South Korea expects cloudy skies and intermittent light rain across the country through Wednesday afternoon, May 27, 2026 [1].
These weather conditions pose immediate risks to commuter safety, as the moisture creates hazardous driving conditions during the morning rush hour.
YTN News said that sporadic rain is falling in various locations across the nation [1]. While the volume of rain is expected to be low, with nationwide amounts ranging from five to 10 mm [1], the reporting team said that roads may be slippery.
"Today will remain cloudy nationwide, and rain will continue on and off until the afternoon," YTN said [1]. "Although the amount is small, the rain may make the roads slippery, so you must be careful about traffic safety" [1].
The current weather follows a period of more intense precipitation. Heavy rain fell starting Tuesday, primarily centering on Jeju Island and the southern coast [1]. One specific area in Jeju, an azalea field, recorded a significant rainfall total of 359 mm [1].
Forecasters said that a strong rain-cloud band is currently moving away from the peninsula, leaving only scattered showers in its wake [1].
Temperature readings on Wednesday morning showed Seoul at 21.5 °C and Daegu at 19.5 °C [1]. Afternoon forecasts suggest temperatures will rise slightly in major cities. Seoul is expected to reach 24 °C, while Daejeon is projected at 26 °C, and Gwangju at 27 °C [1].
Commuters are advised to remain vigilant as the intermittent nature of the rain can lead to sudden changes in road visibility and traction [1].
“Rain will continue on and off until the afternoon.”
The transition from a high-intensity rain-cloud band to scattered showers indicates a stabilizing weather pattern, yet the residual moisture continues to impact infrastructure and safety. The extreme localized rainfall in Jeju highlights the volatility of the region's current weather system, while the modest temperature increases suggest a shift toward more typical late-May conditions.
