According to the Korea Meteorological Administration on July 10, both the North Pacific High and the Tibetan High will continue to overlap and cover South Korea for the time being. As hot and humid air flows in along the edge of the North Pacific High, the heat will persist throughout the day and night, with little relief even after sunset.


On July 11, some areas of Jeju Island are expected to see rain starting in the afternoon. Over the two days of July 11 and 12, 10 to 60 millimeters of rain are forecast for the mountainous areas of Jeju, and 5 to 20 millimeters for other parts of the island.


Even during this nationwide heatwave, some regions may experience tropical nights. In most areas across the country, daytime highs are expected to exceed 30 degrees Celsius, with apparent temperatures rising to around 33 degrees Celsius. In particular, the Gyeongsang region is expected to feel especially hot, with apparent temperatures reaching about 35 degrees Celsius.


Morning lows are forecast to range from 21 to 26 degrees Celsius, and daytime highs from 29 to 36 degrees Celsius, both higher than the seasonal average.


Waves are expected to reach 0.5 to 1.0 meters in the coastal waters of the East Sea, and 0.5 to 1.5 meters in the coastal waters of the West and South Seas.



In offshore areas (up to about 200 kilometers from the coastline), wave heights are expected to be 0.5 to 1.5 meters in the East Sea, 0.5 to 4.0 meters in the West Sea, and 1.0 to 4.0 meters in the South Sea.
