Northern Vietnam is experiencing an 'unusual' cold snap.

The weather forecast predicts localized heavy rain in the Northwest region, expected to continue until April 7th. The cold air mass will also cause a slight drop in temperature in the North, with cold nights and mornings.

According to the meteorological agency, cold air activity gradually weakens from mid-April onwards.

According to the National Center for Meteorological and Hydrological Forecasting, on April 5th, the northern region will experience a weak but eastward-shifted cold front, resulting in scattered rain and showers. Specifically, the northwestern region will have localized moderate to heavy rainfall, with amounts ranging from 15 to 30 mm, and in some places exceeding 50 mm.

Localized heavy rain in the Northwest region is forecast to continue until April 7th. The cold air mass will also cause a slight drop in temperature in the North, with cold nights and mornings.

Notably, the National Center for Meteorological and Hydrological Forecasting has released a weather trend forecast for April 2025.

Temperatures in the area from Thanh Hoa to Hue are generally lower than the average for the same period in previous years, by about 0.5 - 1 degree Celsius.

Mr. Nguyen Duc Hoa, Deputy Head of the Climate Forecasting Department, National Center for Meteorological and Hydrological Forecasting, shared that in the first 10 days of April, cold air masses are likely to be more active than the multi-year average, after which the cold air mass tends to gradually weaken.

Cold air masses are likely to cause strong winds and large waves, affecting maritime activities and fishing operations at sea for fishermen.

Previously, in March, there were three cold fronts on March 5th, March 15th, and March 29th, causing three periods of intense cold and frost in the Northern region.

Severe cold spells and frosts are concentrated mainly in mountainous provinces; on March 30th alone, widespread severe cold weather occurred in the North, with the lowest temperatures in some places dropping below 10 degrees Celsius, such as: Dong Van ( Ha Giang ) 8.7 degrees Celsius, Tam Dao (Vinh Phuc) 8.8 degrees Celsius, Mau Son (Lang Son) 4 degrees Celsius…

"During the middle and end of April, hot weather tends to intensify in the Northwest and Central regions; be prepared for severe heatwaves. Hot weather will also continue to appear over a wide area in the Southeast region and tends to increase in the Central Highlands and the Southwest region," Mr. Hoa said.

Previously, localized heatwaves occurred in the Northwest, Central Highlands, and Southern regions of Vietnam. Specifically, the provinces in the Southeast experienced a widespread heatwave from March 11th to 15th, with daily maximum temperatures commonly reaching 35-37 degrees Celsius, and even higher in some areas.

Regarding rainfall trends, the total rainfall nationwide in April was generally 5-15mm lower than the multi-year average; however, some areas in the mountainous and midland regions of Northern Vietnam, Southern Central Highlands, and Southeastern Vietnam experienced rainfall 10-30mm higher than the multi-year average for the same period.

"April is a transitional month, and across the country, there is a possibility of thunderstorms, tornadoes, lightning, and hailstorms," ​​Mr. Hoa said.
