Normally in late autumn and early winter, the weather in the North is mainly sunny with daytime temperatures around 27-32°C, and air humidity is usually below 50%.

However, this year the situation is different: the cold comes early, there is a lot of rain, the autumn season only lasts about two weeks, and in the last two days there has been fog, continuous light rain, the highest temperature is about 28°C, while the humidity is still above 80%. The humidity in the air exceeds 80%, causing the floor and walls to 'sweat', and the clothes cannot dry properly.

Meteorological experts say that the dampness appearing in November is quite unusual, because according to the normal cycle, this phenomenon usually occurs from late winter to early spring (around February to April of the solar calendar) - the time when plants grow strongly.

The cause was determined to be the cold air mass weakening to the east, combined with the southeast wind from the maritime air mass entering, carrying a lot of moisture.

According to the National Center for Hydro-Meteorological Forecasting, the humid weather in the North may last until November 11, before the cold air mass strengthens from November 12, along with winds from the north to northwest at an altitude of 1,500-3,000 m, helping the North to transition to a state of clear clouds and clearer sunshine.
