This paper aims to determine and explore the relation with industrialization with Urban Heat Island (UHI). UHI is a phenomenon of accumulation of more temperature than rural areas. The metropolitan cities like Delhi, Mumbai, Ahmadabad, Kolkata, Bengaluru etc. These are the cities grown rapidly in present scenario. The mechanism of UHI, implications of it is in these metropolitan cities are overview of this research work. It includes collection, analysis of data related to UHI. Finally, it reveals the effect of UHI in different metropolitan cities. Increase in solid waste generation, air quality alteration, loss of aquatic life, air pollution, rise of skin diseases, asthma, respiratory problem etc. The objective of this paper is to understand the mechanism of the UHI process and its implications in different metropolitan cities by analyzing with parameter like raise in city temperature, thermal discomfort, pollution level, uneven rainfall, and increase in flood level.
