Geography of Singapore
Singapore is a small, heavily urbanised, island, city-state in Southeast Asia, located at the end of the Malayan Peninsula between Malaysia and Indonesia. Singapore has a total land area of Script error: No such module "convert"..
The Singapore area comprises mainland and other islands. The mainland of Singapore measures Script error: No such module "convert". from east to west and Script error: No such module "convert". from north to south with Script error: No such module "convert". of coastline. These figures are based on Script error: No such module "convert". High Water Mark cadastral survey boundaries.
Singapore's main territory is a diamond-shaped island, although its territory includes surrounding smaller islands. The farthest outlying island is Pedra Branca. Singapore is slightly more than 3.5 times the size of Washington, D.C. Of Singapore's dozens of smaller islands, Jurong Island, Pulau Tekong, Pulau Ubin and Sentosa are the larger ones. Most of Singapore is no more than 15 meters above sea level.
The highest point of Singapore is Bukit Timah, with a height of 165 m (538 ft) and made up of igneous rock, granite. Hills and valleys of sedimentary rock dominate the northwest, while the eastern region consists of sandy and flatter land. Singapore has no natural lakes, but reservoirs and water catchment areas have been constructed to store fresh water for Singapore's water supply.
Singapore has reclaimed land with earth obtained from its own hills, the seabed, and neighbouring countries. As a result, Singapore's land area has grown from 581.5 km² in the 1960s to 723.2 km² today, and may grow by another 100 km² by 2033.
Climate of Singapore
Singapore is 1 degree north of the equator. Singapore's climate is classified as tropical rainforest climate (Köppen climate classification Af), with no true distinct seasons. Owing to its geographical location and maritime exposure, its climate is characterized by uniform temperature and pressure, high humidity and abundant rainfall. So it is almost always warm and wet. The average annual rainfall is around Script error: No such module "convert".. The highest 24-hour rainfall figures ever recorded in history were Script error: No such module "convert". (1978), Script error: No such module "convert". (1969) and Script error: No such module "convert". (19 December 2006).
The temperature hovers around a diurnal range of a minimum of Script error: No such module "convert". and a maximum of Script error: No such module "convert".. May is the hottest month of the year in Singapore, followed by April. This is due to light winds and strong sunshine during those months. The highest recorded temperature is Script error: No such module "convert". on 26 March 1998. The lowest recorded temperature was Script error: No such module "convert". in January 1934. Temperature often goes above Script error: No such module "convert". and can reach Script error: No such module "convert". at times.
Relative humidity has a diurnal range in the high 90s in the early morning to around 60% in the mid-afternoon, but does go below 50% at times. In May 2009, the average relative humidity was 81%, an increase over the figure of 77.1% in May 2008. During prolonged heavy rain, relative humidity often reaches 100%. Generally, there is much more rainfall on the western side of the island than on the eastern portion of Singapore, owing to a rain shadow effect.
Thus, the eastern side of Singapore is much drier and slightly hotter than western Singapore. This can cause slight weather disparities from one side of the island to the other. This is significant to note because even a small hill such as Bukit Timah can cause this phenomenon. Despite Singapore's small size, there may be sunshine on one side while there is rain on the other.
Further contrasts that prevent true all-year uniformity are the monsoon seasons which happen twice each year. The first one is the Northeast Monsoon which occurs from mid-November to early March. The second is the Southwest Monsoon season which occurs from June to September. Periods between monsoon seasons receive less rain and wind. During the Northeast Monsoon, northeast winds prevail, sometimes reaching Script error: No such module "convert".. There are cloudy conditions in December and January with frequent afternoon showers.
Spells of widespread moderate to heavy rain occur lasting from 1 to 3 days at a stretch. It is relatively dry in February till early March although rainfall still exceeds 120mm. It is also generally windy with wind speeds sometimes reaching Script error: No such module "convert". in the months of January and February. During the Southwest Monsoon season, southeast winds prevail. Isolated to scattered showers occur in the late morning and early afternoon. Early morning "Sumatra" squall lines are common.

|Climate chart (explanation)|
Singapore is relatively safe from seismic activity in the region, as the nearest major active faults (Sumatran fault and Sunda megathrust fault) are hundreds of kilometres away in Indonesia. However, the population and buildings are prone to being only very slightly affected by any activity as tremors, which is not uncommon, but generally does not do any harm and is limited to small amounts of swaying or vibration of objects.
