In this paper we consider the Zhoushan Islands area to check the sea level (SL) variation. Sea Surface Height Relative to Geoid over the Zhoushan Island area has been obtained from the operational data sets produced routinely by the Global Ocean Data Assimilation System (GODAS). Monthly, seasonal and interannual variations have been presented and possible relations for variations are also explained. SL is indicating a decreasing trend, however there is an increasing trend before year 2000 and showing decreasing trend after 2000. There is 5 mm increase in SL before 2000 and 10 mm decrease in SL after 2000. Over Zhoushan, Sea surface temperature (SST) is having an inverse relation with SL, however SL is having a positive relation with Nino 3.4 SST anomalies but it is not significant.
