Spring Rain Sweeps Across South Korea, Chilly Weather Follows

South Korea is bracing for a day of heavy spring rain as forecasts predict widespread precipitation across the country today, April 6, 2026. The rain is expected to accompany strong winds and possible thunderstorms, creating a tumultuous start to the week.

According to multiple weather reports, the rain will begin in the morning and is likely to continue until the afternoon in most areas. The Korea Meteorological Administration warns that the rain could be quite intense, especially in the southern regions, where rainfall amounts may reach up to 30mm. In Seoul, the expected precipitation is around 5mm, highlighting a stark difference in rainfall across regions.

Weathercasters are advising residents to prepare for potentially hazardous conditions, as the storm could bring heavy rain and strong winds and even hail in some areas. "You’ll need to bring an umbrella today," said a local meteorologist, emphasizing the need for caution due to the possibility of severe weather events. As the storm passes, temperatures are expected to drop significantly, leading to a chilly evening.

This morning, temperatures ranged from 7 to 12 degrees Celsius, with highs later in the day reaching between 13 and 19 degrees. In major cities like Seoul and Daejeon, the high is forecasted to be around 15 degrees, dropping 2 to 5 degrees compared to previous days. The chill is expected to intensify tomorrow and Wednesday, with morning lows potentially dipping to around 0 degrees in inland areas.

Adding to the complexity of today’s weather, dust from the Gobi Desert and Inner Mongolia is expected to mix with the rain, leading to what is being termed as "mud rain." This phenomenon may pose health risks, prompting health officials to advise the public to take extra care during this period. Following the rain, air quality is anticipated to worsen, with fine dust levels expected to rise to unhealthy levels in the afternoon.

As the rain subsides, a cold front will sweep through, bringing brisk conditions that could lead to a late-season cold snap, often referred to as "flower-snap cold." This term describes the sudden drop in temperatures that can affect blooming flowers and plant life, reminding residents to dress warmly and protect their gardens.

In the coming days, the weather outlook suggests a return to clearer skies on Tuesday, April 7, with temperatures stabilizing but remaining cool. The forecast indicates that the country will see more rain later in the week, particularly on Thursday and Friday, as another system moves in.

In light of these developments, residents are encouraged to stay updated on weather conditions and to take precautions against the cold and potential health impacts from dust and pollen in the air. The government is monitoring the situation closely, providing updates as necessary.

As the week progresses, South Koreans will need to adapt to the fluctuating temperatures and weather patterns, ensuring they are prepared for both the rain and the subsequent chill that spring can bring.
