India has been identified as one among 27 countries which are most vulnerable to the impact of climatic changes and global warming relating to accelerated sea level rise. A mean sea level rise between 15 cm and 38 cm is projected by the mid 21st century along India’s coast. Climate is continuously varying on time scales ranging from seasons to the lifetime of the Earth. In this background there is about 15% projected increase in intensity of tropical cyclones in the coastal regions of India. The present study highlights weather changes between the years 2007-2008 in atmospheric variability over Kuttapuli coast, South Tamil Nadu, Southeast Coast of India. During this period atmospheric data viz. atmospheric minimum and maximum temperature, pressure, relative humidity, wind speed, direction, sunshine hours and rainfall measurement were collected. During this study period drastic variation could be observed in air temperature, wind speed and direction and rainfall. Thus it is imperative that year to year variation has started to prevail in this coastal belt, which is forming a vital zone of Gulf of Mannar.
