Exploring Bahrain's Climate: A Dry, Arid Region

Bahrain is an archipelago in the Middle East, located in the Persian Gulf. It is comprised of around 30 islands, including the largest, Bahrain Island. The country has a desert environment, with a hot, arid climate. Bahrain receives little precipitation, with average annual rainfall being confined to the winter months. The summer months are extremely hot, with temperatures averaging 40°C, while the winter months are relatively mild, with temperatures ranging from 10°C to 20°C. The combination of high temperatures and low rainfall makes Bahrain a dry region.

Bahrain's arid climate

Bahrain is an archipelago in the Middle East, located in the Persian Gulf. It is comprised of around 30 islands, including the largest, Bahrain Island. The country's climate is arid, with a very warm and humid climate.

Bahrain has two seasons: an extremely hot summer and a relatively mild winter. During the summer months, from April to October, afternoon temperatures average 40 °C (104 °F) and can reach 46 °C (114.8 °F) in May, June and July. The combination of intense heat and high humidity makes this season uncomfortable. In addition, a hot, dry southwest wind, known locally as the qaws, periodically blows sand clouds across the barren southern end of Bahrain toward the capital, Manama, in the summer.

Temperatures moderate in the winter months, from November to March, when the range is between 10 and 20 °C (50 and 68 °F). However, humidity often rises above 90% in the winter. From December to March, prevailing winds from the northwest, known as the shamal, bring damp air over the islands.

Bahrain receives little precipitation. The average annual rainfall is 72 millimetres (2.8 inches), usually confined to the winter months. No permanent rivers or streams exist on any of the islands. The winter rains tend to fall in brief, torrential downpours, flooding the shallow wadis that are dry the rest of the year and impeding transportation. Little of the rainwater is saved for irrigation or drinking.

Much of Bahrain is a rocky desert environment and quite barren of life aside from various desert plants, but some portions are irrigated and thus support some animals such as lizards, gazelles and migratory birds. Precipitation from the Saudi Arabian mountains provides support for some water springs and wells which produce rich water. Coastal salt marshes along some of the outer banks are not uncommon.

The highest point of the country is an escarpment named Jabal ad Dukham, which reaches 122 metres (400 feet) above sea level. This is also where most of the country's oil wells are found.

Bahrain is well known for its large growth of date palms, which thrive in the extremely humid and warm climate of this country. Temperatures are often in the 90s through the summer and the northwesterly wind is usually predominant, keeping the area humid. Rainfall is generally limited to the winter and although it can vary greatly, averages about three inches a year.

Water scarcity in Bahrain

Bahrain is an archipelago of more than 36 islands, shoals, and small islets located in the Persian Gulf, with a predominantly arid climate. The country experiences extremely hot summers and mild winters, with little rainfall throughout the year. This lack of precipitation, combined with increasing water demand, has led to a water scarcity issue in Bahrain, making it one of the top ten countries likely to suffer from a water crisis in the next 25 years.

Water Sources

Bahrain has limited renewable groundwater resources, with only 3 cubic meters of renewable groundwater per capita, compared to a world average of 6,000 cubic meters. The country relies mainly on groundwater and desalinated seawater to meet its water needs. Historically, Bahrain utilized groundwater for agricultural and municipal requirements, but with the discovery of offshore reservoirs of crude oil and gas in 1946, water demand increased, leading to a decline in spring flow. Today, about 60% of daily water consumption needs are met by desalinated seawater, while the rest is sourced from primary groundwater and treated sewage effluent.

Challenges and Impacts

The increasing population and high consumption patterns have led to the gradual depletion of groundwater sources in Bahrain. Over-extraction of groundwater has resulted in severe degradation of both the quality and quantity of water reserves, with seawater intrusion and saline water up-flow from deeper zones affecting more than half of the original groundwater reservoir. Additionally, the construction of numerous desalination plants has led to adverse environmental impacts, including increased carbon dioxide emissions, which contribute to climate change.

Strategies and Conservation Efforts

To address the water scarcity issue, the Bahraini government has implemented several strategies and promoted water conservation practices. The Water Resources Council (WRC) was formed in 1982 to protect and develop water resources and raise community awareness about optimal water usage. The WRC is responsible for drawing up the country's water policies, regulating water utilization, and coordinating between competing sectors.

