The Bahamian climate, mild throughout the year, is one of the great attractions of the area. The average temperature varies from the low 70s F (about 21 °C) during the winter to the low 80s F (about 27 °C) during the summer, and extremes seldom fall below the low 60s F (about 16 °C) or rise above the low 90s F (about 32 °C). The average annual rainfall is about 44 inches (1,120 mm), occurring mostly during the summer months. Prevailing winds, coming from the northeast in winter and from the southeast in summer, lend a cooling influence to a generally humid atmosphere. Tropical cyclones (hurricanes) pose a threat during the period from June to November and have occasionally caused great destruction.

Plant and animal life

Extensive and beautiful forests of Caribbean pine are found on Grand Bahama, Abaco, Andros, and New Providence islands. Hardwood forests also occur on some of the islands. Elsewhere the woody vegetation consists mostly of shrubs and low trees. Animal life is dominated by frogs, lizards, and snakes, all of them nonpoisonous, and several species of bats are found in caves along the more rocky coasts. Larger animals include the agouti, a rodent; the raccoon; the iguana; and the elegant flamingo, the national bird. All of these have been much reduced in numbers and in distribution. In addition, several animals—notably sheep, horses, and other livestock—have been introduced from Europe. The surrounding waters abound with fish and other edible marine animals, such as conch and spiny lobster (crayfish).

Ethnic groups, languages, and religion

Most of the population of The Bahamas is of African descent. There is a small but significant minority of mixed European and African heritage and a similar number of descendants of English pioneer settlers and loyalist refugees from the American Revolution. English is the only language native to Bahamians, although, because of the influx of Haitian immigrants since the mid-20th century, French or the related Haitian Creole vernacular is spoken. A high percentage of Bahamians are members of Christian churches; the majority of them are non-Anglican Protestants, with smaller proportions of Roman Catholics and Anglicans.

Settlement patterns and demographic trends

The centres of population are widely distributed on each island. Some are located leeward, where it is calm and sheltered—for example, Cat Island. Others face the north and northeastern sides, where they are exposed to the northeast trade winds—as in the case of the Abaco Cays (the cays off Abaco and Little Abaco islands). Main settlements usually occur where there is a natural harbour or at least accessibility for shipping. There has been a marked shift of population from fishing and farming villages to the centres of tourist and commercial activity. Most of the population movement has been to the islands of New Providence, Grand Bahama, and Abaco (Great Abaco). About two-thirds of the Bahamian population is concentrated on New Providence Island, which, with Grand Bahama and Abaco, has received the most internal migration.

The country’s rate of population increase is much higher than the Caribbean average, primarily because of immigration from the United States and other West Indian islands. The rate of natural population increase is about average for the Caribbean region, but both the birth and death rates are less than the average for the West Indies as a whole.
