Spring Season (Mar–May)

Usually announces its arrival with bright yellow forsythia flowers (kanari) along streets and highways. The season often starts out cool and maybe wet, but gradually the weather warms up and other spring flowers begin making their appearance, including magnolia and cherry blossoms. The various species of trees sprout leaves of various shades of green and reds. We also know that spring is here when we see the new crop of strawberries, while the appearance of Korea’s small yellow melons tells us summer is on the way.

Summer Season (Jun–Aug)

Is one of the proofs that Korea is a land of extremes in that it is as hot and humid and the Korean winter is cold and dry. Summer is relatively hot and humid with monsoon rains beginning near the end of June and lasting until mid to late July. Occasionally, between the announcement of the beginning and the end of monsoon season, there is no rain. And then the rains come. Typhoons around Japan can also bring heavy to Korea in August. Summer temperatures can go over 38°C with an average of 20°C between June and September. Cold watermelon, sweet juicy peaches and cold noodles offer some consolation to the muggy weather, which generally ends by September, when the evenings turn refreshingly cool.

Fall Season (Sep–Nov)

Is probably the best time of year in Korea. The weather is cooler and dryer, but still pleasantly warm and sunny. As the season progresses, the leaves change colors and harvesting begins. Fall is the time of Chuseok, Korean Thanksgiving. At this time of year, you’ll find crisp, sweet apples in the market along with the unique Korean pear (known in North America as the Asian pear), huge purple grapes and the fragrance of roasting chestnuts and gingko nuts on the streets. One of the most important autumn events is Kimjang – the time for making kimchi. Families get together still to prepare this unique fermented dish according to their traditional family recipes. Fall kimchi is considered by many Koreans to be the best kimchi of the year. Fall is also a wonderful to go out of Seoul and explore Korea. The weather is great and the countryside is beautiful.

Winter Season (Dec–Feb)

Anyone who is familiar with Seoul’s winter will tell you, the weather can be brutal. The weather can get cold, windy and dry, all at the same time. But don’t let that stop you from coming to Seoul during the winter! Unlike the summer months with seemingly never ending monsoons, Korean winters are characterized by clear blue skies and fresh crisp mornings (+ the cold). So, put on your warmest coat and come enjoy the amazing city with some of these exclusively winter activities that will make your trip to Seoul in the winter totally worth it.
