The Weather Administration considers the first autumn foliage to occur when about 20% of the entire mountain, starting from the summit, is colored. The peak foliage is defined as when about 80% of the mountain is colored.

Deciduous trees generally begin to change color when the daily minimum temperature drops below 5 degrees Celsius, and the Weather Administration explains that the lower the temperature after September, the earlier the foliage change occurs.

The average daily minimum temperature in the Seoul area from the 1st to the 17th of this month was 12.3 degrees Celsius, similar to the average year, marking the start of the foliage change. The Weather Administration provides nationwide famous mountain foliage status on the Weather Nuri website.
