Sindh and Balochistan Coast

Pakistan's coastline stretches 1,050 km along the Arabian Sea from the Indian border in the east to Iran in the west, divided between the flat delta coast of Sindh Province and the rugged Makran coast of Balochistan. The Indus Delta — one of the world's largest deltaic systems — sprawls across 600,000 hectares of tidal creek, mangrove, and mudflat east of Karachi. The Arabian Sea tidal regime along the Sindh coast is mixed semidiurnal with a mean spring range of approximately 1.5-2.5m at Karachi; the range decreases slightly westward along the Makran coast. The offshore Arabian Sea is influenced by two monsoon cycles: the southwest monsoon (June-September) brings swell and heavy rain; the northeast monsoon (October-February) brings calmer conditions. The Pakistan Meteorological Department (PMD) operates sea level gauges at Karachi and publishes tidal predictions; the Pakistan Navy Hydrographic Department publishes nautical charts and almanac data.
