Singapore in December

When to go

The Meteorological Service Singapore says the Northeast Monsoon begins in December, with an early wet phase when monsoon surges can bring widespread continuous rain, so check the World Meteorological Organization's December normals for temperature and precipitation before you plan outdoor days. Christmas Day is on the Ministry of Manpower's public holiday list, and the Singapore Tourism Board says Orchard Road is decked out with lights at Christmas, so check opening hours and busy areas around the holiday.
