Data base date: July 3, 2026
On July 3, the Korea Meteorological Administration announced data analyzing climate characteristics and the cause of the delay in the rainy season for June 2026. The timing of the start of the rainy season was explained as the result of a combination of air currents and ocean conditions around the Korean Peninsula.
Just because the rainy season started late does not mean that the overall risk of precipitation is reduced. Rain may be concentrated in a short period of time or regional precipitation variations may increase, so the starting point and amount of precipitation must be examined separately.
Local governments and citizens should inspect drainage channels, underground spaces, and landslide-prone areas in advance based on the latest forecasts and special reports. Long-term forecasts are data that show trends, and actual responses should prioritize short-term forecasts and on-site situations.
