Seoul offers a dynamic climate with four clearly defined seasons, each bringing unique beauty and experiences. Understanding the weather patterns will help you pack appropriately and plan activities. Here’s a seasonal breakdown:
🌸 Spring (March-May)
Spring is arguably Seoul’s most beautiful season! Temperatures range from 5°C (41°F) in March to 20°C (68°F) in May. The city transforms with cherry blossoms (usually early April), creating pink canopies along streets and parks. Light layers are essential – mornings can be chilly while afternoons feel warm. Expect occasional yellow dust storms (hwangsa) from Mongolia.

☀️ Summer (June-August)
Prepare for hot, humid weather (25-35°C / 77-95°F) and monsoon rains. July brings the rainy season (jangma) with heavy downpours – waterproof shoes and umbrellas are mandatory! August is hottest, but air-conditioned cafes and nighttime Han River activities provide relief. Humidity often exceeds 80%.

🍂 Autumn (September-November)
Crisp air and vibrant foliage define autumn! Temperatures drop from 22°C (72°F) in September to 5°C (41°F) in November. The city glows with red and gold leaves – mountains like Bukhansan become hiking paradises. This dry, sunny season is perfect for palace visits and outdoor festivals. Pack light jackets.

❄️ Winter (December-February)
Cold and dry with temperatures between -5°C (23°F) and 3°C (37°F). January is coldest, sometimes dropping below -10°C (14°F). Snowfall is moderate but creates magical scenes at palaces and ski resorts. Bundle up with thermal layers, coats, and boots! Indoor attractions (cafes, museums, jjimjilbangs) shine during this season.
