Temperatures to Reach 30°C Nationwide, Scattered Showers Expected

South Korea is bracing for a day of early summer heat on Sunday, June 14th, with daytime high temperatures expected to reach around 30 degrees Celsius in most areas. This warmth will be accompanied by the possibility of strong showers, particularly in the afternoon and evening, across several regions including the central part of the country (excluding the Gangwon coast and mountains), North Jeolla Province, northern South Jeolla Province, and western inland areas of Gyeongsang Province. Some areas, like southeastern Gyeonggi Province and southern inland areas of Gangwon, may experience rain late into the night.

Expected rainfall amounts vary by region, with Seoul, Incheon, Gyeonggi, Daejeon, Sejong, South Chungcheong, Gwangju, and northern South Jeolla anticipating 5 to 50 millimeters. Inland Gangwon, North Chungcheong, and western inland Gyeongsang and Gyeongsang provinces are forecast to receive 5 to 30 millimeters, while Jeju Island might see less than 5 millimeters. These showers could bring sudden gusts of wind, thunder, lightning, and even hail, prompting caution for residents in affected areas.

Daytime highs will range from 25 to 31 degrees Celsius, generally aligning with or slightly exceeding the seasonal average. Major cities like Seoul will experience highs of 29°C, Busan 27°C, and Daegu 31°C. Meanwhile, coastal regions are advised to be aware of fog and high sea levels. The Yellow Sea and southwestern waters may experience sea fog until today, with visibility potentially dropping below 200 meters in some island areas. Additionally, strong lunar tides are expected to cause higher sea levels along the coasts of South Jeolla and Jeju Island from tonight, raising concerns about potential flooding in low-lying coastal areas and backflow in sewage systems during high tide.

Despite the unsettled weather, air quality is expected to be good across all regions, with fine dust levels rated 'good.' The Korea Meteorological Administration urges the public to exercise caution regarding safety along coastal areas due to the high tides.
