Bahrain Coast

Bahrain is an archipelago of 33 islands in the Persian Gulf, connected to Saudi Arabia by the King Fahd Causeway. The Persian Gulf tidal regime at Bahrain is mixed semidiurnal with a mean spring range of approximately 1.5-2.5m — one of the larger ranges in the Gulf, driven by the Gulf's tidal resonance. The Hawar Islands in the south and the shallow tidal flats around them are critical habitat for the Arabian Gulf's dugong population — one of the largest remaining in the world outside Australia. Bahrain was the world's leading centre of natural pearl diving from the 3rd millennium BC until the Japanese cultured pearl industry collapsed the market in the 1920s-30s. The pearl diving heritage is UNESCO Intangible Cultural Heritage; the Qal'at al-Bahrain (Bahrain Fort) is UNESCO World Heritage. The Bahrain Meteorological Service and the National Maritime Safety Authority are the domestic authorities for weather and sea-level data; regional Gulf tide data is coordinated through the Arab Centre for the Studies of Arid Zones and Dry Lands (ACSAD).
