The Northeast monsoon is coming, how long will the cold in the North last?
The Northeast monsoon has intensified, causing the North and North Central regions to feel cold at night, with temperatures below 16°C in some places, lasting until October 24.
On the evening and night of October 22, the Northeast monsoon continued to affect many places in the Central Central region. The Bach Long Vi area recorded strong Northeast monsoon at level 7, gusting to level 9; Con Co at level 6, gusting to level 7; Ly Son at level 6, gusting to level 8. Inland, the Northeast monsoon reached level 3-5, and in coastal areas at level 6.
Under the impact of storm No. 12 combined with the Northeast monsoon, coastal areas from Quang Tri to Da Nang have winds gradually increasing to level 7, gusting to level 8-9, and rough seas.
According to the National Center for Hydro-Meteorological Forecasting, this year's northeast monsoon tends to come earlier and stronger than the average of many years.
From December 2025 to January 2026, the Northeast monsoon will continue to strengthen, causing severe cold in the North, especially in the second half of December 2025.
In the North and Thanh Hoa, the Northeast monsoon causes a sharp drop in temperature, making the nights and mornings noticeably colder, and the mountainous areas extremely cold. The lowest temperature is commonly 19–22°C, in the midlands 17–19°C, and in the highlands below 16°C in some places.
Hanoi area does not rain, at night and early morning is directly affected by the Northeast monsoon so the weather is cold 19-22°C, high humidity, causing a cold feeling when the wind blows strongly.
At sea, the Northeast monsoon combined with the circulation of storm No. 12 creates strong winds of level 7-10, gusting to level 12 in the North East Sea and Hoang Sa area. Waves are 3-7m high, and the sea is very rough.
The Gulf of Tonkin also experiences strong northeast monsoon winds of level 7, gusting to level 9, with waves 2-4m high.
The sea area of Quang Tri - Quang Ngai (including Con Co, Ly Son, Cu Lao Cham) has strong winds of level 6-8, gusts of level 10, rough seas, dangerous for small boats and fishermen fishing far from shore.
Due to the influence of the Northeast monsoon, storm No. 12 and disturbances in the upper East wind zone, provinces from Ha Tinh to Quang Ngai have experienced widespread heavy rain. Thunderstorms accompanied by whirlwinds, lightning, hail and strong gusts of wind can cause damage to agriculture, crops, houses and infrastructure.
Heavy rain also increases the risk of flooding in low-lying areas, flash floods on small rivers and streams, and landslides in mountainous areas. Urban and industrial areas may be partially flooded if the rain continues.
