Children's Day on Monday will bring clear and sunny spring weather across the country, though a jacket is advisable for outings given the wide temperature gap between day and night.
Morning lows will range from 3 to 13 degrees Celsius, while daytime highs will reach 19 to 24 degrees, similar to or slightly below seasonal norms. The temperature gap between day and night will be around 15 degrees across most inland areas, widening to as much as 20 degrees in parts of the Gyeongsang region.
The country will generally be clear, but fog may form in some central regions and the Jeolla area from dawn through morning. Strong winds are expected in parts of the central west coast, Gangwon's mountainous and east coast areas, and the northeastern mountainous and northern east coast regions of Gyeongbuk.
Along the east coast, high swells may push strongly onto beaches or overtop rocky shores and breakwaters, requiring caution against coastal safety accidents.
Sea waves will rise 0.5 to 2.0 meters off the east coast and 0.5 to 1.5 meters off the west and south coasts. In the inner offshore waters (within about 200 kilometers of the coastline), wave heights are expected to reach 0.5 to 2.5 meters in the East Sea and 0.5 to 2.0 meters in the West and South Seas.
