The Bahamas are a group of about 700 islands and cays in the western Atlantic Ocean, of which only between 30 and 40 are inhabited. The largest of the islands is Andros Island, located north of Cuba and 200 kilometres (120 miles) southeast of Florida. The Bimini islands are to its northwest. To the North is the island of Grand Bahama, home to the second-largest city in the country, Freeport. The island of Great Abaco is to its east. In the far south is the island of Great Inagua, the second-largest island in the country. Other notable islands include Eleuthera, Cat Island, San Salvador Island, Acklins, Crooked Island, and Mayaguana. Nassau is the capital and largest city, located on New Providence. The islands have a tropical savannah climate, moderated by the Gulf Stream. The total size is 13,878 km2 (5,358 sq mi). Due to the many widespread islands it has the 41st largest Exclusive Economic Zone of 654,715 km2 (252,787 sq mi).
The islands are surface projections of two oceanic Bahama Banks - the Little Bahama Bank and the Great Bahama Bank. [1] The highest point is only 63 metres (207 feet) above sea level on Cat Island; the island of New Providence, where the capital city of Nassau is located, reaches a maximum elevation of only thirty-seven meters. The land on the Bahamas has a foundation of fossil coral, but much of the rock is oolitic limestone; the stone is derived from the disintegration of coral reefs and seashells. [1] The land is primarily either rocky or mangrove swamp. [1] Low scrub covers much of the surface area. [1] Pineyards are found on four of the northern islands: Grand Bahama, Great Abaco, New Providence, and Andros. [1] On some of the southern islands, low-growing tropical hardwood flourishes. [1] Although some soil is very fertile, it is also very thin. [1] Only a few freshwater lakes and just one river, located on Andros Island, are found in the Bahamas. [1]

The climate of the Bahama islands is mostly tropical savanna, with two seasons, a hot and wet summer (wet season) and dry winter (dry season).
During the wet season, which extends from May through October, the climate is dominated by warm, moist tropical air masses [1] as the Bermuda High brings a southeasterly flow from the deep tropics. Daily high temperatures are in the 31 °C (87.8 °F) range, with a dew point temperatures in the 75–77 °F (23.9–25.0 °C) range, creating the typical hot and sultry island weather. Brief but intense thundershowers are common with thunder and lightning. In the wet season, tropical storms and weak tropical lows may also contribute to the seasonal rainfall.
In the dry season, extending from November through April, the subtropical high retreats, and a mix of drier northeast trade winds and occasional westerlies coming down from the North American mainland impact the Bahamas. Sunny, arid conditions prevail in the Bahamas in the dry season, and at times drought conditions can impact farming and agriculture. High temperatures during the dry season are in the 25 °C (77.0 °F) range.
Annual rainfall averages 132 centimetres (52 in) and is usually concentrated in the May–June and September–October periods. [1] Rainfall often occurs in short-lived, fairly intense, but brief thundershowers accompanied by strong gusty winds, followed by a return to clear skies. [1]
Winds are predominantly easterly throughout the year but tend to become northeasterly from October to April and southeasterly from May to September. [1] These winds seldom exceed twenty-four kilometres per hour except during hurricane season. [1] Although the hurricane season officially lasts from June to November, most hurricanes in the Bahamas occur between July and October. [1] The strongest storm to strike the country was Hurricane Andrew in 1992, until Hurricane Dorian struck in 2019. Damage was estimated at US$250 million and mainly affected agricultural products.
The most intense hurricane to strike the Bahamas was Hurricane Dorian in 2019, with wind gusts of up to 355 kilometres per hour (221 mph) being recorded. 84 people died (74 of which were from the Bahamas), and there was catastrophic damage to buildings, homes, and boats, and sometimes complete destruction. Preliminary damage estimates are in the US$7 billion range. [10]

Geographic coordinates (capital city Nassau): 25°4′N 77°20′W
As an island nation, The Bahamas is made up of numerous archipelagos, beaches, straits, blue holes, and other landforms. The tallest mountain is Mount Alvernia, at only 207 feet above sea level. Notable bodies of water include Dean's Blue Hole, Lake Rosa, and the Goose River. The Bahamas also contains many creeks.
