Due to Singapore's geographical location, its climate is characterised by uniform temperature and pressure, high humidity and abundant rainfall. Rainfall maximum occurs in December and April while the drier months are usually February and July. Daily temperatures range from 23°C to 34°C. With a population of 5.4 million, Singapore is one of the most densely populated countries in the world.
As a small low-lying island city state of 716km2 situated in the tropics, Singapore is vulnerable to the impacts of climate change. For instance, sea level rise poses a threat to Singapore as much of the island is less than 15m above sea level, with a generally flat coast. The neighbouring countries have already experienced increasingly intense storms and tropical cyclones, flooding and prolonged droughts in recent years. Rises in sea level and ambient temperature have already been observed for Singapore.
