The average temperature for the entire winter is generally 0.5 - 1 degree Celsius higher than the multi-year average. The number of days of severe cold and harmful cold in winter is also forecast to be less than the average.
In the remaining winter, we believe that the cold trend in the Northern provinces will continue to be maintained in January. The number of days of severe cold and frost in January is likely to be less than the average of many years. After the first severe cold spell, it is forecast that there may still be severe cold spells, but for a short time in the Northern region, the intensity is likely not too strong.

From April 2026, cold air continues to be able to operate, but tends to gradually decrease in intensity and frequency.