In late 2004, several parts of Asia and Africa were struck by the 2004 Indian Ocean earthquake and the resulting tsunami. Singapore was fortunate as it was protected by the Sumatra landmass, which bore the brunt of the tsunami; the effect on Singapore was limited to tremors felt in some of the common high-rise buildings there.
Igneous rocks are found in Bukit Timah and Woodlands and Pulau Ubin island. Granite makes up the bulk of the igneous rock. Gabbro is also found in the area and is found in an area called Little Guilin named for its resemblance to Guilin in Southern China.This area is in Bukit Gombak. Sedimentary rocks are found on the western part of Singapore and is mainly made of sandstone and mudstones. It also includes the southwestern area. Metamorphic rocks are found in the northeastern part of Singapore and also on Pulau Tekong off the east coast of Singapore. The rocks are mainly made up of quartzite and also make up the Sajahat Formation.
Political and human geography
When Singapore was first colonized by the British, the city of Singapore was situated on the southern coast, around the mouth of the Singapore River. This area remains the Downtown Core of Singapore. The rest of the island was farmland and primary rainforest. However, since the 1960s the government has constructed many new towns in other areas, so that today the island is nearly entirely built-up and urbanised, with only a few exceptions, such as Bukit Timah Nature Reserve or reclaimed land in the process of being developed. However, even though Singapore is nearly totally urban, the Central Area, which contains a high concentration of financial and commercial districts because this area is closest to Singapore's port.
The Urban Redevelopment Authority is the government agency responsible for the urban planning of Singapore, which seeks to implement efficient land use, minimise pollution while maintaining convenient transport, which are Singapore's largest concerns because of its situation as a city-state. A Development Guide Plan has been released in the process.
In order to reduce traffic congestion, Electronic road pricing (ERP) has been enacted around entrances into the Central Area. The other parts of Singapore are less dense and busy, and are often filled with housing estates such as from the Housing and Development Board (HDB) or condominiums, and commercial districts are less concentrated. However, to reduce strain on the Central Area, several regional centres have been developed, each containing a concentrated commercial district.
Light industry tends to be distributed around the island as industrial estates and located in flats, similar to the HDB, and only allow tenants which produce close to nil pollution, whereas heavy industry tends to be located around Jurong and Jurong Island. A list of such estates can be found here.
There are two connections to the state of Johor, Malaysia. In the north there is a causeway for both rail and road traffic, which connects to the city of Johor Bahru. In the west there is a road bridge (Tuas Second Link), which connects to Johor, for road traffic only. The connections are an important economic link to Malaysia, which can be seen as a hinterland.
The causeway (1,038 m in length) was designed by Coode, Fizmaurice, Wilson and Mitchell of Westminster and constructed by Topham, Jones & Railton Ltd of London. It was started in 1909 as a railway link by Johor State Railway to connect Johor Bahru to Singapore, then the administrative headquarters of British interests in Southeast Asia. Construction of the road section started in 1919 and completed in 1923.
The causeway has caused ecological problems, most notably accumulation of silt in the Johore Strait. This has led to disagreements with Malaysia. Singapore has rejected Malaysia's proposal to replace the causeway with a bridge, and Malaysia has since proposed the idea of what became known as "the crooked half-bridge", descending halfway to link up with the low-level causeway.
Since Singapore lacks natural freshwater rivers and lakes, the primary source of domestic water is rainfall. Demand for fresh water is approximately twice that supplied by rainfall, so Singapore imports much of its fresh water from Malaysia and Indonesia. To lessen its reliance on imports, Singapore has built reservoirs to collect rainwater and recycled water facilities. In addition, Singapore has built a desalination plant on the western coast of Tuas. This plant is expected to at least meet half of Singapore's water demands. Recent plans to produce NEWater-recycled water from treatment by filtration via reverse osmosis have been very successful as the government has opened up three plants around the island to help meet the demand.
There are more than 300 parks and 4 nature reserves in Singapore. There are also many trees planted, and almost fifty per cent of the country is covered by greenery. Because of this, Singapore is also commonly known as the 'Garden City'.
