Northern and North Central Vietnam Face Prolonged Fog and High Humidity

Weather Update: February 11-20

The National Center for Hydro-Meteorological Forecasting has reported that starting February 11, the Northern and North Central regions of Vietnam will experience prolonged fog, high humidity, and occasional light rain. While afternoons will see some sunshine, mornings and nights will remain damp and cold, with mountainous areas facing very cold temperatures and potential frost.

Foggy Mornings and Wet Conditions to Persist in the North

From February 11 to 12, the Northern and North Central regions will have:

Light rain and scattered fog in the early morning. Drizzle and dense fog overnight, especially in the Northeast. Cold temperatures, with mountainous areas experiencing extreme cold

From February 12 to 20, provinces such as Lao Cai, Yen Bai, Southern Son La, Hoa Binh, and the Northeast will continue to experience:

Persistent drizzle and fog overnight and in the morning. Some clearing in the afternoons, but overall cloudy skies

Hanoi and the Northern Plains

Hanoi and surrounding provinces will see: Sunshine only in the afternoons. Cloudy and gloomy weather for the next five days. Rain likely at night and early mornings on Wednesday, Thursday, Saturday, and Sunday. Maximum daytime temperature below 21°C

What’s Causing This Prolonged Wet Weather?

The dominant Southeast wind is bringing in moist air, leading to continuous fog, drizzle, and high humidity across most of the North.

On Thursday (Feb 15) and Sunday (Feb 18), a weak cold front will move eastward, reinforcing these damp conditions. However, because the cold air travels over the sea before reaching land, it carries additional moisture, intensifying rain and fog.

Mountainous Regions at Risk of Frost and Freezing Conditions

In the Northwest, conditions will be: Cold with occasional rain. Morning fog, clearing in the afternoon. Very cold temperatures in the mountains, with frost possible in high-altitude areas

Lowest temperatures: 12-15°C, but below 11°C in some locations

Highest temperatures: 18-21°C, with some areas exceeding 22°C

The Northeast and Hanoi will see:

Foggy mornings, occasional light rain. Afternoon sunshine but continued cold conditions

High-altitude regions should prepare for frost

Lowest temperatures: 12-15°C, but 8-11°C in the mountains, and below 8°C in high-altitude areas

From Thanh Hoa to Hue, expect: Light rain in some areas. Morning fog and mist. Sunshine in the afternoon in northern areas. Cold temperatures, particularly at night and in the morning

Lowest temperatures: 14-17°C, slightly warmer in southern areas

Highest temperatures: 20-23°C

Marine Weather: Strong Winds and Rough Seas

High winds and rough seas will affect multiple areas:
