Early summer heat with highs up to 32 degrees Celsius; dense fog in western regions until morning

Much of South Korea is set to experience early summer heat on Monday, with daytime highs forecast to reach around 30 degrees Celsius and potentially up to 32 degrees in some locations. The weather agency has advised citizens to take precautions against the heat, especially in the Seoul metropolitan area where the highest perceived temperature could reach 31 degrees.

In addition to the warmth, western parts of the country, including Incheon and parts of Gyeonggi province, can expect dense fog in the morning, reducing visibility to under 200 meters in some areas. Scattered showers are also possible in inland regions, including parts of Jeollanam-do and Gyeongsangnam-do provinces, though rainfall amounts are expected to be light, between 5 to 10 millimeters.

The forecast indicates that morning low temperatures will range from 13 to 20 degrees Celsius, while afternoon highs will be between 24 and 32 degrees. Cities like Seoul are expected to see a high of 32 degrees, while Busan will be cooler at 27 degrees.

Despite the fluctuating weather conditions, the air quality is projected to be favorable, with fine dust levels rated as 'good' to 'normal' nationwide. The weather is expected to remain generally clear with occasional clouds, except for Jeju Island, which will transition from cloudy to partly cloudy conditions.
