Two notable phenomena occur: Samo (the “three cold days” following the winter solstice) and Ilwol Samsal (unusually mild spells in late January). Climate change has introduced greater variability—warmer average winters but increased polar vortex disruptions, causing sudden extreme cold spells (“Arctic outbreaks”). Fine dust (PM2.5) levels often peak in winter due to stagnant air and transboundary pollution, leading to health advisories.
Winter sports tourism is a significant economic driver. Following the 2018 PyeongChang Winter Olympics, Korea developed world-class ski resorts (e.g., Yongpyong, Alpensia, High1) attracting domestic and international visitors. Ice skating rinks (e.g., Seoul Plaza’s seasonal rink) and indoor snow parks operate. Conversely, winter also strains the construction and outdoor service industries, while energy demand for heating spikes. The government implements “winter energy conservation” programs and subsidies for vulnerable populations (e.g., energy vouchers ). winter season in korea
Winter is intrinsically tied to Korean traditions. The lunar calendar includes the holiday of Seollal (Lunar New Year), falling in late January or February. Families gather for charye (ancestral rituals), eat tteokguk (rice cake soup, symbolizing aging a year), and play traditional games like yutnori . Seasonal foods include hot stews ( kimchi jjigae , samgyetang —despite its summer association, it is also consumed for warmth), roasted sweet potatoes ( gun-goguma ), and hotteok (sweet pancakes). The winter landscape is celebrated in art and poetry, especially the “Four Gentlemen” (plum blossom, orchid, chrysanthemum, bamboo)—with the plum blossom symbolizing resilience.
