Currency: The Singapore unit of currency is the Singapore Dollar (SGD). Major cards are widely accepted by establishments in Singapore but an exchange rate and bank charges will apply.
Language: The Singapore government recognises four official languages: English, Malay, Mandarin, and Tamil. The national language is Malay, while English is mainly used as the business and working language. The colloquial patois spoken on the streets is a creole called Singlish amongst the locals, but is also known amongst academics in linguistics as Singapore Colloquial English.
Climate: Located just north of the equator, Singapore has a tropical climate and stays hot and humid throughout the year. Temperatures average around 31º C (88º F) during the day with little seasonal variation, although it’s slightly cooler in December and January, and hottest in April and May. Temperatures are unlikely to dip below 23º C (74º F) at night; the lowest temperature ever recorded was just over 19º C (66º F).
Singapore receives a considerable amount of rainfall – approximately 2340mm annually. Although there are no distinct wet or dry seasons, the region is affected by two different monsoons. The Northeast Monsoon generally takes place from December to March and is accompanied by more frequent rain, particularly from November to January.
Voltage: The standard voltage in Singapore is 220V/240V, 50 Hz. If you have equipment that runs on a higher voltage, you should not connect it to Singaporean power unless you have the correct transformer (voltage adaptor). Singapore uses the British BS1363 three-pronged square pin type socket.
