The Korea Forest Service issued a forecast predicting that autumn foliage across the Korean Peninsula would reach its peak in late October. The forecast noted that the peak timing was expected to be approximately 0.8 days later than the average of the previous five years. Following this forecast, the first autumn foliage of the season was officially observed at Seoraksan at an altitude of 1,708 meters. While the onset of coloring at Seoraksan aligned with the annual average, it occurred four days earlier than the previous year. To assist with monitoring, meteorological and forestry agencies have implemented services providing real-time visual updates from various mountain locations. Recent developments indicate that unseasonably high temperatures in early autumn, attributed by experts to climate change and rising temperature trends, are expected to delay the peak foliage timing. The timing of the peak varies depending on the agency used for measurement: the Korea Meteorological Administration defines the peak as when 80% of a mountain is colored, whereas the Korea Forest Service considers it reached when 50% of leaves are colored. Seoraksan reached its peak on October 16, one day earlier than the annual average. Other major mountains, such as Palgongsan, are expected to peak later in November. To assist tourists, the Korea Tourism Organization and the Korea Forest Service have identified 36 major autumn spots, including coastal driving routes along the East, West, and South Seas, with viewing windows extending from late October through mid-November.
