Gwanghwamun Square and the Cheonggyecheon stream in Seoul remained largely empty on a recent holiday morning due to oppressive heat and humidity [1].

The lack of crowds at these central landmarks highlights the immediate impact of extreme weather on urban mobility and public gathering habits in South Korea.

Citizens typically flock to these areas for leisure, but the combination of high temperatures and moisture has shifted activity indoors. According to YTN News, the square was uncharacteristically quiet as people avoided the stifling conditions [1].

Reporting from the site indicated that even with cloud cover providing some relief from direct sunlight, the temperature remained near 30°C [1]. This heat was compounded by humidity levels exceeding 70% [1].

Reporter Jung Young-soo said the weather was hindering outdoor activities for those visiting the area on the holiday morning [1]. The conditions created a stifling environment that deterred the usual crowds from gathering at the stream and the square [1].

An anchor for YTN News said the square is desolate because the scorching heat has continued for several days while humidity remains high [1]. This pattern of persistent heat has made the city's primary pedestrian hubs less attractive for residents and tourists alike.

While Gwanghwamun Square often serves as a hub for cultural events and political gatherings, the current climate has effectively cleared the space, leaving only a few citizens utilizing umbrellas or pavilions for shade [1].

The emptiness of Seoul's most iconic public spaces during a holiday demonstrates how high humidity can amplify the perceived impact of moderate temperatures. When humidity exceeds 70%, the body's ability to cool itself through sweat is diminished, making 30°C feel significantly more oppressive and driving urban populations away from open-air infrastructure toward climate-controlled environments.
