About Yongsan-gu in September
Yongsan-gu benefits from dual cooling effects — the Han River's northern bank moderates summer temperatures along the waterfront, while Namsan's western slopes funnel downslope breezes through the district in the evening. The vast open space of the former US military base at Yongsan Garrison creates a notable low-density thermal break in an otherwise dense urban fabric.
