Climate
The climate of Seoul is classified as being a moderate climate. Like all temperate climate areas, Seoul experiences 4 distinct seasons: Winter (December - Mid - March), Spring (Late March - Beginning of June), Summer (June - Mid - September) and Autumn (Mid - September - End of November). The most beautiful seasons to visit Seoul are Spring and Autumn. Most of the precipitation in Seoul falls in between June and September.
Winter is very cold and very dry, the most brutal month being January. The temperature can go as low as minus 12 Degrees. Snow doesn't come very often but when it does, it melts very quickly. However, Winter is the best time to use your ondol (Underfloor Heating).

Spring normally starts quite cool and possibly wet, but as the season progresses, the weather becomes warmer and spring flowers begin to appear such as azaleas and adonis. In addition, Spring holds all the Korean Spring Flower Festivals (See Cultural Features --- > Festivals). Spring, along with Autumn, are shorter than Summer and Winter. However, the only drawback in Spring, is Yellow Dust (otherwise known as Asian Dust). Yellow Dust emanated from the Mongolian and Chinese deserts and has now spread to Korea and Japan.
Summer is a wet, humid season in Seoul. The East Asian Monsoons cause The East Rainy Season (In Korea, known as jangma) to have constant precipitation in the late Spring and upcoming Summer. Thunderstorms also occur, normally 2 to 5 days each month. Fogs develop when the humidity is high and there is cold air mass. Typhoons arise through Mid-Summer and early Autumn. At least once a year, a typhoon would pass Seoul and therefore, causing heavy rainfall.

Autumn is the season between the humid Summer, and the cold Winter. This season is quite short compared to Summer and Winter. The weather is neither too cold or too hot and is a wonderful time to visit Seoul. There aren't many rainy days in Autumn, so it can be quite dry, until a typhoon may appear and cause heavy rain.
