The cold spells are mostly weak to moderate in intensity but they occur frequently, bringing light rain, drizzle and colder nights, with mountainous areas at risk of severe cold, said meteorologists.

The current cold air mass affecting northern Vietnam is expected to weaken in the coming days, allowing daytime temperatures to rise slightly. However, from late January, the northeast monsoon is forecast to become more active, sending successive cold-air surges southward.

On January 25-26, northern localities are expected to see little rain, with cold conditions mainly at night and in the early morning. A weak, east-shifted cold surge is forecast to affect northern and north-central Vietnam late on January 26 and on January 27, bringing scattered light rain to northeastern provinces, with cold conditions and locally severe cold in mountainous areas.

Another cold surge is anticipated from the evening of January 30 through January 31, causing scattered rain and a slight drop in temperatures across northern Vietnam and Thanh Hoa province in the north-central region. In early February, cold conditions are likely to persist, with fog or light mist in some areas during the morning.

During the Lunar New Year holiday period, from February 14–22, northern and north-central regions are also likely to remain under the influence of cold air. While overall cold intensity this winter may be weaker than the long-term average, episodes of severe cold and very severe cold could still occur, mainly in February, particularly in mountainous and midland areas of northern Vietnam.

From now until April 2026, average temperatures nationwide are expected to be close to the long-term average. Northern Vietnam and the Thanh Hoa–Hue corridor may see temperatures 0.5–1°C above average in February and March, though short cold spells are possible.

Central provinces from Quang Tri to Da Nang are forecast to see isolated rain, with a higher chance of showers and thunderstorms on January 28–29 and from January 31 to February 2, while northern parts of the region remain cold.

The Central Highlands and southern Vietnam will mainly experience sunny days, with isolated showers in the late afternoon or evening and cooler conditions at night and in the early morning in highland areas.
