Central Singapore
Hougang weather
Northeast heartland. Typical inland convection on hot, still afternoons.
How rain usually arrives here
Hougang behaves like the other northeast heartland towns: inland heating, afternoon thunderstorms in the inter-monsoon, and a weaker signal from west-origin squalls. Pair the nowcast with Sengkang and Punggol, which often match it.
After lunch in April, May, October and November, use the 2-hour nowcast and the 50 km radar together. The island 24-hour line is too coarse.
Central Singapore
Central towns sit on the inland heating plateau and against the catchment. Inter-monsoon afternoons are thunderstorm country. A stalled red cell over Toa Payoh or Bishan is the usual flash-flood setup.
