Today’s Weather on September 28: Late Summer Heat, Large Temperature Swings, Dense Fog Warning, and Commute Outfit Tips
1. Dense Fog on the Commute and Traffic Safety
This morning, very dense fog with visibility under 200 meters is affecting the inland and mountainous areas of Gangwon, northern Chungcheong, the southern coast of Jeolla, and the inland areas of Gyeongsang, triggering an emergency alert for commute traffic safety. On roads where visibility drops sharply, maintaining a following distance more than double the usual and practicing slow driving are the most reliable ways to prevent accidents. When passing through dense fog, it is wise to turn on your fog lights and headlights to clearly indicate your vehicle’s position to other drivers. Office workers using public transportation are also advised to leave home a bit earlier than usual to allow for potential bus or subway delays. Mr. Kim Cheol-su, a driver, shared that he suddenly stepped on the brake when the view ahead turned white while driving on the highway in the morning, stating that he felt with every fiber of his body that slow driving is the only answer in dense fog. On days when visibility is poor, it is a top priority to refrain from aggressive lane changes or cutting in, focus entirely on the road ahead, and reach your destination safely. Checking real-time road conditions during rush hour and employing a smart driving strategy to detour around heavy congestion will help start your day smoothly.
Dense fog is expected to persist in inland areas until this morning, so maintaining a safe following distance and driving slowly are essential for commute traffic safety.
2. Late Summer Heat During the Day, Chilly Mornings and Evenings: Large Temperature Swings
Today’s afternoon high temperatures are expected to range from 24°C to 29°C, with somewhat hot weather continuing nationwide despite it being late September. The significant gap between morning lows and afternoon highs can increase physical fatigue, requiring careful health management. In Daejeon and Sejong, afternoon temperatures will reach 26°C, while parts of Seoul and the southern regions may soar close to 29°C, making summer short-sleeve outfits feel appropriate during the midday heat. However, temperatures drop sharply after sunset, so if you have evening plans or outdoor activities, you must bring a jacket to maintain your body temperature. Ms. Park Young-hee, an office worker, sighed that it was so hot during her lunch break walk near the office that she was sweating, but she felt a chill on her way home and caught a slight cold, admitting she didn’t realize how scary the seasonal temperature swings could be. On days with such extreme temperature changes, the wisest approach is to dress in layers of thin clothing to flexibly handle indoor air conditioning or night breezes. Large differences between indoor and outdoor temperatures can easily fatigue the autonomic nervous system, so it is important to drink warm water frequently and get sufficient rest to maintain a steady body rhythm.
Late summer heat around 29°C dominates the afternoon, while mornings and evenings turn chilly, so layering your clothes is essential for temperature regulation.
3. Detailed Regional Weather and Precipitation Updates
Skies will be mostly partly cloudy across the country, with trace amounts of rain (less than 0.1mm) expected in parts of Jeju Island until the morning. Looking at major cities in the Chungcheong region, Daejeon and Gongju will reach 26°C, Cheonan and Asan 25°C, Boryeong on the West Coast 25°C, and Seosan 24°C, displaying a cool and mild autumn weather. Roads in areas that received rain may be somewhat slippery, so both pedestrians and drivers should be cautious of slipping accidents. The southern regions and the East Coast also have many clouds but generally present stable weather conditions suitable for outdoor activities. Mr. Lee Min-su, a university student, expressed satisfaction, saying that he had planned a cycling trip with friends for the weekend, and today’s cloudy but not hot weather provided the perfect environment for outdoor exercise. Since there are subtle temperature differences and changes in cloud cover by region, it is important to develop the habit of carefully checking the weather information for your specific area before going out. Determining in advance whether you need an umbrella or a light windbreaker based on the meteorological forecast will help you enjoy a comfortable day.
Except for trace rain in Jeju, the rest of the country will be partly cloudy with temperatures ranging from 24°C to 29°C depending on the region.
4. Cool Autumn Weather and Outdoor Activity Trends
As cool breezes begin to blow in the mornings and evenings, the number of people enjoying outdoor sports such as post-work runs or weekend marathons is exploding. People who previously stuck to indoor exercise due to the scorching heat are now running in parks or along the Han River to fully enjoy the autumn atmosphere. The apparel industry is also aggressively targeting demand for outdoor fashion items like jackets, cardigans, and sneakers by conducting large-scale autumn discount events. It has become a common sight for office workers who usually avoid exercise to join running crews to breathe in the cool air, boosting both their health and vitality. Mr. Choi Min-jun, an office worker, smiled and said that thanks to the cool weather, he started running lightly in the park with colleagues after work, enjoying the dual benefits of stress relief and weight loss. However, after outdoor exercise, body temperature can drop rapidly as sweat cools, so it is essential to wipe off sweat with a dry towel and change into warm clothes immediately. As the weather improves and outdoor activity time increases, special care must be taken to ensure adequate sun protection and hydration.
Thanks to the cool autumn weather, the number of people enjoying outdoor sports like running and marathons is increasing, and attention to body temperature management is required.
5. Transitional Season Health Management and Immunity Boosting Methods
During the transitional season, the risk of respiratory diseases such as colds and allergic rhinitis increases significantly due to large temperature swings and dry air. Since our bodies consume a lot of energy adapting to rapid temperature changes, it is crucial to strengthen immunity with nutritious food and sufficient sleep more than usual. Frequently eating seasonal fruits rich in vitamins and drinking warm tea is greatly helpful in preventing seasonal colds and maintaining balanced hydration. It is also wise to maintain indoor humidity at an appropriate level and ventilate regularly to fundamentally block environments where viruses can linger. Mrs. Kim Hyun-sook, a housewife, shared her secret, saying that her whole family used to be coughing all the time during the transitional season, but this year, by drinking warm ginger tea every morning and thoroughly washing hands after going out, they have stayed very healthy. Like this, small daily hygiene habits and health routines become the strongest shield for enjoying a vibrant autumn without visiting the hospital. An active attitude is required to listen to your body’s signals and manage your condition with light stretching and rest before fatigue accumulates.
Immunity tends to drop due to large temperature swings and dry air, so preventing seasonal illnesses requires sufficient hydration and strict hygiene management.