Party to these agreements:
The Bahamas, officially the Commonwealth of The Bahamas, is an island country within the Lucayan Archipelago of the West Indies in the Atlantic Ocean. It contains 97% of the Lucayan Archipelago's land area and 88% of its population. The archipelagic state consists of more than 3,000 islands, cays, and islets in the Atlantic Ocean, and is located north of Cuba and northwest of the island of Hispaniola and the Turks and Caicos Islands, southeast of the U.S. state of Florida, and east of the Florida Keys. The capital is Nassau on the island of New Providence. The Royal Bahamas Defence Force describes The Bahamas' territory as encompassing 470,000 km2 (180,000 sq mi) of ocean space.
Andros Island is an archipelago within The Bahamas, the largest of the Bahamian Islands. Politically considered a single island, Andros in total has an area greater than all the other 700 Bahamian islands combined. The land area of Andros consists of hundreds of small islets and cays connected by mangrove estuaries and tidal swamplands, together with three major islands: North Andros, Mangrove Cay, and South Andros. The three main islands are separated by bights, estuaries that trifurcate the island from east to west. It is 167 kilometres (104 mi) long by 64 km (40 mi) wide at the widest point.
The Abaco Islands lie in the northern Bahamas, located about 193 miles east of Miami, Florida. The main islands are Great Abaco and Little Abaco, which is located just west of the northern tip of Great Abaco. There are several smaller barrier cays, of which the northernmost are Walker's Cay and its sister island Grand Cay. To the south, the next inhabited islands are Spanish Cay and Green Turtle Cay, with its settlement of New Plymouth, Great Guana Cay, private Scotland Cay, Man-O-War Cay, and Elbow Cay, with its settlement of Hope Town. Southernmost are Tilloo Cay and Lubbers Quarters. Another of note off Abaco's western shore is Gorda Cay, now a Disney-owned island and a cruise ship stop renamed Castaway Cay. Also in the vicinity is Moore's Island. On the Big Island of Abaco is Marsh Harbour, the Abacos' commercial hub and the Bahamas' third largest city, plus the resort area of Treasure Cay. Both have airports. A few mainland settlements of significance are Coopers Town and Fox Town in the north and Cherokee and Sandy Point in the south. Administratively, the Abaco Islands constitute seven of the 31 Local Government Districts of the Bahamas: Grand Cay, North Abaco, Green Turtle Cay, Central Abaco, South Abaco, Moore's Island, and Hope Town.
Hurricane Jeanne was a Category 3 hurricane that struck the Caribbean and the Eastern United States in September 2004. It was the deadliest hurricane in the Atlantic basin since Mitch in 1998. It was the tenth named storm, the seventh hurricane, and the fifth major hurricane of the season, as well as the third hurricane and fourth named storm of the season to make landfall in Florida. After wreaking havoc on Hispaniola, Jeanne struggled to reorganize, eventually strengthening and performing a complete loop over the open Atlantic. It headed westwards, strengthening into a Category 3 hurricane and passing over the islands of Great Abaco and Grand Bahama in the Bahamas on September 25. Jeanne made landfall later in the day in Florida just two miles from where Hurricane Frances had struck a mere three weeks earlier.
The 1926 Nassau hurricane also known as the San Liborio hurricane or The Great Bahamas Hurricane of 1926, in Puerto Rico, was a destructive Category 4 hurricane that affected the Bahamas at peak intensity. Although it weakened considerably before its Florida landfall, it was one of the most severe storms to affect the Bahamian capital Nassau and the island of New Providence in several years until the 1928 Okeechobee hurricane, which occurred just two years later. The storm also delivered flooding rains and loss of crops to the southeastern United States and Florida. Being a slightly mid-range Category 4, this hurricane peaked at about 967 mbars, making it the least intense Category 4 Atlantic hurricane on record, especially for wind speeds of 140 mph.
The 1929 Bahamas hurricane was a high-end Category 4 tropical cyclone whose intensity and slow forward speed led to catastrophic damage in the Bahamas in September 1929, particularly on Andros and New Providence islands. Its erratic path and a lack of nearby weather observations made the hurricane difficult to locate and forecast. The storm later made two landfalls in Florida, killing eleven but causing comparatively light damage. Moisture from the storm led to extensive flooding over the Southeastern United States, particularly along the Savannah River. Across its path from the Bahamas to the mouth of the Saint Lawrence River, the hurricane killed 155 people.