Additionally, the government has plans for the full utilization of Treated Sewage Effluent (TSE) water through major agricultural projects, although delays and lack of funds have limited the use of these waters. The public has also been encouraged to adopt basic water conservation practices, such as turning off taps when not in use, using water-efficient appliances, and repairing water leaks promptly.

The impact of climate change on Bahrain

Bahrain is an archipelago of more than 36 islands in the Persian Gulf, with a predominantly arid climate. The country experiences extremely hot summers and mild winters, with little rainfall.

As a result of climate change, Bahrain faces a range of environmental challenges. With 81% of the population living in the capital city of Manama, which is located on the coast, one of the main issues is the threat of rising sea levels. By 2100, between 27% and 56% of the kingdom's area could be lost due to a rise in sea levels, according to different scenarios set out by the Intergovernmental Panel on Climate Change.

To address these challenges, Bahrain has implemented several mitigation measures. These include strengthening coastal monitoring, integrating enhanced environmental safeguards, and raising awareness among policymakers and the public about the impacts of rising sea levels. The kingdom has also focused on rehabilitating mangroves, establishing conservation zones for coral reefs, and intensifying afforestation efforts to protect its marine ecosystems.

Bahrain's desert landscape

Bahrain is a generally flat and arid archipelago in the Persian Gulf, comprising a small archipelago of more than 36 islands, shoals, and small islets. The main island of Bahrain accounts for about 85% of the total area and is largely desert, except for a narrow fertile strip along the northern and northwestern coastlines.

The desert landscape is characterised by low-lying barren land, with outcroppings of limestone forming low rolling hills, stubby cliffs, and shallow ravines. The limestone is covered by various densities of saline sand, capable of supporting only the most hardy desert vegetation, chiefly thorn trees and scrub. The interior contains an escarpment that rises to 134 meters, forming Jabal al Dukhan (Mountain of Smoke), named for the mists that often wreathe the summit. Most of the country's oil wells are located near Jabal al Dukhan.

Bahrain's desert environment is home to many types of insects, reptiles, birds, and wild mammals. The country also features important marine habitats, including mangrove and seagrass beds in the intertidal regions and coral reefs in the sub-tidal regions.

The country experiences periodic droughts and dust storms, and faces environmental challenges such as desertification, coastal degradation, and water scarcity.

The Persian Gulf's influence on Bahrain's climate

Bahrain is an archipelago of over 30 islands located in the Persian Gulf, off the north shore of the Arabian Peninsula. The Persian Gulf is a mediterranean sea, an extension of the Indian Ocean, located between Iran and the Arabian Peninsula. It is connected to the Gulf of Oman in the east by the Strait of Hormuz. The climate of the Persian Gulf is known to be unfavourable, with extreme temperatures throughout the year. Winters may be cool, especially in the extreme northwestern regions, and precipitation is sparse. The region experiences more cloud cover in winter than in summer, and haze and dust storms are common during the colder months.

The Persian Gulf's high temperatures, low freshwater inflow, and shallow waters result in a high freshwater evaporation rate. The salinity of the gulf ranges from 37 to 41 parts per 1000. The surface water temperature varies from 60 to 90 degrees Fahrenheit in the northwest to 75 to 90 degrees Fahrenheit in the Strait of Hormuz. The climate of Bahrain is arid, with a very hot summer and a relatively mild winter. During the summer months, from April to October, afternoon temperatures average 40 °C (104 °F) and can reach 46 °C (114.8 °F) in June and July. The combination of intense heat and high humidity makes this season uncomfortable.

The Persian Gulf's high evaporation rate and shallow waters also affect Bahrain's climate and environment. Bahrain's marine environment is characterised by high rates of evaporation during most of the year and a shortage of freshwater input. The country is highly water-stressed from a freshwater resource availability perspective, with only 3 cubic meters of renewable groundwater per capita, compared to a world average of 6,000 cubic meters per capita. The most pressing environmental concerns in Bahrain include desertification, droughts, and dust storms.

The climate and environment of Bahrain are closely linked to the Persian Gulf. The high temperatures and shallow waters of the gulf contribute to the arid climate and water stress in Bahrain. The gulf's isolation from international waters also makes the wildlife and flora unique and diverse, with Bahrain sharing some of the same environmental challenges.
