Hot humid weather will return across South Korea once Wednesday’s rain clears completely. Forecasters expect temperatures to rise significantly throughout most regions following recent stormy conditions. Rain and strong winds swept across the country earlier this week, including Gyeonggi Province overnight Tuesday.
Fortunately, this rainfall should ease by Wednesday afternoon, though humidity levels remain notably high. Consequently, perceived temperatures will climb quickly once the rain moves away from the peninsula. Heat advisories are expected to persist across much of the country afterward.
Specifically, feels-like temperatures will reach approximately 33 degrees Celsius throughout many affected regions nationwide. Meanwhile, North Gyeongsang Province could experience perceived temperatures reaching around 35 degrees Celsius today. Additionally, tropical nights are forecast for Gangwon Province’s east coast and several southern regions.
These areas include North Chungcheong Province, the Gyeongsang region, Jeolla region and Jeju Island. Overnight temperatures there will likely remain above 25 degrees Celsius throughout the night. Wednesday’s rain originated from moisture linked to Typhoon Bavi’s remnants over eastern China.
This system temporarily eased hot humid weather conditions, prompting some heat advisories to lift. Rainfall should end nationwide by afternoon, with most regions receiving between 5 and 20 millimeters. However, Ulleungdo, the Dokdo islets and parts of North Jeolla Province could receive higher amounts.
Daytime highs will range broadly from 27 to 36 degrees Celsius across different cities. Seoul should reach 29 degrees, while Busan climbs to 31 and Daegu hits 35. Gangneung and Gwangju will also experience notably high temperatures throughout the day.
The Korea Meteorological Administration urged citizens to remain cautious regarding heat-related illness risks. Furthermore, officials highlighted growing food safety concerns as persistent heat and humidity continue affecting the region. Moving forward, residents should prepare for extended stretches of hot humid weather nationwide.
