The National Center for Hydro-Meteorological Forecasting has issued a forecast of notable weather trends in the next month (ie from now until January 10, 2026).
The 2025 storm season is likely to stop
From the beginning of 2025 to now, there have been 21 storms/tropical depressions active in the East Sea (including 15 storms and 6 tropical depressions), breaking the record previously set in 2017 with 20 storms. Therefore, the upcoming forecast information about the storm season is of further interest.
According to the meteorological agency, from now until early January 2026, there is little chance of storms or tropical depressions appearing in the East Sea. According to the average data of many years, during this period, there will be about 0.8 tropical cyclones in the East Sea and 0.1 will make landfall in Vietnam.
Notable weather information in the coming time is the activity of the northeast monsoon. During the forecast period, cold air tends to operate weaker than the average of many years but is still likely to cause severe cold spells, especially in the mountainous and midland areas of the North.
In the next month, the average temperature in most areas across the country will be approximately the same as the average of many years; in the Northern and North Central regions, it will be 0.5 - 1 degree Celsius higher, in some places over 1 degree Celsius higher than the average of many years in the same period.
Strong winds caused by cold air can cause large waves at sea and affect the activities of ships. Thunderstorms, tornadoes, and lightning can negatively affect traffic, production, and public health.
In addition, it is necessary to be on guard against the possibility of severe cold spells causing the lowest temperature to drop sharply, especially in the northern highland areas that are likely to be accompanied by frost and ice.
Central region still needs to be on guard against heavy rain
Regarding the rainfall trend, during the forecast period, the total rainfall in the Northern, Thanh Hoa and northern areas of Nghe An is generally from 30 - 60mm. The southern area of Nghe An and Ha Tinh will have common rainfall of 70 - 150mm, 5 - 20mm higher than the average of many years.
From Quang Tri to Da Nang city, the coastal areas of Quang Ngai to Dak Lak and northern Khanh Hoa provinces will have rain from 70 - 150mm, some places over 200mm (commonly 20 - 50mm lower than the average of many years).
The Central Highlands region has a total rainfall of 5 - 15mm, 5 - 10mm lower. Other areas are generally expected to have rain from 20 - 40mm, 5 - 10mm lower than the average of many years in the same period.
In the provinces/cities from Quang Tri to Da Nang, the east of Quang Ngai province to Dak Lak and Khanh Hoa, there is a possibility of widespread heavy rains (concentrated in the first half of the forecast period).
In particular, the Northern region and Thanh Hoa to Ha Tinh are likely to experience rain, moderate rain and scattered thunderstorms, with some heavy rain on December 13.
On a national scale, there is a continued possibility of dangerous weather phenomena such as thunderstorms, whirlwinds, lightning, hail and strong gusts of wind.
In the context of climate change, weather and climate are becoming increasingly complex with many dangerous and extreme forms such as short-term heavy rain, flash floods, landslides, etc.
Therefore, the meteorological agency recommends that authorities at all levels and people regularly update and integrate forecast and warning information on hydrometeorology in short-term bulletins of 1 - 3 days, to promptly adjust production plans and appropriate response plans, especially appropriate reservoir operation plans, ensure safety of works and downstream areas, along with ensuring safety for production and people's lives.
