Rain season
Hanoi has two distinct wet seasons: a long hot monsoon (May–October) and a cool drizzly winter (November–March) fed by the northeast monsoon. Typhoons from the South China Sea can bring extreme rain August–October. Annual totals reach around 1,700mm. The cool, damp 'crachin' drizzle in winter is a defining feature of northern Vietnam's climate.
