The climate of Seoul features a humid continental with dry winter, called "Dwa" in the Köppen climate classification. Seoul is classed as having a temperate climate with four distinct seasons, but temperature differences between the hottest part of summer and the depths of winter are extreme. In summer the influence of the North Pacific high-pressure system brings hot, humid weather with temperatures soaring as high as 35 °C (95 °F) on occasion. In winter the city is topographically influenced by expanding Siberian High-pressure zones and prevailing west winds, temperatures dropping as low as -20 °C (-4 °F). The bitterly cold days tend to come in three-day cycles regulated by rising and falling pressure systems, during winter snowfall can cause frosty weather in the city. The most pleasant seasons, for most people in the city are spring and autumn, when azure blue skies and comfortable temperatures are regular. Most of Seoul's precipitation falls in the summer monsoon period between June and September, as a part of East Asian monsoon season.
Seoul has a wet and very humid climate during the summer season, with cold and dry weather during the winter season. Spring (although windy) and autumn are mild but are short in duration. These seasons are considered the best time to visit Seoul.
As a temperate climate, Seoul has winter, spring, summer and autumn seasons. The monsoon season and typhoons also occurs in the summer season.