The 1932 Bahamas hurricane, also known as the Great Abaco hurricane of 1932, was a large and powerful Category 5 hurricane that struck the Bahamas at peak intensity. The fourth tropical storm and third hurricane in the 1932 Atlantic hurricane season, it was also one of two Category 5 hurricanes in the Atlantic Ocean that year, the other being the 1932 Cuba hurricane. The 1932 Bahamas hurricane originated north of the Virgin Islands, became a strong hurricane, and passed over the northern Bahamas before recurving. The storm never made landfall on the continental United States, but its effects were felt in the northeast part of the country and in the Bahamas, especially on the Abaco Islands, where damage was very great. To date, it is one of four Category 5 Atlantic hurricanes to make landfall in the Bahamas at that intensity, the others having occurred in 1933, 1992, and 2019.
Hurricane Able was a rare hurricane that formed outside the typical North Atlantic hurricane season. The second tropical storm and first hurricane of 1951, Able developed from a trough of low pressure on May 15 about 300 miles (480 km) south of Bermuda. Initially subtropical in nature, Able acquired tropical characteristics as it moved over the warm waters of the Gulf Stream and attained hurricane status on May 17 off the coast of Florida. This made Able one of only four May Atlantic hurricanes on record. On May 22 Able reached peak winds of 90 mph (140 km/h) about 70 miles (110 km) off Cape Hatteras, North Carolina. The hurricane weakened as it turned eastward, and became an extratropical cyclone on May 23, before dissipating on the next day.
The effects of Hurricane Wilma in The Bahamas were generally unexpected and primarily concentrated on the western portion of Grand Bahama. Hurricane Wilma developed on October 15, 2005 in the Caribbean, and after initially organizing slowly it explosively deepened to reach peak winds of 185 mph (298 km/h) and a record-low pressure of 882 mbar (hPa). It weakened and struck eastern Mexico as a Category 4 hurricane on the Saffir–Simpson scale, and accelerated northeastward to make landfall on southwestern Florida on October 24. After crossing the state, Wilma briefly restrengthened in the open Atlantic Ocean, moving north of The Bahamas before weakening and later becoming an extratropical cyclone.
The effects of Hurricane Andrew in the Bahamas included three direct fatalities and $250 million (1992 USD) in damage. Forming from a tropical wave on August 16, Andrew remained weak until rapidly intensifying on August 22, and late on August 23 it made its first landfall in The Bahamas on Eleuthera as a Category 5 hurricane with winds of 260 km/h (160 mph); early the next day Hurricane Andrew passed through the southern Berry Islands with winds of 240 km/h (150 mph). The hurricane later made a devastating landfall in southern Florida, and after striking southern Louisiana it dissipated over the eastern United States. Andrew was the first major hurricane to affect the nation since Hurricane Betsy in 1965. It caused $250 million in damage, with damage heaviest on Eleuthera and Cat Cay. Four deaths occurred due to the storm, of which one was indirectly related to the hurricane.
The following outline is provided as an overview of and topical guide to The Bahamas:
Hurricane Fox was a powerful and destructive tropical cyclone that crossed central Cuba in October 1952. The seventh named storm, sixth hurricane, and third major hurricane of the 1952 Atlantic hurricane season, it was the strongest and deadliest system of the season. Fox developed northwest of Cartagena, Colombia, in the southern Caribbean Sea. It moved steadily northwest, intensifying to a tropical storm on October 21. The next day, it rapidly strengthened into a hurricane and turned north passing closely to Grand Cayman, Cayman Islands. The cyclone attained peak winds of 145 mph (233 km/h) as it struck Cayo Guano del Este off the coast of Cienfuegos. Fox made landfall on Cuba at maximum intensity, producing peak gusts of 170–180 mph (270–290 km/h). It weakened over land, but it re-strengthened as it turned east over the Bahamas. On October 26, it weakened and took an erratic path, dissipating west-southwest of Bermuda on October 28.
The following is an alphabetical list of topics related to the Commonwealth of The Bahamas.
The Bahamian pineyards are a tropical and subtropical coniferous forest ecoregion in the Bahamas and the Turks and Caicos Islands.
