and TKE (0.705), demonstrating the importance of wind for this location, especially when it is favored by the orientation of the main streets. Given the intensity of UHI recorded and the most impactful variables detected for the DI, urban planning with a focus on better distribution and layout of streets and avenues and greater afforestation of the space and judicious application of surface materials could contribute to cooling the área.
