Sea of Oman — Iranian Coast

Oman Sea Coast is the Iranian portion of the Sea of Oman, stretching from the Strait of Hormuz east to the Pakistani border at Gwadar. Chabahar, Iran's only oceanic deep-water port — the country's sole non-Persian-Gulf access to open ocean — anchors this coast and has become strategically significant as an alternative trade route bypassing Pakistan for Central Asian landlocked states. Unlike the placid Persian Gulf, the Sea of Oman receives the full influence of the Indian Ocean, with the summer monsoon generating seas of 3 to 5 metres and the winter north-easterly producing consistent long-period swell. Tidal ranges average 1.0 to 2.0 metres, semi-diurnal, larger than in the enclosed Gulf due to the open ocean connection. The Makran coast, stretching east from Chabahar, is one of the most geologically active shorelines in the world — the Makran subduction zone has generated some of the largest tsunamis in recorded Indian Ocean history. Baluch fishing communities along this coast work a wild, exposed shoreline that most maritime trade routes have historically bypassed, giving it a frontier character unique among Iran's coastal zones.
