Most regions across South Korea will experience a late-spring cold snap on Tuesday, April 7, with morning temperatures falling more than 5 degrees Celsius from the previous day.
Morning lows are forecast at -1 to 7°C, with afternoon highs reaching 12 to 15°C. Cold wave advisories have been issued for parts of Gangwon Province as cold air pushes southward from the northwest, sending temperatures 5 to 10 degrees lower than the day before. Strong winds will drive wind chill temperatures even lower.
Skies will be generally clear nationwide. However, fog with visibility below 1 kilometer is expected in inland areas of Jeolla and southern inland Gangwon Province from pre-dawn through the morning hours. Fog will be particularly dense near rivers and lakes along inland roads.
Wave heights in coastal waters are forecast at 0.5 to 2.0 meters in the East Sea, 0.5 to 1.0 meters in the West Sea, and 0.5 to 1.5 meters in the South Sea. Offshore swells (within approximately 200 kilometers of the coastline) are expected to reach 1.0 to 4.0 meters in the East Sea, 0.5 to 1.5 meters in the West Sea, and 0.5 to 2.5 meters in the South Sea.
