Hanoi in January: Weather & climate information

IN A NUTSHELL
  • Hanoi in January is mostly winter-like with strong freezing winds and low temperatures.
  • Yet, visitors can still enjoy barely sunny days and clear skies.
  • Though rainy days take almost half of the month, it’s not as heavy as summer months and the weather is still dry.

January is no doubt the coldest month of the year when its strong freezing wind discourages people from morning exercise sessions and ice-tea nights. In opposite, the city seems to have its busiest days of the year and streets are more crowded than usual during working hours when people are in rush to complete all the remaining works and prepare for Tet holiday. However, the climate condition like this enable visitors to enjoy the tasty hot food of Hanoi such as noodle, hot pot and roasted dishes.
