Clouds and rain are keeping temperatures across South Korea well below recent levels today as the summer season begins.
The arrival of "Soman," the traditional start of the Korean summer rainy season, brings significant precipitation and cloud cover that suppresses heat across the peninsula. This shift in weather patterns affects daily activity and agricultural planning during a critical seasonal transition.
Weather forecasts indicate a cool day for major urban centers. Seoul is expected to reach a high of 20 °C [2], while Gwangju is forecast to hit 21 °C [4]. Daejeon is expected to be slightly warmer with a high of 22 °C [3].
The most severe weather is concentrated in the east. Gangwon-do Province is facing forecasts of heavy rainfall reaching up to 80 millimeters [1]. This localized intensity contrasts with broader regional estimates; an MSN weather planner reported rainfall around one inch, or approximately 25 mm, overall [5].
The combination of cloud cover and steady rain has prevented the typical temperature spikes associated with the onset of summer. Residents in Gangwon-do are advised to monitor local alerts as the heavy rain continues to move through the province.

The onset of Soman marks a meteorological shift where moisture-laden air suppresses temperatures but increases the risk of flash flooding, particularly in mountainous regions like Gangwon-do. The discrepancy between regional forecasts and general weather planners suggests highly localized precipitation patterns, which often characterize the start of the East Asian rainy season.
