The best time of year to visit Seoul in South Korea

The large amount of people who live and work in Seoul at only 613 kilometers help to ensure that the average temperature in the city is a few degrees higher than in the countryside which surrounds the city. This is because the buildings and streets retain the heat, an effect that is especially noticeable during the summer evenings.

Seoul has relatively cool and sometimes quite mild winters. However not every winter is the same in Seoul. Some winters there will be no days below the freezing point and other years you can experience severe frost. That same unpredictability is reflected throughout almost the entire year. In the summer months, temperatures are mainly tempered by clouds and precipitation.

From May to September you will see the most rain, with rainfall amounts rising in July and August to 300 mm and sometimes more than 400 mm per month. In this period there is also the possibility that Seoul gets hit by a hurricane. The hurricane season runs from June to December in this region.

During the months of May and October you are most likely to experience good weather with pleasant average temperatures that fall between 20°C and 26°C.
