Hanoi sits in or near Vietnam’s Red River Delta, where a monsoon climate brings a hot, wet season from May to October and a cooler, drier winter. Most of the year’s rain falls between June and September, driven partly by the southwest monsoon and partly by typhoons that track in from the South China Sea.
The capital sits along the Red River, and its Old Quarter drainage system, built more than a century ago, is still tested by the most intense summer downpours. Vietnam’s National Center for Hydro-Meteorological Forecasting monitors the region closely during typhoon season, and live radar is a useful complement to official storm-track forecasts for watching individual rain bands move through Hanoi.
