Between the night of February 10 and early February 11, a weak cold front from the east brought back light rain to northern Vietnam. According to the National Center for Hydro-Meteorological Forecasting, this weather pattern will cause overcast skies and light rain during the night and early morning hours.

However, the cold front is weak, so rainfall is expected to be brief, and temperatures will remain largely unchanged. By the afternoon of February 11, conditions are forecast to improve with dry skies and rising temperatures.

From February 13 (the 26th day of the lunar calendar), northern Vietnam is expected to enjoy sunny weather, which will last through February 17 (the first day of Lunar New Year). During this period, daytime highs will range from 23–26°C, with some areas in the northwest reaching 26–29°C. Nighttime lows will hover between 16–20°C, with some mountainous regions dropping below 15°C.

A new cold spell is expected between February 18–19 (the second and third days of Tet), bringing light rain and a slight temperature drop across the north. This will be followed by a stronger cold front on February 21–22, likely resulting in scattered rain and colder weather, especially in mountainous regions, where severe cold may occur.

For Hanoi specifically, the night of February 10 and morning of February 11 will be cloudy with occasional light rain and chilly conditions. The lowest temperature is expected to range from 16–18°C. By midday and afternoon of February 11, the rain will ease and temperatures will rise to 20–22°C.

From the night of February 12 to February 20, Hanoi will experience light rain in some areas, with mist or light fog in the early mornings. Nights and mornings will remain chilly. Between February 12–17, daily highs will average 23–26°C, with lows around 16–19°C.

Based on the forecast, February 16 (the 29th day of the lunar calendar) will see daytime highs in Hanoi around 25°C, while temperatures at midnight - New Year’s Eve - will dip to about 18°C. On February 17 (the first day of Tet), the city is expected to see highs of 24°C and lows of 18°C.

Around February 18 (the second day of Tet), another wave of cold air will likely bring scattered light rain and cause daytime temperatures to fall slightly by 1–2°C.

From February 21–22 (the fifth and sixth days of Tet), a stronger cold front is forecast to hit, bringing more widespread rain and cooler temperatures. In Hanoi, daytime highs will drop to 20–22°C, with nighttime lows of 14–16°C.

Meanwhile, the Southern Regional Hydro-Meteorological Center reports that Ho Chi Minh City will experience mostly sunny days and dry nights from February 11–20 (the 24th day of the lunar month to the fourth day of Tet). The only exception will be isolated showers and thunderstorms in the evening of February 11–12.

Temperatures will remain warm, with lows between 21–25°C and highs ranging from 30–34°C - some areas may exceed 34°C.
