About Gangnam-gu in April
Gangnam-gu's dense cluster of glass-clad high-rises along Teheran-ro creates one of Seoul's most intense urban heat islands, with surface temperatures reaching 5–7°C above surrounding areas in summer. The district's flat terrain south of the Han River receives less natural ventilation than northern districts sheltered by mountains, making humid summer nights particularly oppressive.
