Singapore weather by month

2006-2025, 20 years of records · Not a forecast

Singapore sits just north of the equator, so it is hot and humid year round with no real four seasons. What changes is the monsoon. The Northeast Monsoon runs from December to early March, with the most rain in December and early January, and February is the driest month. Late March to May and October to November are inter-monsoon periods with frequent afternoon thunderstorms. During the Southwest Monsoon, smoke haze from fires in Indonesia affects some years, mostly from late August into September. An umbrella is a year-round item.

Weighing daytime warmth against rain days, February came out as the easiest month. February was the quiet stretch with 6 rain days, against 17 in December.
