The National Center for Hydro-Meteorological Forecasting predicts that damp conditions will begin in the north of Vietnam at the end of this month and last until April.
According to Nguyen Van Huong, head of the weather forecasting department at the National Center for Hydro-Meteorological Forecasting, damp conditions typically occur in spring.
During this period, cold air masses no longer move in a north-south direction but shift eastward, causing northeast to east winds in the northern region.
This leads to increased humidity in the air, particularly in the northeast and Hanoi, often reaching saturation levels and resulting in dampness.
“The dampness usually occurs in late February, March, and April,” Huong said.
“Initial assessments suggest that this year’s dampness will not be as strong as in 2024.”
He also noted that early on Saturday morning, the ongoing cold air strengthened and began affecting the central region.
By the following day, the cold air caused temperatures to drop to 10-13 degrees Celsius in Hanoi and many provinces of the Red River Delta.
In mountainous areas such as Lang Son, Cao Bang, and Lai Chau Provinces, temperatures ranged from 8-10 degrees Celsius, while high mountain areas like Sa Pa in Lao Cai Provinces, Nguyen Binh in Cao Bang Province, and Dong Van in Ha Giang Province saw temperatures between 5-7 degrees Celsius.
The cold air is expected to continue affecting other regions of central Vietnam within Saturday, reaching parts of the south-central region as well.
In the north, temperatures are expected to remain extremely cold, with the lowest temperatures in the Red River Delta ranging from 9-12 degrees Celsius.
In mountainous areas, temperatures will be between 5-8 degrees Celsius, and in high mountain areas, some places may experience temperatures below 3 degrees Celsius, with a possibility of sleet and frost.
In the north-central region, temperatures will range from 11-14 degrees Celsius, and from Quang Binh to Thua Thien-Hue Provinces, temperatures will range from 14-16 degrees Celsius.
In Hanoi, Saturday’s weather will be cloudy with occasional rain in some areas.
It will remain very cold, with daytime temperatures reaching only 13-15 degrees Celsius, and nighttime temperatures dropping to 10-12 degrees Celsius.
“This severe cold spell is expected to last until around Monday, with the coldest period occurring today and early tomorrow morning,” Huong commented.
As February is still the peak winter month, the north and north-central regions will continue to experience cold air waves throughout the month.
These northeast monsoons are likely to bring more severe cold, with average daily temperatures below 13 degrees Celsius widely across these two regions.
