Tomorrow, September 23, marks the autumn equinox, when day and night are of equal length. The weather across the country is expected to be generally clear and bright, according to the Korea Meteorological Administration on September 22.
On Wednesday, the weather will be influenced by a high-pressure system located over the northeastern sea of the East Sea, resulting in occasional clouds but mostly clear skies nationwide.
However, temperatures are expected to drop in the morning, particularly in inland areas, while daytime temperatures will rise, leading to a significant temperature difference of over 10 degrees. Residents are advised to take care of their health.
Morning low temperatures will range from 12 to 21 degrees Celsius, while daytime highs will be between 22 and 29 degrees, which is similar to or slightly above the seasonal average.
In major cities, morning low temperatures are forecasted to be 19 degrees in Seoul, 15 degrees in Chuncheon, 17 degrees in Daejeon, 18 degrees in Gwangju, 16 degrees in Daegu, and 20 degrees in Busan.
Daytime highs are expected to reach 29 degrees in Seoul, 27 degrees in Chuncheon, 28 degrees in Daejeon, 28 degrees in Gwangju, 27 degrees in Daegu, and 27 degrees in Busan, which may feel somewhat hot during the day.
In the eastern coastal areas of Gangwon and Gyeongsang provinces, as well as Jeju Island, there may be periods of cloudiness and occasional rain due to easterly winds from the high-pressure system. Expected rainfall amounts are around 5 to 20 mm.
Inland areas may experience dense fog in the morning, so special attention should be paid to traffic safety.
Fine dust levels are expected to remain at 'good' to 'moderate' levels nationwide due to smooth atmospheric circulation.
