Around October 2-3, Northern Vietnam will experience a second cold air wave, likely similar in intensity to the first one, resulting in a slight temperature drop, possibly accompanied by rain and thunderstorms.
Forecast for a New Cold Air Wave in Northern Vietnam
The meteorological agency has reported that at the beginning of October, Northern Vietnam may welcome a second cold air wave. This cold air mass is expected to have a similar intensity to the first wave of the season, meaning temperatures in the North will not drop significantly.
According to the forecast, around October 2-3, temperatures in Northern Vietnam will decrease by 3-4 degrees Celsius.
In Hanoi, the maximum temperature is expected to drop from 31 degrees Celsius to 27-28 degrees Celsius, while the minimum will decrease to 24 degrees Celsius.
In Cao Bang, one of the provinces that will be affected earliest by the cold air, the maximum temperature will be 29 degrees Celsius, with a minimum of 21 degrees Celsius.

The National Center for Hydro-Meteorological Forecasting has added that cold air activity will gradually increase from October, with an upward trend in frequency and intensity starting from November.
Intense cold weather and widespread frost in the Northeastern region may appear in the second half of December (compared to the average over many years); during January and February 2025, intense cold and frost may continue to occur widely. There is a need to be cautious about the possibility of prolonged cold spells lasting about 5-8 days, along with frost and ice phenomena in the mountainous areas of Northern Vietnam.
Although cold air is expected to start appearing from September, the average temperatures in September and October across the country are generally 0.5 to 1 degrees Celsius higher than the average of many years; November is expected to be approximately at the average level for this period.
Weather Forecast for the Coming Days
According to the meteorological agency’s forecast, from the night of September 26 to October 4, the Northern region will have scattered rain and thunderstorms at night, with sunny days; specifically, from September 28 to October 1, there is a likelihood of scattered rain and thunderstorms.
The Central region will have sunny days, with evening and nighttime rain and thunderstorms in some areas; particularly, from the night of October 1 to 3, scattered rain and thunderstorms are expected in the area from Thanh Hoa to Thua Thien Hue.
The Central Highlands and Southern regions will have evening and nighttime rain and thunderstorms in some areas, with sunny days; specifically, in the Southern region, scattered rain and thunderstorms are expected on the evenings of September 26-27. During thunderstorms, there may be occurrences of whirlwinds, lightning, and strong winds.
According to the National Center for Hydro-Meteorological Forecasting, from December 2024, the ENSO phenomenon is expected to remain in a La Niña state with a probability of about 65-75%.
From December 2024 to February 2025, typhoons/tropical depressions in the East Sea are likely to appear at approximately the average level of many years and may impact the mainland. “Be cautious about the possibility of typhoons/tropical depressions forming directly in the East Sea,” warns the National Center for Hydro-Meteorological Forecasting.
The rainy season in the Central, Central Highlands, and Southern regions may end later than usual (around the second half of December 2024).
The Central Highlands and Southern regions may experience off-season rains in January and February 2025.
