The city-state enjoys a year-round summer season with average temperatures of 31 ̊C / 88 ̊F during the day and 24 ̊C / 75 ̊F in the evening. Although there are no specific dry and wet seasons, Singapore has two distinct monsoon seasons from December to March and June to September. Being part of the tropical climate, expect high humidity and short bursts of rainfall during non-monsoon periods of time.
A Goods & Services Tax (GST) is payable for most purchases made in Singapore, which is similar to the Value Added Tax (VAT) in many other countries. As a tourist in Singapore, if you make any purchase of more than S$100 (including GST) at participating shops, you may claim a refund on the 7% Goods & Services Tax (GST) paid on your purchases.

Tipping is not customary in Singapore and most service providers such as restaurants and hotels charge a 10% service charge. That said, it is more than welcome to reward exceptional customer service with a courtesy gratuity.
