Rain has largely stopped across South Korea, with clear skies expected nationwide starting midday on Sunday [1].

This shift in weather comes as the country prepares for the Children's Day holiday, bringing a significant temperature increase that affects commuting safety and clothing choices for millions of residents.

While most areas are clearing, rain clouds remain in parts of Gangwon Province [1]. Weather caster Jung Su-hyun said that although the rain has mostly ceased, some regions still face sporadic precipitation. She said that roads may be slippery in these areas and advised commuters to prioritize traffic safety [1].

Temperatures are rising sharply. The daytime high in Seoul is expected to reach approximately 20 °C [1]. This represents a climb of roughly five °C compared to the previous day [1]. Jung said that temperatures will rise further on Monday, which is Children's Day, providing favorable conditions for outdoor spring activities [1].

Despite the sunshine, the forecast includes warnings for strong winds across the country and rough seas [1]. Residents are advised to prepare for large temperature swings between day and night to avoid illness.

Regional forecasts specifically highlight conditions in Seoul, Gangwon Province, northern Chungcheong, and northern Gyeongsang [1]. The combination of high winds and lingering moisture in the north creates a varied weather landscape for the start of the week [1].

“Seoul daytime temperature expected to be about 20 °C”

The rapid temperature swing and coinciding strong winds indicate a volatile transition into spring weather. For the public, this necessitates a shift from rain gear to layered clothing to manage the five °C jump in temperature, while the rough sea conditions may impact coastal shipping and fishing activities heading into the holiday.
