The Gulf of Aden in the west connects the Arabian Sea to the Red Sea through the strait of Bab-el-Mandeb, and the Gulf of Oman is in the northwest, connecting it to the Persian Gulf.on the southwest by the Somali Sea, and on the east by India. Its total area is 3,862,000
The Arabian Sea has been crossed by many important marine trade routes since the third or second millennium BCE. Major seaports include Kandla Port, Okha Port, Mumbai Port, Nhava Sheva Port (Navi Mumbai), Mormugão Port (Goa), New Mangalore Port and Kochi Port in India, the Port of Karachi, Port Qasim, and the Gwadar Port in Pakistan, Chabahar Port in Iran and the Port of Salalah in Salalah, Oman. The largest islands in the Arabian Sea include Socotra (Yemen), Masirah Island (Oman), Lakshadweep (India) and Astola Island (Pakistan).
The Arabian Sea's surface area is about 3,862,000 km2 (1,491,130 sq mi). The maximum width of the Sea is approximately 2,400 km (1,490 mi), and its maximum depth is 4,652 metres (15,262 ft). The biggest river flowing into the Sea is the Indus River.
The Arabian Sea has two important branches — the Gulf of Aden in the southwest, connecting with the Red Sea through the strait of Bab-el-Mandeb; and the Gulf of Oman to the northwest, connecting with the Persian Gulf. There are also the gulfs of Khambhat and Kutch on the Indian Coast.
The countries with coastlines on the Arabian Sea are Yemen, Oman, Pakistan, Iran, India and the Maldives.
The International Hydrographic Organization defines the limits of the Arabian Sea as follows:
The Arabian sea was called Erythraean Sea in Roman times.
The Arabian Sea historically and geographically has been referred to with many different names by Arabian and European geographers and travelers, including Sindhu Sagar,Arabbi Samudra, and the Erythraean Sea,
The Arabian Sea has been an important marine trade route since the era of the coastal sailing vessels from possibly as early as the 3rd millennium BCE, certainly the late 2nd millennium BCE through the later days known as the Age of Sail. By the time of Julius Caesar, several well-established combined land-sea trade routes depended upon water transport through the Sea around the rough inland terrain features to its north.
These routes usually began in the Far East or down river from Madhya Pradesh with transshipment via historic Bharuch (Bharakuccha), traversed past the inhospitable coast of today's Iran then split around Hadhramaut into two streams north into the Gulf of Aden and thence into the Levant, or south into Alexandria via Red Sea ports such as Axum. Each major route involved transhipping to pack animal caravan, travel through desert country and risk of bandits and extortionate tolls by local potentates.
This southern coastal route past the rough country in the southern Arabian Peninsula was significant, and the Egyptian Pharaohs built several shallow canals to service the trade, one more or less along the route of today's Suez canal, and another from the Red Sea to the Nile River, both shallow works that were swallowed up by huge sand storms in antiquity. Later the kingdom of Axum arose in Ethiopia to rule a mercantile empire rooted in the trade with Europe via Alexandria.
The Port of Karachi is Pakistan's largest and busiest seaport. It is located between the Karachi towns of Kiamari and Saddar.
The Gwadar Port is a warm-water, deep-sea port situated at Gwadar in Balochistan, Pakistan at the apex of the Arabian Sea and at the entrance of the Persian Gulf, about 460 km west of Karachi and approximately 75 km (47 mi) east of Pakistan's border with Iran. The port is located on the eastern bay of a natural hammerhead-shaped peninsula jutting out into the Arabian Sea from the coastline.
Port of Salalah in Salalah, Oman is also a major port in the area. The International Task Force often uses the port as a base. There is a significant number of warships of all nations coming in and out of the port, which makes it a very safe bubble. The port handled just under 3.5m teu (twenty-foot equivalent unit, a measure used for capacity in container transportation) in 2009.
Jawaharlal Nehru Port in Mumbai is the largest port in the Arabian Sea, and the largest container port in India. Major Indian ports in the Arabian Sea are Mundra Port, Kandla Port, Nava Sheva, Kochi Port, Mumbai Port, and Mormugão.
