Weather Autumn Cold Snap Returns…Seoul and Suwon at 2°C, Paju at -2°C with 'Subzero Wind Chill'

On the morning of the 28th, cold air from the northwest pushes in strongly, bringing the coldest weather of the fall so far, with temperatures in Seoul and Suwon dropping to 2°C.

According to the Korea Meteorological Administration, along with the influx of cold air and strong cold winds, the perceived temperature during the morning commute is expected to remain mostly in subzero ranges.

On the 28th, the nationwide morning low temperature will be distributed between 1-6°C, with significant drops centered on the capital region and inland Gyeonggi. Morning low temperatures in major regions are as follows: ▲Seoul 2°C ▲Incheon 3°C ▲Suwon 2°C ▲Paju -2°C ▲Yeoncheon -3°C ▲Chuncheon -1°C ▲Daejeon 3°C ▲Daegu 4°C ▲Gwangju 5°C ▲Busan 7°C. In northern Gyeonggi and inland and mountainous areas of Gangwon, temperatures will drop below freezing with widespread frost and ice formation.

Daytime highs will remain at ▲Seoul 12°C ▲Suwon 13°C ▲Incheon 12°C ▲Paju 11°C ▲Daejeon 14°C ▲Daegu 15°C ▲Gwangju 15°C with cold winds blowing even during the day, creating chilly conditions.

This cold spell will peak on the morning of the 28th and gradually recover to normal temperatures from the afternoon of the 29th onward, but chilly seasonal transition weather is forecast to continue in the mornings and evenings for the time being.

[Guide to Coping with Cold Snap in Daily Life] "Here's How to Prepare for Subzero Wind Chill on Your Commute"

• Appropriate clothing and cold-weather accessories for commuting

Layering with multiple thin clothes rather than one thick garment (shirt+cardigan/vest+coat) is effective for maintaining warmth and adapting to temperature rises during the day. Since the perceived temperature on the commute drops into subzero ranges, wearing an outer coat like a lightweight puffer jacket or wool coat that blocks cold winds and wrapping a scarf, muffler, or gloves around exposed areas such as the neck and hands can raise the perceived temperature by 2-3°C or more.

• Caution for people with cardiovascular diseases on outdoor activities

Sudden exposure to cold air can constrict blood vessels and rapidly raise blood pressure. Elderly people and those with cardiovascular diseases should refrain from morning outdoor exercise, and it is important to keep the neck warm when going outside.

• Prevention of cold damage and frost injury to harvest-season crops

Subzero temperatures and frost are expected, particularly in northern Gyeonggi and inland mountainous areas, so farmers should cover harvest-season crops with insulation covers or conduct advance inspections of heating facilities to prevent cold damage.

• Watch for early morning fog and black ice on roads

On bridges, tunnel entrances and exits, and shaded roads, there is a risk of black ice forming from dew that froze overnight, so reduced speed is necessary on the morning commute.
