The National Center for Hydro-Meteorological Forecasting has issued a weather trend forecast for January 2025.
Regarding temperature trends, the average temperature nationwide is approximately the same as the average of many years in the same period.
In January 2025, cold air tends to be more active than in December 2024. There is a high possibility that strong northeast monsoon will cause many days of severe cold in the northern provinces of Vietnam, concentrated in the period of mid-January 2025.
Severe cold, with the risk of frost and ice, has a major impact on livestock, crops and people's health, especially in the northern mountainous areas.
Previously, in December 2024, there were 3 cold spells on December 6, December 11 and December 27. Notably, the cold spell on December 11 caused widespread cold weather in the Northern region on December 14-15 and from Thanh Hoa to Quang Binh provinces on December 15; especially in the mountainous areas of the North, the weather was extremely cold.
The lowest temperature in the above cold air mass in the North and North Central regions is generally from 11 - 14 degrees Celsius, in mountainous areas it is below 7 degrees Celsius such as: Sapa (Lao Cai) 6 degrees Celsius, Dong Van (Ha Giang) 5.2 degrees Celsius, Tam Dao (Vinh Phuc) 6.2 degrees Celsius, Trung Khanh (Cao Bang) 5.6 degrees Celsius, Mau Son (Lang Son) 3.2 degrees Celsius...
Regarding rainfall trends, total rainfall in the North and provinces from Thanh Hoa to Da Nang is generally 10-20mm lower than the average of many years. Rainfall in other areas is generally 5-10mm higher than the average of many years in the same period.
During the forecast period, the southern region of the Central region is likely to experience some scattered showers and thunderstorms, with some localized moderate and heavy rains; the southern region may experience some unseasonal rainy days. During thunderstorms, it is necessary to be on guard against the possibility of extreme weather phenomena such as tornadoes, lightning, hail and strong gusts of wind.
Heavy rain, thunderstorms accompanied by tornadoes, lightning, hail and gusts of wind can greatly affect production and people's activities.
Regarding dangerous weather phenomena at sea, in the early period (from about January 1, 2025 to January 3, 2025), the low pressure trough with an axis of about 6 - 9 degrees north latitude connects with a low pressure area in the South China Sea; then, the low pressure trough tends to lower its axis to the south and gradually fades away.
Cold air and dangerous weather phenomena at sea can cause strong winds and large waves affecting ship operations.
Previously, in December 2024, a storm appeared in the East Sea - storm number 10 of 2024, internationally named Pabuk. On December 25, storm number 10 weakened into a low pressure area in the offshore waters from Ninh Thuan to Ba Ria - Vung Tau.
