During the 3.1 holiday weekend, South Korea is expected to experience warmer than average spring weather, with temperatures significantly higher than the usual range (lowest -6 to 4 degrees, highest 7 to 12 degrees). Weather expert Lee Kwang-yeon from the Korea Meteorological Administration noted that the inflow of cold air from the northern regions is limited, leading to a warm spell primarily influenced by easterly winds, particularly in the western regions of the country. However, a large temperature difference between day and night may pose health risks, particularly respiratory issues.

Weather forecasts predict minimum temperatures to range from 1-8 degrees Celsius and maximum temperatures from 7-16 degrees Celsius on Friday, February 27, while Saturday will see minimums from -4 to 5 degrees and maximums from 8 to 17 degrees. The weather will remain warmer than usual on Sunday, March 1, with forecasts ranging between -2 to 8 degrees for minimums and 8 to 15 degrees for maximums. However, there will be rain caused by a southern low-pressure system and atmospheric pressure troughs affecting the southeastern regions of South Korea, particularly on the morning of the 27th.

Rainfall expected includes 5-20mm in Jeju and around 5mm in southern coastal regions, while the mountainous areas of Gangwon may experience up to 1cm of snow. Meanwhile, dry weather is expected to persist across the central inland regions, raising concerns about fire hazards like wildfires. Coastal areas, especially in the southern East Sea and South Sea, should also be cautious of high waves and swells. The report emphasizes the importance of taking precautions against various fire risks due to ongoing dry conditions in certain regions.
