The seasonal variations of physico-chemical parameters were studied during July 2014 to June 2015 in the Agniar estuary (Lat.10° 20' N Long.79° 23’E ) Adirampattinam southeast coast of India. The atmospheric and water temperature ranged from 28.8ºC °C to 35.2°C and 26°C to 31.4°C respectively. The pH ranged between 7.3 and 8.6. The DO was ranged from 3.8 to 7.3 ml/l. Salinity fluctuated between 1.5‰ and 33.8‰. The DO was found to be low in summer and high during monsoon season. Similarly temperature, pH and salinity were low during monsoon and high during summer season.
