Weekend Weather: Cold Snap & Snow/Rain Expected Across Korea

A significant cold snap is gripping the nation, with temperatures expected to remain frigid through Saturday. While much of the country will experience clear skies, some areas are bracing for continued snowfall and icy conditions, demanding caution from travelers and residents alike.

Widespread Cold and Potential for Icy Conditions

The Korea Meteorological Administration forecasts low temperatures ranging from -18°C to 0°C across the country on Saturday, with daytime highs expected to reach -5°C to 6°C. The combination of cold temperatures and wind will create significantly colder “feels like” temperatures.

Specific regional forecasts include Seoul (-11°C to -2°C), Busan (-1°C to 5°C), and Jeju Island (5°C to 8°C). Areas within Gyeonggi and Incheon provinces can anticipate lows between -16°C in Paaju and -5°C in coastal areas.

Did You Know? Ulleungdo and Dokdo islands are forecast to receive approximately 5mm of precipitation.

The weather agency warns of potential hazards due to icy roads and black ice, particularly in the central and southwestern regions where snowfall is anticipated. Cloud cover is expected in Jeju Province, and the southern and western regions will remain largely overcast.

Localized Precipitation

While most areas will be dry, light snowfall is possible in parts of Gyeonggi, Incheon, and Seoul, with accumulations of up to 1mm expected through the early morning hours. The western islands of Ulleungdo and Dokdo could see around 5mm of precipitation, while the southwestern inland areas of Gyeongnam Province may receive less than 1mm.

Air quality is generally good to moderate nationwide, though some areas, including Chungcheong, Honam, Daegu, and Gyeongbuk, may experience “poor” air quality during the morning. Coastal regions of Busan, Ulsan, and Gyeongnam may also see temporary periods of reduced air quality in the morning.

Expert Insight: The combination of sub-freezing temperatures and even minimal precipitation creates a significant risk of hazardous travel conditions. The potential for black ice, which is nearly invisible, is particularly concerning.

Sea conditions are expected to range from 0.5 to 2.5 meters in the East Sea, 0.5 to 2.0 meters in the West Sea, and 0.5 to 1.5 meters in the South Sea. Further offshore, wave heights are predicted to be between 1.0 and 4.0 meters in the East Sea, and 1.0 to 2.5 meters in the West and South Seas.
