You will need to bundle up very warmly tomorrow morning.

The air has turned noticeably chilly, feeling much like early winter already.

Tomorrow morning is expected to be the coldest so far this autumn.

With cold wave advisories issued for various parts of the country, morning temperatures tomorrow are projected to plummet by about 10°C compared to yesterday, with Seoul dropping to 5°C, Paju to 0°C, and Daegwallyeong to minus 3°C.

This unseasonably early cold snap will not last very long.

Temperatures will remain somewhat below seasonal averages until the morning of the day after tomorrow, which marks Sanggang (one of the 24 solar terms), but temperatures will rise back to normal levels starting from the afternoon.

Skies will be clear nationwide tomorrow, and frost is expected to form and water is expected to freeze mainly in inland and mountainous areas.

Looking at the detailed morning lows by region, Seoul and Daegu are expected to drop to 5°C, and Chuncheon to 1°C, while daytime highs are forecasted to reach 16°C in Seoul and 17°C in Gwangju.

Rain is expected to begin on Jeju Island and the southern coast on Friday, and spread from the weekend through Monday next week across Gangwon Yeongdong and regions in Chungcheong and further south.
