Vietnam is set to experience a dramatic temperature variation tomorrow, with forecasts indicating a range of 19 degrees Celsius between morning and afternoon temperatures. The morning will start with lows around 12 degrees Celsius, while the afternoon could see highs of up to 31 degrees, particularly in Daegu.

The Korea Meteorological Administration has reported that most areas will experience a mix of clouds and clear skies, with the chill of early autumn reaching its peak. This significant temperature difference necessitates careful health management, as it could lead to seasonal illnesses.

In terms of precipitation, the forecast varies by region. Light rain is expected in the capital region and northern parts of Gangwon Province, with potential rainfall of less than 0.1 mm early in the morning. Conversely, Jeju Island is predicted to receive heavier rain, ranging from 5 to 10 mm, starting in the afternoon and continuing into the night.

Looking at major cities, Seoul is expected to have cloudy weather with temperatures between 18 and 25 degrees Celsius, while Daegu will enjoy clearer skies with temperatures ranging from 18 to 31 degrees. Jeju Island will see temperatures between 22 and 27 degrees, with rain primarily affecting the mountainous areas.

The recent successful event held at the Daegu Dalseong Sports Park, titled '2026 Daegu Social Welfare Workers' Festival,' showcased the pleasant autumn weather that is settling across the country. However, the stark contrast between day and night temperatures can weaken immunity and lead to colds, so it is advisable to dress in layers and stay updated with the latest weather information to maintain health during this transitional season.
