Geography of the Bahamas

Geography of the Bahamas
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 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 . Due to the many widespread islands it has the 41st largest Exclusive Economic Zone of .
The islands are surface projections of two oceanic Bahama Banks - the Little Bahama Bank and the Great Bahama Bank. The highest point is only 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. The land is primarily either rocky or mangrove swamp. Low scrub covers much of the surface area. Pineyards are found on four of the northern islands: Grand Bahama, Great Abaco, New Providence, and Andros. On some of the southern islands, low-growing tropical hardwood flourishes. Although some soil is very fertile, it is also very thin. Only a few freshwater lakes and just one river, located on Andros Island, are found in the Bahamas.
Climate
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 as the Bermuda High brings a southeasterly flow from the deep tropics. Daily high temperatures are in the range, with a dew point temperatures in the 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 range.
Annual rainfall averages and is usually concentrated in the May–June and September–October periods. Rainfall often occurs in short-lived, fairly intense, but brief thundershowers accompanied by strong gusty winds, followed by a return to clear skies.
Winds are predominantly easterly throughout the year but tend to become northeasterly from October to April and southeasterly from May to September. These winds seldom exceed twenty-four kilometres per hour except during hurricane season. Although the hurricane season officially lasts from June to November, most hurricanes in the Bahamas occur between July and October. 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 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.
