Busan feels like “Korea's port and second city — beaches, a blunt dialect, and rents well below Seoul's”, while Santiagois “Three tax-free years on foreign income, six if you ask in time — with the Andes 45 minutes from your desk”. Climate is a real differentiator: Busan — milder than seoul and rarely snowy, with humid summers, a july rain season and typhoons that arrive as storm surge rather than rain. Santiago — mediterranean — hot dry summers, cool damp winters, and winter smog trapped in the valley by the andes.
