On Tuesday the 30th, the temperature difference between day and night will be around 10 degrees, especially in inland areas, leading to a large daily temperature range.
Morning lows are forecast at 13–19 degrees, with daytime highs at 23–27 degrees.
From early morning to morning, dense fog is expected in inland Gyeonggi, inland Chungcheong, and inland North Jeolla, so caution is advised for traffic safety.
While there will be occasional clouds nationwide, there will be scattered showers from daytime to evening in inland Gyeonggi; inland and mountainous Gangwon; northern Chungcheong; and southern inland North Gyeongsang.
Expected rainfall from the showers is less than 5 mm in northern inland Gyeonggi; inland and mountainous Gangwon; northern South Chungcheong; and northern North Chungcheong, and around 5 mm in Daegu and southern inland North Gyeongsang.
Fine dust concentrations will be at "good" to "moderate" levels nationwide due to smooth atmospheric dispersion.
Waves will be 0.5–1.0 meters off the East and South Seas and 0.5 meters off the West Sea. In the inner offshore waters (the offshore area within about 200 km of the coastline), wave heights are forecast at 0.5–1.5 meters in the East Sea and 0.5–1.0 meters in the West and South Seas.
