Singapore Weather Guide: When Should You Visit?
Singapore sits at the southern tip of the Malay Peninsula, just above the equator, which gives the city-state a tropical monsoon climate with no distinct four seasons. Average annual temperatures hover around 26–27°C, and while it stays warm year-round, rainfall patterns shift between a wetter northeast monsoon and a drier southwest monsoon season.
This guide breaks down Singapore’s seasonal weather, month-by-month temperatures with practical clothing tips, the best time to visit, and key weather risks to prepare for.
