Seoul Weather

Seoul’s weather offers a distinct four-season experience, each presenting its own unique charm and challenges. Understanding these seasonal shifts is key to planning a visit or acclimating to life in the vibrant South Korean capital. Spring, arriving in late March and lasting until May, is arguably the most beloved time in Seoul. The city bursts into life with cherry blossoms, azaleas, and other colorful blooms. Temperatures gradually rise from chilly to pleasantly warm, averaging between 10°C and 20°C (50°F to 68°F). However, spring in Seoul can also bring “hwangsa,” or yellow dust, originating from the Gobi Desert. This dust can affect air quality, so it’s wise to check pollution levels and wear a mask on particularly dusty days. Summer, from June to August, is hot and humid. Temperatures often climb above 30°C (86°F), with humidity levels making it feel even hotter. June also marks the start of the monsoon season, known as “jangma,” which brings frequent and heavy rainfall. While the rain can be a nuisance, it also cools down the city and brings lush greenery to the parks and mountains. Expect occasional typhoons during late summer, potentially causing strong winds and flooding. Lightweight, breathable clothing and an umbrella are essential for navigating Seoul’s summer weather. Autumn, from September to November, is a glorious time to experience Seoul. The intense heat and humidity of summer give way to cooler, drier air. The city transforms into a kaleidoscope of vibrant fall colors, with maple and ginkgo trees painting the landscapes in shades of red, orange, and yellow. Temperatures range from 10°C to 20°C (50°F to 68°F), making it ideal for outdoor activities. Autumn is a popular time for hiking, picnicking, and exploring the many parks and gardens in Seoul. Winter, from December to February, is cold and dry. Temperatures can drop below freezing, often reaching -10°C (14°F) or lower. Snowfall is common, creating picturesque winter scenes. While the cold can be intense, the dry air makes it more bearable compared to the humid summers. Layering clothing is crucial, and wearing warm coats, hats, gloves, and scarves is essential for staying comfortable. The Han River often freezes over, and the city is beautifully illuminated with festive lights during the holiday season. In summary, Seoul’s weather offers a dynamic and varied experience. Spring and autumn provide pleasant temperatures and stunning natural beauty, while summer is hot and humid with the monsoon season, and winter is cold and dry with occasional snowfall. Understanding these seasonal patterns is key to enjoying all that Seoul has to offer, regardless of the time of year.