Tropical Storm Bret was the second named storm of the 2011 Atlantic hurricane season. Bret formed along the southwestern periphery of a weather front north of the Bahamas on July 17. At first, the storm moved little and gradually strengthened in response to favorable upper-level conditions, reaching peak sustained winds of 70 mph (110 km/h). Steering currents in the area subsequently became better established, and Bret turned toward the northeast only to encounter a substantial increase in vertical wind shear. Despite the shear, the storm maintained a well-defined wind circulation for several days, with intermittent bursts of thunderstorms near its center. By July 22, Bret had been devoid of strong thunderstorm activity for several hours, prompting the National Hurricane Center to discontinue public advisories when it was located about 375 miles (604 km) north of Bermuda.
Hurricane Dorian was an extremely powerful and catastrophic Category 5 Atlantic hurricane, which became the most intense tropical cyclone on record to strike the Bahamas, and is tied with the 1935 Labor Day hurricane for the strongest landfall in the Atlantic basin in terms of maximum sustained winds. The 2019 cyclone is regarded as the worst natural disaster in the Bahamas' recorded history. With winds peaking at 185 mph (295 km/h), it was also one of the most powerful hurricanes recorded in the Atlantic Ocean in terms of 1-minute sustained winds, and the strongest since Wilma in 2005. Dorian was the fourth named storm, second hurricane, the first major hurricane, and the first Category 5 hurricane of the 2019 Atlantic hurricane season. Dorian struck the Abaco Islands on September 1 with maximum sustained winds of 185 mph (295 km/h), tying with the 1935 Labor Day hurricane for the highest wind speeds of an Atlantic hurricane ever recorded at landfall. Dorian went on to strike Grand Bahama at similar intensity, stalling just north of the territory with unrelenting winds for at least 24 hours. The resultant damage to these islands was catastrophic; most structures were flattened or swept to sea, and at least 70,000 people were left homeless. After it ravaged through the Bahamas, Dorian proceeded along the coasts of the Southeastern United States and Atlantic Canada, leaving behind considerable damage and economic losses in those regions.
Hurricane Dorian was the strongest hurricane to affect The Bahamas on record, causing catastrophic damage on the islands of Abaco Islands and Grand Bahama, in early September 2019. The cyclone's intensity, as well as its slow forward motion near The Bahamas, broke numerous records. The fifth tropical cyclone, fourth named storm, second hurricane, and first major hurricane of the 2019 Atlantic hurricane season, Dorian originated from a westward-traveling tropical wave, that departed from the western coast of Africa on August 19. The system organized into a tropical depression and later a tropical storm, both on August 24.
The effects of Hurricane Dorian in the Bahamas in 2019 were among the worst experienced for any natural disaster in the country. Hurricane Dorian struck the Abaco Islands as a Category 5 hurricane on September 1, and a day later hit Grand Bahama Island at the same category. The hurricane then stalled over Grand Bahama for another day, finally pulling away from the island on September 3. Damage amounted to US$3.4 billion, and there were at least 74 deaths in the country. Another 282 people were left missing after the hurricane.
The Bahama Archipelago, also known as the Lucayan Archipelago, is an island group comprising the Commonwealth of The Bahamas and the British Overseas Territory of the Turks and Caicos Islands. The archipelago is in the western North Atlantic Ocean, north of Cuba along with the other Antilles, and east and southeast of Florida. The archipelago has experienced the effects of at least 22 Atlantic hurricanes, or storms that were once tropical or subtropical cyclones, including 17 since 2000. The storms collectively killed 101 people.
Hurricane Nicole was a sprawling late-season Category 1 hurricane in November 2022. The fourteenth named storm and eighth hurricane of the 2022 Atlantic hurricane season, Nicole formed as a subtropical cyclone on November 7, from a non-tropical area of low pressure near the Greater Antilles, and transitioned into a tropical cyclone the next day. Then, taking a path similar to that of Hurricane Dorian three years earlier, Nicole made landfall on November 9, on Great Abaco and on Grand Bahama in The Bahamas, where it strengthened into a Category 1 hurricane. On November 10, it made landfall twice in Florida, south of Vero Beach and then northwest of Cedar Key, after briefly emerging over the Gulf of Mexico. Nicole then weakened to a depression while moving over the Florida Panhandle, and then was absorbed into a mid-latitude trough and cold front over extreme eastern Tennessee the following day.
