The mean daily maximum temperature for Central parts (Hulhule) of the Maldives is 30.5 degrees Celsius and minimum temperature is 25.7 degrees Celsius. On the other hand, mean daily maximum and minimum temperature for South (Gan) is 30.9 and 24.5 degree Celsius, respectively. Furthermore, mean daily maximum and minimum temperature for North (Hanimaadhoo) is 30.7 and 25.2 degrees Celsius, respectively. The highest temperature ever recorded in the Maldives was 36.8°C, recorded on 19 May 1991 at Kadhdhoo Meteorological Office. Likewise, the minimum temperature ever recorded in the Maldives was 17.2°C, recorded at the National Meteorological Centre on 11th April 1978. The wet season- southwest monsoon runs from mid-May to November. In this season Maldives experiences torrential rain. Central, Southern and Northern parts of the Maldives receive annual average rainfall of 1924.7mm, 2277.8mm, and 1786.4mm, respectively. The highest rainfall ever recorded in the Maldives with in 24 hour period was recorded on 9th July 2002 at Kaadedhdhoo Meteorological Office and amounts to 219.8mm of rainfall.
The fact that the Maldives is located at the equator, Maldives receives plentiful of sunshine through out the year. On average Southern atolls (Gan) of the Maldives receives 2704.07 hours of sunshine each year. Furthermore, on average central (Hulhule) parts of the country receives 2784.51 hours of sunshine per year.The Republic of Maldives is an island nation consisting of a group of atolls stretching south of India's Lakshadweep islands between the Minicoy and the Chargos archipelagoes, and about seven hundred kilometres (435 mi) south-west of Sri Lanka in the Laccadive Sea of Indian Ocean. The twenty-six atolls of Maldives encompass a territory featuring 1,192 islets, of which two hundred and fifty islands are inhabited.
The Maldives holds the record for being the lowest country in the world, with a maximum natural ground level of only 2.3 m (7½ ft) with the average being only 1.5 m above sea level, though in areas where construction exists this has been increased to several metres. Over the last century, sea levels have risen about 20 centimetres (8 in); further rises of the ocean could threaten the existence of Maldives. However, around 1970 the sea level there dropped 20-30 cm. In November of 2008, President Mohamed Nasheed announced plans to look into purchasing new land in India, Sri Lanka, and Australia, due to his concerns about global warming and the possibility of much of the islands being inundated with water from rising sea levels. Current estimates place sea level rise at 59 cm by the year 2100. The purchase of land will be made from a fund generated by tourism. The President has explained his intentions, saying "We do not want to leave the Maldives, but we also do not want to be climate refugees living in tents for decades".
A tsunami in the Indian Ocean caused by the 2004 Indian Ocean earthquake caused serious damage to the socioeconomic infrastructure which left many people homeless, and irreversible damage to the environment. After the disaster, cartographers are planning to redraw the maps of the islands due to alterations caused by the tsunami.
On April 22, 2008, then Maldives President Maumoon Abdul Gayoom pleaded for a cut in global greenhouse gas emissions, warning that rising sea levels could submerge the island nation of Maldives.
The reef is composed of coral debris and living coral. This acts as a natural barrier against the sea, forming lagoons. Other islands, set at a distance and parallel to the reef, have their own protective fringe of reef. An opening in the surrounding coral barrier allows access to the calmer lagoon waters.
The barrier reefs of the islands protect them from the storms and high waves of the Indian Ocean. The Indian Ocean has a great effect on the climate of the country by acting as a heat buffer, absorbing, storing, and slowly releasing the tropical heat. The heat is further mitigated by cool sea breezes.
A layer of humus 152-millimetre (6.0 in) -thick forms the top layer of soil on the islands. Below the humus layer are two feet of sandstone, followed by sand and then fresh water. Due to excessive salt in the soil near the beach, vegetation is limited there to a few plants such as shrubs, flowering plants, and small hedges. In the interior of the island, more vegetation such as mangrove and banyan grow. Coconut palms, the national tree, are able to grow almost everywhere on the islands and are integral to the lifestyle of the natives.
The limited vegetation is supplemented by the abundance of coral reefs and marine life.
Comparative studies of Maldivian oral, linguistic and cultural traditions and customs confirm that the first settlers were Dravidian people] from the nearest coasts, most probably fishermen from the southwest coasts of the modern Indian Subcontinent and the western shores of modern Sri Lanka during the early Chera period. There are some signs of Arab and east Asian inhabitants mostly in southernmost atolls. Over the centuries, the islands have been visited and their development influenced by sailors and traders from countries on the Arabian Sea and the Bay of Bengal. In 1953, there was a brief, abortive attempt to form a republic, but the sultanate was re-imposed. In 1959, objecting to Nasir's centralism, the inhabitants of the three southernmost atolls protested against the government. They formed the United Suvadive Republic and elected, Abdullah Afeef as president and Hithadhoo as capital of this republic. Although governed as an independent Islamic sultanate from 1153 to 1968, the Maldives was a British protectorate from 1887 until July 25, 1965.

The Maldivian ethnic identity is a blend of the cultures reflecting the peoples who settled on the islands, reinforced by religion and language. The earliest settlers were probably from southern India and Sri Lanka. They are linguistically and ethnically related to the people in the Indian subcontinent.
Some social stratification exists on the islands. It is not rigid, since rank is based on varied factors, including occupation, wealth, Islamic virtue, and family ties. Traditionally, instead of a complex caste system, like the Vedic one, there was merely a distinction between noble (bēfulhu) and common people in the Maldives. Members of the social elite are concentrated in Malé. Outside of the service industry, this is the only location where the foreign and domestic populations are likely to interact. The tourist resorts are not on islands where the natives live, and casual contacts between the two groups are discouraged.
A census has been recorded since 1905, which shows that the population of the country remained around 100,000 for the first seventy years of the last century. Following independence in 1965, the health status of the population improved so much that the population doubled by 1978, and the population growth rate peaked at 3.4% in 1985. By 2007, the population had reached 300,000, although the census in 2000 showed that the population growth rate had declined to 1.9%. Life expectancy at birth stood at 46 years in 1978, while it has now risen to 72 years. Infant mortality has declined from 127 per thousand in 1977 to 12 today, and adult literacy stands at 99%. Combined school enrollment stands in the high 90s.
As of April 2008, more than 70,000 foreign employees live in the country and another 33,000 illegal immigrants sums up more than one third of Maldivian population. They consist mainly of people from the neighbouring South Asian countries of India, Sri Lanka, Bangladesh and Nepal.
