Seoul Weather

Seoul, South Korea experiences four distinct seasons, each painting the city in unique colors and presenting its own set of weather conditions. Understanding these patterns is key to packing appropriately and planning your visit for the most enjoyable experience.

Spring (March – May): Spring in Seoul is arguably the most beautiful time of year. After a long winter, the city bursts into bloom with cherry blossoms, azaleas, and forsythia. Temperatures gradually rise from chilly beginnings to pleasantly warm afternoons. Expect average daily temperatures ranging from 5°C (41°F) in early March to 18°C (64°F) by late May. Rainfall is moderate, and the air can sometimes be dusty due to yellow dust blown in from the Gobi Desert. Light layers are recommended, as temperatures can fluctuate significantly throughout the day. Don’t forget a light jacket or sweater and perhaps a face mask on particularly dusty days.

Summer (June – August): Summer in Seoul is hot and humid, punctuated by a monsoon season that usually lasts from late June to mid-July. July is the wettest month, with frequent heavy downpours. Average daily temperatures soar, ranging from 22°C (72°F) to 30°C (86°F) or even higher. The humidity can make the temperature feel even more oppressive. Lightweight, breathable clothing is a must. An umbrella or raincoat is essential during the monsoon season, and insect repellent can be helpful, especially in parks and green spaces. Stay hydrated and seek air-conditioned refuge during the hottest parts of the day.

Autumn (September – November): Autumn in Seoul is another exceptionally beautiful season. The vibrant foliage of the maple and ginkgo trees transforms the city into a spectacle of reds, oranges, and yellows. The weather is generally dry and sunny, with pleasant temperatures. Average daily temperatures range from 20°C (68°F) in early September to 7°C (45°F) by late November. Similar to spring, layering is a good strategy as the days can be warm, but evenings can be cool. Pack a light jacket or sweater, and enjoy the stunning autumn scenery in Seoul’s parks and mountains.

Winter (December – February): Winter in Seoul is cold and dry, with occasional snowfall. The Siberian air masses bring freezing temperatures and strong winds. Average daily temperatures range from -5°C (23°F) to 3°C (37°F). Sub-zero temperatures are common, especially at night. Heavy winter clothing is essential, including a warm coat, hat, gloves, and scarf. Layers are crucial for adapting to indoor heating. While the city is often dusted with snow, heavy snowfalls are less frequent than in some other regions of Korea. Indoor activities and warming Korean cuisine are popular choices during the winter months.

In summary, Seoul’s weather offers something for everyone, but it’s always best to be prepared for the specific conditions of the season you plan to visit. Check the forecast before your trip and pack accordingly to ensure a comfortable and enjoyable experience in this dynamic city.
