Spring usually arrives with a gentle invitation, but this weekend, the weather in South Korea is delivering a more aggressive greeting. A sweeping system of spring rain and powerful winds is moving across the peninsula today, Saturday, April 4, creating a sharp tension between the season’s blooming beauty and the sudden volatility of the atmosphere.
For many, the timing is particularly frustrating. The rain arrives just as cherry blossoms are in full peak, threatening to wash away the petals prematurely and disrupt the weekend outings that define early April. While the rain is widespread, the impact is far from uniform, with the southern regions bearing the brunt of the storm’s intensity.
A Divided Intensity: From Light Rain to Heavy Downpours
While much of the country is seeing a steady spring rain, the southern coast and Jeju Island are facing a much more severe scenario. In these areas, rainfall is concentrating at rates of 10 to 30mm per hour. The projected totals are significant: the mountains of Jeju could see over 150mm of rain, while Jeonnam and Gyeongnam provinces are bracing for up to 80mm. Other regions will experience a more modest range, between 5mm and 60mm.
The rain is accompanied by a formidable wind component. Across the country, skies remain mostly overcast, but the real danger lies in the gusts. In mountainous and coastal areas, sudden wind bursts exceeding 20 meters per second are expected, with Jeju’s mountain peaks potentially seeing speeds up to 25 meters per second.
Temperature fluctuations continue to be a point of concern for residents. Morning lows started between 2 and 10 degrees Celsius, with Seoul at 11 degrees and Daejeon and Jeonju at 12 degrees. Daytime highs will climb to 18 degrees in Seoul and Daejeon, and reach 19 degrees in Daegu and Busan.
The Outlook: A Brief Reprieve Before Monday
Those hoping for a quick return to sunny spring weather may be disappointed. The current system is only the first part of a volatile sequence. Forecasts indicate that another round of nationwide spring rain is poised to arrive this coming Monday.

Following Monday’s precipitation, the atmosphere is expected to shift again, bringing a brief period of colder temperatures. This “flash chill” suggests that the transition into stable spring weather remains elusive, leaving residents to navigate a cycle of rain, wind, and fluctuating temperatures.
Will the rain affect the cherry blossom season?
Yes. Given that cherry blossoms are currently in full bloom, the combination of heavy rain and strong gusts—particularly the 20m/s+ winds—is likely to accelerate the falling of petals, potentially shortening the viewing window for the public.
Which regions are facing the most severe weather?
Jeju Island and the southern provinces (Jeonnam and Gyeongnam) are the primary areas of concern, with the highest expected rainfall (up to 150mm in Jeju mountains) and the strongest wind gusts.
What should be expected for the start of the work week?
Monday is expected to bring another round of nationwide rain, followed by a temporary dip in temperatures that will make the weather experience noticeably chillier.
With the weekend’s blossoms at risk and more rain on the horizon for Monday, how are you adjusting your plans for the coming week?
