The 7th marks the Dae-seol (Major Snow) solar term, but generally mild weather continues nationwide without any snow forecast. While it will be mostly cloudy, temperatures will vary by region.

According to the Korea Meteorological Administration, the morning low temperatures on the 7th will range from -4°C to 8°C, and the daytime highs are expected to reach between 8°C and 17°C. In particular, the inland areas of the Gyeongsang region will experience a temperature difference of around 15°C between day and night. Accordingly, citizens should pay special attention to their health. In Seoul, the morning low is expected to be 3°C, with a daytime high of 12°C.

Fine dust levels are expected to reach poor levels in most parts of the country. This phenomenon is caused by stagnant air and can negatively affect respiratory health. Especially, dry weather warnings are in effect for the mountainous areas of Gangwon, the East Coast, the northeastern mountains and East Coast of North Gyeongsang, Daegu, and parts of South Gyeongsang. These areas are expected to have very dry air and strong winds, so caution is needed to prevent wildfires.

Sea waves are expected to be 0.5 to 1.5 meters in the East Sea and South Sea coastal waters, and 0.5 to 2.0 meters in the West Sea coastal waters. In the outer seas, wave heights are expected to be 1.0 to 3.5 meters in the East Sea, 0.5 to 3.0 meters in the West Sea, and 0.5 to 2.0 meters in the South Sea. These marine conditions require caution for navigation and fishing operations.

The nationwide rise in temperatures is analyzed as part of winter climate change. Meteorological experts view these temperature changes as influenced by climate change, and citizens need to prepare accordingly. Health management and measures to cope with fine dust are required in response to these temperature changes.
