Skies will be mostly clear across South Korea on Tuesday the 6th, though commuters will face a chilly morning.
Morning lows are forecast at 3 to 14 degrees Celsius, with daytime highs of 20 to 24 degrees.
Expected morning lows in major cities are 11 degrees in Seoul, 11 in Incheon, 6 in Chuncheon, 12 in Gangneung, 9 in Daejeon, 11 in Daegu, 11 in Jeonju, 11 in Gwangju, 14 in Busan and 18 in Jeju.
Daytime highs are projected at 22 degrees in Seoul, 22 in Incheon, 21 in Chuncheon, 22 in Gangneung, 22 in Daejeon, 23 in Daegu, 23 in Jeonju, 24 in Gwangju, 24 in Busan and 23 in Jeju.
Morning temperatures will hover around 10 degrees in inland areas nationwide, making for chilly conditions. In inland and mountainous parts of Gangwon State, temperatures will drop to 5 degrees or below. Winds will also blow strongly, with gusts of about 55 kilometers per hour — 70 kph in mountainous areas — making it feel even colder.
Across most of the country, the gap between daytime and nighttime temperatures will widen to about 15 degrees.
Fine dust levels will be rated "good" nationwide thanks to smooth atmospheric dispersion.
Waves will run 0.5 to 2.0 meters in coastal waters of the East Sea, 0.5 to 3.0 meters off the West Sea and 0.5 to 1.5 meters off the South Sea.
In inner offshore waters — those within about 200 kilometers of the coastline — waves are expected to reach 0.5 to 3.5 meters in the East Sea, 1.0 to 3.5 meters in the West Sea and 1.0 to 2.5 meters in the South Sea.
