South Korea has four relatively distinct seasons, with spring, summer, autumn, and winter returning every year. Although the exact timing changes slightly from year to year, seasonal changes are very noticeable compared to many other countries.
In a typical year, spring lasts for about three months, summer for another three months, autumn is usually the shortest season at around two months, and winter often feels the longest at roughly four months. There are also transition periods when the weather is less predictable, and some years spring can feel unusually long. In contrast, autumn is almost always the shortest season.
Although winter lasts the longest, heavy snowfall is generally concentrated within only one or two months. The cold season extends well beyond the period when snow is common.
If you plan to live in South Korea for more than a year, there is a good chance you will eventually need clothing for every season. Because of the country's wide temperature range, it is difficult to rely on one wardrobe throughout the year.
If you arrive during autumn, you are in a relatively convenient situation. Autumn clothing can usually be worn throughout much of spring as well. During summer, simply removing outer layers and wearing lightweight clothing is often enough. The main additional purchase you will need is proper winter gear, such as a thick insulated jacket, gloves, and other cold-weather accessories.
On the other hand, if you arrive during winter with only heavy winter clothing, you may later need to purchase separate outfits for spring, summer, and autumn as the weather changes.
Summer daytime high temperatures are generally between 30°C and 35°C, although heat waves can occasionally push temperatures even higher.
During winter, average daily low temperatures are commonly around -5°C to -10°C, with even colder periods occurring some years. When precipitation falls during these cold conditions, it is typically snow rather than rain.
For most long-term residents, it is more practical to buy at least some seasonal clothing after arriving in Korea instead of trying to pack an entire year's wardrobe in advance. This approach makes it easier to adapt to the local climate while avoiding unnecessary luggage.
