Central Singapore
Punggol weather
Northeast waterfront town. Sea breeze from the Johor Strait can shape local storms.
How rain usually arrives here
The Punggol waterfront gets a Johor Strait sea breeze that can shape or delay afternoon storms. It often matches Sengkang on the nowcast. Northeast monsoon days feel windier here than in Toa Payoh.
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.
