Korea to be mild and sunny nationwide; Gangwon heavy snow, east coast rain.

Tomorrow across the Korean Peninsula is expected to be mostly sunny and mild, with dust dispersing and spring-like conditions returning.

However, the mountainous areas of Gangwon Province in the northeast are forecast to see continued heavy snowfall, with accumulations of more than 20 centimeters. The snow is described as heavy and wet, likely to pile up in a short period.

The east coast is also set to receive some rain in the afternoon tomorrow.

In terms of temperatures, Seoul is forecast to begin around 2°C in the morning and rise to about 12°C by midday. Gwangju should reach roughly 14°C at the warmest point of the day.

After tomorrow, temperatures are projected to stay just above the seasonal average with little variation for a while.

A fresh northeast air mass is expected to push dust away, improving air quality nationwide to good-to-normal levels.

Why this matters beyond Korea: U.S. readers should note that regional weather in Northeast Asia can influence transportation, energy demand, and logistics tied to Korea’s large electronics and semiconductor industries, as well as tourism in ski areas that rely on winter snowfall.

Context for readers: Gangwon Province is a mountainous region in eastern Korea that hosts major ski resorts and regional transport routes, meaning heavy snow can disrupt roads, rail, and air travel and potentially affect cross-border shipments and supply chains.

Overall, the forecast points to mild, clear conditions for most of the country with notable disruptions only in the mountain areas, alongside improving air quality as dust is pushed away by seasonal winds.
