On Friday the 27th, most of the country will be mostly clear with daytime temperatures rising sharply. However, fine dust concentrations will be high, and the large gap between day and night temperatures requires extra care for health.
According to the Korea Meteorological Administration, morning lows across the country will be 2–11 degrees and daytime highs 15–25 degrees. With temperatures remaining above normal, the difference between day and night will widen to around 15 degrees.
The country will be mostly clear, but the air will be very dry, mainly in the central region and North Gyeongsang. In areas where dry weather advisories continue, caution is advised to prevent wildfires and other fires.
Fine dust is expected to be at a "bad" level in all regions. The greater Seoul area and North Chungcheong are forecast to see "very bad" levels at times in the morning and at night. In the morning, stagnant air will lead to an accumulation of fine dust, and from night, fine dust from overseas will flow in on northwesterly winds, further thickening concentrations.
Waves will be 0.5–1.0 meters on the East Sea, West Sea and South Sea coastal waters. In the inner offshore waters (the offshore area within about 200 km of the coastline), wave heights are expected to be 0.5–1.0 meters on the East Sea, West Sea and South Sea.
