For the week of January 19 to 24, 2026, South Korea is expected to experience a significant and noticeable dip in temperatures as a powerful cold air mass moves across the peninsula.
The peak of this winter chill is projected for Wednesday, January 21, and Thursday, January 22, when morning lows in Seoul are forecast to hover around -14°C (6.8°F). As we are currently in the heart of the winter season, these sharp drops require extra attention to windproof outerwear and high-quality thermal layering to ensure comfort while exploring the city.
Looking toward the weekend, the forecast for Saturday, January 24, indicates a high 90% probability of snowfall nationwide.
This heavy precipitation is likely to lead to slippery road conditions and potential disruptions to public transportation, including flights and intercity trains. We strongly advise all travelers with scheduled departures or long-distance travel plans to monitor live weather updates and transport notices closely. Staying informed will be crucial for navigating the city safely during this period of high-impact weather.
Please keep in mind that these meteorological projections are based on current data and are subject to change as the pressure systems evolve. Nevertheless, we hope that with a little extra preparation—such as checking real-time apps and dressing in warm layers—all visitors to Korea can enjoy a safe and wonderful trip despite the freezing conditions.
Proper planning will allow you to experience the unique charm of Korea’s winter landscape while staying protected from the elements.
