South Korea's second-largest city, Busan, has weather all its own, shaped by mountains like Geumjeongsan and Hwangnyeongsan meeting the South and East Seas. From spring sea fog to typhoons in late summer and autumn, to sharply different conditions between neighborhoods perched on steep hillsides between mountain and coast — here's a breakdown of Busan's weather, historical records, and seasonal tips.
Busan's terrain has mountains large and small — Geumjeongsan, Hwangnyeongsan, Jangsan — running right up to the coast around the mouth of the Nakdong River. Surrounded by mountains on three sides yet broadly facing the South and East Seas, it's strongly shaped by a maritime climate: winters are milder than in other major cities, but summer humidity runs high and the city is frequently hit directly by typhoons.
From spring through early summer, warm, moist air over the South Sea cools as it passes over colder water, frequently producing thick advection fog. Visibility can drop suddenly on coastal roads and sea bridges like Gwangan Bridge, so drive with extra care.
Sitting at the peninsula's southeastern tip, Busan often lies in the path of typhoons moving north from the South Sea. In late summer and early autumn, watch more closely than elsewhere for strong winds, swell, and flooding in low-lying coastal areas.
Hillside neighborhoods on steep slopes between mountain and sea, like Gamcheon Culture Village, see stronger winds and different temperature conditions than low-lying coastal areas. Even within Busan, coastal, flat, and hillside neighborhoods can feel quite different.
Spring often brings reduced visibility from sea fog. In summer, the maritime climate keeps heat waves somewhat milder than inland, but high humidity makes the muggy feeling linger. Into early autumn, Busan is frequently hit directly by typhoons, and winter is milder than other major cities but calls for caution around strong coastal winds.

| Record | Value | Date |
|---|---|---|
| Record high | 37.3°C | 2016-08-14 |
| Record low | -14.0°C | 1915-01-13 |
| Heaviest daily snowfall | 29.5cm | 2005-03-05 |
On days with a sea fog advisory, avoid coastal roads and bridges if you can, and slow down significantly if you must drive. Ahead of a typhoon, stay away from low-lying coastal areas and breakwaters, and in hillside neighborhoods, secure anything that could be blown around. For general threshold-by-threshold guidance on UV, feels-like temperature, and fine dust, see what to do.
Because conditions vary a lot between Busan's coastal, flat, and hillside neighborhoods, searching for and adding a specific neighborhood like "Haeundae-dong" or "Yeongdo" in sanCheck gives you a more accurate weather and outdoor-activity score. Save the places you check often — home, work — and tap between chips to compare.
