Busan Weather & What to Pack, Season by Season

Average temperatures, rainfall, and sea breeze patterns for each season in Busan, plus what to wear and pack, so you're not caught off guard by the swing in temperature.

Average Temperature and Weather by Season

Season	Months	Avg. Temp	Weather Notes
Spring	Mar–May	~10–20°C	Big day/night swing, occasional yellow dust — a good season for cherry blossoms and beach walks
Summer	Jun–Aug	~25–33°C	Hot and humid, monsoon season late June through July, typhoons mostly cluster in Aug–Sep
Autumn	Sep–Nov	~12–23°C	The most comfortable and stable season, with a clear day/night gap — great for outdoor plans
Winter	Dec–Feb	~-5–7°C	Coastal wind makes it feel colder, occasional snow but rarely sticks around

What to wear: Spring (Mar–May)

Layer up — a light jacket or knit over a long-sleeve top works well. Mornings and evenings run cool, so pack a light windbreaker, and bring a mask if you're sensitive to yellow dust.

What to wear: Summer (Jun–Aug)

Stick to breathable short sleeves and shorts. Indoor AC tends to run strong, so a light layer is worth carrying, and during monsoon season a compact umbrella and waterproof shoes are a must.

What to wear: Autumn (Sep–Nov)

A long-sleeve top with a light jacket covers most days. The day/night gap is noticeable, so pack a slightly heavier layer you can put on and take off as needed.

What to wear: Winter (Dec–Feb)

A heavy coat, scarf, gloves, and warm base layers are essential. Coastal spots like Haeundae and Gwangalli get windy, so it feels several degrees colder than the number on the forecast.

Packing Checklist

A plug adapter — Korean outlets are round two-pin 220V, so bring one if your home country uses a different plug shape
Any regular medication you take
Comfortable walking shoes (many sights like Gamcheon Culture Village and Taejongdae involve slopes and stairs)
A portable charger and cable
Rain gear (monsoon season in summer, occasional snow in winter)
A transit card or small cash (some street food stalls only take cash)
