One can forecast wave climate for availability of living treasures to avoid famines and for ship routing to avoid navigational disasters. Study of wave climate is helpful for planning and development of coastal areas, off-shore petroleum explorations, marine mining and marine engineering. Very little work has been done in the northern Arabian Sea. Availability of instrumentally measured waves around whole of the Arabian Sea is very limited. Neither such data are available in published literature nor can it be obtained elsewhere. Data for the analysis of wave pattern have been collected with the collaboration of the Hydrography Department, Port Qasim Authority during southwest monsoon season only as in the northeast monsoon no noticeable waves are formed except ripples. Present work is not only useful for Port Qasim but also constitutes an account of the wave climate for this region. Marine activities like offshore mineral and oil exploration, utilization of water and energy, designing and construction of marine structures and harbours, shipping and naval activities require accurate information on wave climatology, which is now available in this monograph.
