Abstract

The winds in the Lakshadweep are predominantly northwest throughout the year with higher speeds in the range 5–8 m/s during June through August, the southwest monsoon season. The wave climate of the Lakshadweep Sea is dominated by the southwest monsoon. The highest wave heights are observed during the period from June to August with the dominant values of maximum wave heights around 5 m. During the rest of the period it was around 1.4 m. Higher wave periods are observed in February and April and the lower ones during June–August. The dominant zero-crossing period during the southwest monsoon is in the range 7–8 s and in the rest of the months it varies from 5 to 10 s. South-southwesterly waves dominate during most of the periods except during the peak southwest monsoon when west-southwest to westerly waves dominate. The inner-shelf currents are generally weak with northeast to southwest directions. The tide in the Lakshadweep Sea is mixed, semidiurnal and micro-tidal type.
