South Korea experiences a nationwide rise in morning temperatures on Monday, March 16, driven by north and northwest winds. Meteorological forecasts indicate morning lows at or above 0°C across most regions, though wind chill factors up to 15°C colder will make conditions feel harsher.
Temperature Outlook
A fresh cold air mass advances from the northwest, centering on key areas before moving southward. Expect morning lows ranging from -3°C to 7°C and daytime highs between 10°C and 16°C. Northern and highland regions face frost risks despite average flat temperatures (minimums -3°C to 5°C, maximums 10°C to 14°C).
City-specific forecasts include:
- Morning lows: Seoul 1°C, Incheon 1°C, Suwon -2°C, Chuncheon -2°C, Gangneung 4°C, Cheongju 0°C, Daejeon -1°C, Jeonju 1°C, Gwangju 2°C, Daegu 2°C, Busan 6°C, Jeju 6°C.

Fine Dust Levels
Air quality deteriorates with ‘bad’ fine dust concentrations forecast for Seoul, southern Gyeonggi, western Gangwon, Sejong, North Chungcheong, Daegu, and North Gyeongsang. Other areas remain at ‘moderate’ levels, though Daejeon, Jeonbuk, Busan, Ulsan, and South Gyeongsang show early signs of rising to ‘bad’ in the morning.
Visibility and Safety Notes
Dense fog reduces visibility to under 1km in spots centered on low-level atmospheric flows. Stronger winds in valleys and open areas like golf courses thicken fog layers, necessitating expanded safety distances and cautious operations during clear intervals.
