Singapore is one of the wettest cities on Earth, averaging around 2,350 mm (about 93 inches) of rain a year with no true dry season, though the Northeast Monsoon from November to January and pre-monsoon squalls known locally as Sumatras bring especially intense downpours. As a small, densely built island city-state, Singapore has invested heavily in flood-control infrastructure, including widened canals and the massive Marina Barrage, but sudden intense thunderstorms can still cause flash flooding on low-lying roads within minutes, particularly during high-intensity squalls that drop a significant portion of a month’s rain in an hour. Because the island is so compact, storm cells that form nearby can affect the entire city within a short window, giving residents little lead time from a standard forecast alone. Radar imagery is heavily used locally as a result, letting people track a cell’s exact position and movement in real time. Singapore’s National Environment Agency operates the country’s weather radar network.
