Indian High Sea
The northern Arabian Sea stretches south of the dry Makran coast and west of the Indus delta. Its waters form part of the sea routes between the Persian Gulf, Oman and western India. Sailors timed long crossings to the seasonal winds: the southwest monsoon carried ships toward the Indian coast, while the northeast monsoon favoured the return. Along Makran itself, the strength of the summer monsoon varied from one part of the coast to another.
