Large numbers of Seoul residents and visitors crowded the COEX Aquarium this week to escape humid and hot weather [1, 2].
The surge in attendance highlights a growing trend of citizens seeking climate-controlled indoor environments to avoid the physical discomfort of South Korea's summer humidity. This shift in leisure activity puts increased pressure on urban infrastructure and popular tourist sites during peak weather events.
Located within the COEX Mall in the Gangnam district of Seoul, the aquarium became a primary destination for those avoiding the outdoors [1, 2]. The venue's temperature-controlled environment provided a sanctuary for families and tourists who found the outdoor conditions oppressive.
Reporter Moon Sang-ah of YTN News said from the scene that there was a high volume of people navigating the exhibits [1]. According to the report, visitors spent their time immersed in the attractions of marine life while staying in a comfortable indoor setting [1].
"Visitors are deeply immersed in the charm of marine creatures in a pleasant indoor environment," Moon said [1].
The influx of people was particularly notable as it coincided with a holiday, which typically increases the volume of local travel and leisure outings [1, 2]. The combination of a public holiday and extreme weather created a bottleneck of visitors within the facility's tunnels, and viewing areas [1].
While the aquarium is a year-round attraction, the specific drive toward indoor venues during heatwaves reflects a broader urban pattern in Seoul. Residents increasingly rely on integrated mall complexes like COEX to maintain social and recreational activities without exposure to the elements [2].

This trend underscores the critical role of 'indoor cities' and integrated complexes in Seoul's urban planning. As summer temperatures and humidity levels fluctuate, the reliance on private, climate-controlled spaces for public recreation increases, potentially shifting economic activity away from traditional outdoor markets and parks toward commercial mall environments.
