The lack of comprehensive information on the climate of the coastal region results in insufficient understanding of the impact of changing climate on the coastal ecosystems and also impedes in framing suitable climate-based adaptation strategies and policies at the regional and local level. Monitoring current climate change demands a historical perspective, as much as possible, and framing a baseline climate data is important for establishing a reference point to assess climate change. Thus, the study of past climate change relies critically on the availability of datasets that characterize the climate of the region. In this context, the objective of this article is to provide climate portfolio (collection of climate information) of Pichavaram mangrove region of Tamil Nadu coast, India, and to give an outline of its predicted impacts. Climate data of the past 60 years have been collected, and the trend analysis of major climatic variables such as temperature, rainfall, relative humidity and wind speed has been studied statistically. This research article critically appraises the available climate data, identifies general patterns of climate change in the coastal region and highlights the gaps in existing knowledge on the impact of climate change at the local level. It gives a holistic approach on understanding climate at local level and provides baseline climate information. This, in turn, is expected to shore up in framing suitable adaptation strategies and policies for the coastal region with the most valuable ecosystem such as mangroves.