There are several islands in the Arabian Sea, with the most important ones being Lakshadweep Islands (India), Socotra (Yemen), Masirah (Oman) and Astola Island (Pakistan).
The Lakshadweep Islands (formerly known as the Laccadive, Minicoy, and Aminidivi Islands) is a group of islands in the Laccadive Sea region of Arabian Sea, 200 to 440 km (120 to 270 mi) off the southwestern coast of India.

The Gulf of Aden is a deepwater gulf amidst Yemen to the north, the Arabian Sea to the east, Djibouti to the west, and the Guardafui Channel, Socotra (Yemen), Somaliland and Somalia to the south. In the northwest, it connects with the Red Sea through the Bab-el-Mandeb strait, and in the southeast, it connects with the Somali Sea segment of the Indian Ocean through the Guardafui Channel. To the west, it narrows into the Gulf of Tadjoura, in the Horn of Africa. The Gulf of Aden separates the Arabian peninsula with the Horn of Africa.
Gwadar is a port city on the southwestern coast of Balochistan, Pakistan. The city is located on the shores of the Arabian Sea opposite Oman. Gwadar was an overseas possession of Oman from 1783 to 1958. It is about 120 kilometres (75 mi) southwest of Turbat, while the sister port city of Chabahar in Iran's Sistan and Baluchestan Province is about 170 kilometres (110 mi) to the west of Gwadar.
Socotra or Soqotra, located between the Guardafui Channel and the Arabian Sea, is the largest of four islands in the Socotra archipelago. The territory is located near major shipping routes and is officially part of Yemen, and had long been a subdivision of the Aden Governorate. In 2004, it became attached to the Hadhramaut Governorate, which is much closer to the island than Aden. In 2013, the archipelago became its governorate, the Socotra Governorate.
The Laccadive Sea or lakshadweep Sea or ലക്ഷദ്വീപ് കടല് is a body of water bordering India, the Maldives, and Sri Lanka. It is located to the southwest of Karnataka, to the west of Kerala and to the south of Tamil Nadu. This warm sea has a stable water temperature through the year and is rich in marine life, the Gulf of Mannar alone hosting about 3,600 species. Mangaluru,Kannur, Kozhikode, Kochi, Kollam, Thiruvananthapuram, Tuticorin, Colombo, and Malé are the major cities on the shore of the Laccadive Sea. Kanyakumari, the southernmost tip of peninsular India, also borders this sea.

Lakshadweep, is a group of islands in the Laccadive Sea, 200 to 440 km off the southwestern coast of India. The archipelago is administered as a union territory and district of India. They were also known as Laccadive Islands, although geographically this is only the name of the central subgroup of the group. Lakshadweep means "one hundred thousand islands" in Malayalam. The islands form the smallest Union Territory of India and their total surface area is just 32 km2 (12 sq mi). The lagoon area covers about 4,200 km2 (1,600 sq mi), the territorial waters area 20,000 km2 (7,700 sq mi) and the exclusive economic zone area 400,000 km2 (150,000 sq mi). The region forms a single Indian district with 10 subdivisions. Kavaratti serves as the capital of the Union Territory and the region comes under the jurisdiction of Kerala High Court. The islands are the northernmost of the Lakshadweep-Maldives-Chagos group of islands, which are the tops of a vast undersea mountain range, the Chagos-Laccadive Ridge.

The years before 1975 featured the pre-1975 North Indian Ocean cyclone seasons. Each season was an ongoing event in the annual cycle of tropical cyclone formation. The North Indian tropical cyclone season has no bounds, but they tend to form between April and December, peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. Below are the most significant cyclones in the time period. Because much of the North Indian coastline is near sea level and prone to flooding, these cyclones can easily kill many with storm surge and flooding. These cyclones are among the deadliest on earth in terms of numbers killed.
Pasni, is a medium-sized city and a fishing port in Gwadar District, Balochistan, Pakistan. Its population is around 33,000. It is located on the Makran coast on Arabian Sea about 450 km from Karachi.

