We had a dusty Christmas Eve in most parts of the nation and unfortunately conditions are likely to stay the same on Christmas Day.
Let's connect to our Natalie Seok at the Weather Center for more details. Natalie.
Ultra-fine dust levels soared on Tuesday, forcing many people to wear masks. If you wore one today, don't put it away just yet as you might need it tomorrow on Christmas day, especially in Gyeonggi-do Province, Sejong, the Chungcheong Provinces, Jeolla-buk-do Province, Daegu, and Gyeongsang-buk-do where fine dust is expected to reach "bad" levels.
Christmas is shaping to be a cloudy one nationwide, with sudden rain forecast for Jeju Island around tomorrow afternoon.
Taking a closer look at our readings for Christmas Day
Seoul wakes up to -2 degrees Celsius, -4 in Chuncheon, and 9 in Jeju.
Daytime high will peak to double digits, with the mercury reaching 7 in Seoul, 11 in Daegu, and 15 in Busan and Jeju.
Meanwhile, the rain clouds above Jeju are expected to move towards Chungcheong-nam-do Province by Thursday morning.
Conditions will return to freezing cold by Friday, with Seoul's morning low plunging to minus 6 degrees. Air quality however will bounce back to bearable or normal levels by the end of the week.
I'll leave you with the weather conditions around the world.
