A quick, year-round overview of monthly and seasonal weather in Busan. Use this page to get a feel for which months and seasons match your travel style.

Busan weather at a glance

  • Busan is coastal, and sea breeze often changes how the temperature feels—especially on beach and headland routes (Haeundae, Gwangalli, Taejongdae).
  • Winters can feel milder than Seoul, but windy evenings can feel surprisingly sharp near the water.
  • Summers are hot and humid, and monsoon rain plus typhoon influence (Jul–Sep) can disrupt coastal plans with heavy rain and wind.
  • Sea fog and overcast days can close views. When visibility opens up, it’s often worth doing viewpoints first.
  • Itineraries can be walk-heavy (beach promenades, markets, hillside neighborhoods), so shoes and layers matter.
Jan · Feb

Milder numbers, but sea wind can sharpen the feel

Avg low 0–4°C / high 8–12°C · Wet days: 4–7 per month / 25–60 mm

  • It can look mild on paper, but wind can drop comfort quickly near the coast.
  • Exposed spots (beaches, breakwaters, viewpoints) feel colder if you linger.
  • Frequent indoor/outdoor transitions can make short outdoor walks feel colder.

Suggested outfits

  • · Coat/puffer
  • · Warm inner layers
  • · Scarf/gloves for wind

A note for travelers

“Milder than Seoul” can be true, until wind becomes the main variable.

Mar · Apr

Walkable spring with cooler breezy evenings

Avg low 6–12°C / high 14–20°C · Rainy days: 6–9 per month / 60–130 mm

  • Afternoons can feel mild, while sea breeze cools evenings.
  • Rain plus wind can feel chillier than expected.
  • Thin layers help for longer seaside walks.

Suggested outfits

  • · Trench/light jacket
  • · Shirts/sweatshirts/light knits
  • · Comfortable walking shoes

May · Jun

Pleasant May; June turns humid and rainy

Avg low 14–20°C / high 21–27°C · Rainy days: 7–12 per month / 100–220 mm

  • June monsoon stretches can slow pacing and increase wet surfaces.
  • A thin layer helps with strong indoor AC.

Suggested outfits

  • · Breathable tops
  • · Light cardigan/wind layer
  • · Umbrella + water-friendly footwear

A note for travelers

In monsoon season, stability comes from indoor anchors and flexible routing.

Jul · Aug

Hot, humid summer with heavy rain bursts

Avg low 23–25°C / high 29–32°C · Rainy days: 9–13 per month / 200–350 mm (variable)

  • Downpours can pause coastal routes.
  • Indoor AC contrast makes a thin layer useful.

  • · Thin indoor layer

A note for travelers

Sep · Oct

Autumn makes you walk more than planned—shoes matter.

Nov · Dec
