The effect of the urbanization on temperature and on rainfall is studied by analyzing observational data. The primary data used are observations from Port Area and Science Garden.These correspond to locations in the urbanized area. These observations are upplemented by observations at rural areas. The analysis shows a definite warming trend. This trend is equivalent to an increase of about three degrees per century. The analysis of the rainfall data indicates no appreciable increase in rainfall in the urbanized area.
