The purpose of this study is to assess the spatial distribution of ocean wave parameters, and their correlation and anomalies in the Bay of Bengal (BoB) using about 40 years of ERA5 reanalysis data. Collected data were analyzed by using geographic information system (GIS) and computer programming languages. It is revealed that higher values of SWH (2.50–2.58m) dominated the central, southern and south-western BoB during June–August. The monthly climatological mean of MSS and Cd are ranged from 0–0.013 and 0.0006–0.0016 respectively in the study area. WSP were higher (10.31–10.84m/s) in southwestern BoB during June–August. Tm is higher (11.23–11.03s) during April–September in southern and south–eastern BoB. Lower Tm (2.36–2.73s) is found in western and eastern BoB. SWH, WSP, Tm, MSS and Cd have unfolded significant impact on each other during most of the month. Strong anomaly has been reflected in the SWH, WSP, and Tm during March–April.