Super Cyclonic Storm Gonu was an extremely powerful tropical cyclone that became the strongest cyclone on record in the Arabian Sea. The second named tropical cyclone of the 2007 North Indian Ocean cyclone season, Gonu developed from a persistent area of convection in the eastern Arabian Sea on June 1, 2007. With a favorable upper-level environment and warm sea surface temperatures, it rapidly intensified to attain peak winds of 240 km/h (150 mph) on June 4, according to the India Meteorological Department. Gonu weakened after encountering dry air and cooler waters, and early on June 6, it made landfall on the easternmost tip of Oman, becoming the strongest tropical cyclone to hit the Arabian Peninsula. It then turned northward into the Gulf of Oman, and dissipated on June 7, after making landfall in southern Iran, the first landfall in the country since 1898.
The sooty gull is a species of gull in the family Laridae, also known as the Aden gull or Hemprich's gull. It is found in Bahrain, Djibouti, Egypt, Eritrea, India, Iran, Israel, Jordan, Kenya, Lebanon, Maldives, Mozambique, Oman, Pakistan, Qatar, Saudi Arabia, Somalia, Sri Lanka, Sudan, Tanzania, United Arab Emirates, and Yemen. As is the case with many gulls, it has traditionally been placed in the genus Larus. The sooty gull is named in honour of the German naturalist Wilhelm Hemprich who died in 1825 while on a scientific expedition to Egypt and the Middle East with his friend Christian Gottfried Ehrenberg.
The Arabian Peninsula coastal fog desert, also known as the Southwestern Arabian coastal xeric scrub, is desert ecoregion on the southern coasts of the Arabian Peninsula, which experiences thick fogs where visibility may be reduced to 33 feet (10 m). It is classed as an Afrotropical fog desert
Very Severe Cyclonic Storm Phet was a powerful tropical cyclone that made landfall on Oman, Western India, and Pakistan. The third named cyclone of the 2010 cyclone season, Phet developed in the Arabian Sea on May 31 to the west of India. With conducive environmental conditions, the storm intensified to reach peak sustained winds of 155 km/h (100 mph) on June 2, based on analysis by the India Meteorological Department (IMD). On the next day, Phet dropped heavy rainfall while moving across eastern Oman, with a peak of 603 mm (23.7 in) in Qurayyat. The rains flooded arid areas and collected into wadis – normally dry river beds. Thousands of homes were wrecked across Oman. There were 24 fatalities in the country, and damage was estimated at US$780 million.
The 1977 Oman cyclone was the deadliest tropical cyclone on record to strike Oman. The storm formed off the west coast of India in the Arabian Sea, and curved westward to reach peak winds of 110 km/h (70 mph). The storm struck Masirah Island and later southern Oman on June 13, before dissipating the next day over Saudi Arabia. Producing wind gusts to 230 km/h (140 mph), the storm was the strongest cyclone on record to hit the Arabian Peninsula until Cyclone Gonu hit in 2007. About 95% of Marisah Island was damaged by the strong winds, including much of the military base. The cyclone dropped 430.6 mm (16.95 in) of rainfall over a 24 hour period on Marisah, which was the highest daily total in the country as of 2003. Overall, the storm killed at least 105 people and left 50,000 homeless.
Extremely Severe Cyclonic Storm Mekunu was the strongest storm to strike Oman's Dhofar Governorate since 1959. The second named storm of the 2018 North Indian Ocean cyclone season, Mekunu developed out of a low pressure area on May 21. It gradually intensified, passing east of Socotra on May 23 as a very intense tropical cyclone. On May 25, Mekunu reached its peak intensity. The India Meteorological Department estimated 10 minute sustained winds of 175 km/h (110 mph), making Mekunu an extremely severe cyclonic storm. The American-based Joint Typhoon Warning Center estimated slightly higher 1 minute winds of 185 km/h (115 mph). While at peak intensity, Mekunu made landfall near Raysut, Oman, on May 25. The storm rapidly weakened over land, dissipating on May 27.
