Good to know
🏙️
The urban heat island effect is strong here
Dense high-rise development traps heat between streets and buildings, so the city can feel hotter and more oppressive at night than the raw temperature suggests.
🌬️
Wind is rare outside January to March
Aside from the sea breeze near the coast, noticeable wind is mostly limited to January, February, and March; for the rest of the year, heat and flat calm dominate.
🌫️
Regional haze can affect air quality
During the southwest monsoon, smoke and haze from forest fires on Sumatra can occasionally drift over Singapore, sometimes creating unhealthy air quality, generally until around mid-October.
⛈️
Sumatra squalls bring sudden pre-dawn storms
During the southwest monsoon, occasional thunderstorms with strong wind gusts, known as Sumatra squalls, can strike in the early morning hours.
🌀
Tropical cyclones are extremely rare this close to the Equator
Singapore's equatorial position normally shelters it from cyclones, though Tropical Storm Vamei formed nearby at the very end of 2001, an exceptionally rare event.
