Seoul's climate features four distinct seasons with hot, humid summers and cold, dry winters separated by moderate spring and autumn months. Precipitation is concentrated in the warmer half of the year, while winter brings significantly less rainfall.
Seoul's weather patterns are shaped by the East Asian Monsoon system, created by the specific land-sea distribution across the Korean Peninsula. This large-scale atmospheric circulation has influenced the region's climate conditions for millennia.

Plan visits according to the season, as summer and winter require very different clothing and preparations for comfort. Understanding current conditions helps when scheduling outdoor activities and adapting to the city's weather patterns.
Winter brings recurring cycles of extreme cold lasting several days when the Siberian High-pressure system expands southward. These predictable cold waves notably shape how the city functions during the coldest months.
