South Korea expects scattered rain and showers across the country this Thursday, with high sea waves forecast for the South Sea and Jeju [1, 2].
The weather pattern combines late-summer heat with the indirect influence of Typhoon Saudel, creating volatile conditions for coastal regions and urban centers.
In Seoul, temperatures were recorded at 25.3°C [2] during the early morning broadcast. The midday high is projected to reach 32°C [1], though some reports suggest a slightly lower peak of 31°C [3].
Rainfall will vary significantly by region. Northern Gyeonggi and Gangwon provinces are expected to receive between five and 20 mm of rain through the afternoon [1]. The southern coast and Jeju Island face heavier precipitation, with forecasts predicting up to 60 mm [1]. Other reports indicate rainfall could reach as high as 80 mm in the Yeongnam region [3].
"Today, rain or showers will fall in various places amidst the late summer heat," said YTN weather caster Won Yi-da [1].
The precipitation is being driven by a north-bound low-pressure trough and the residual effects of Typhoon Saudel [1, 2]. These systems are generating not only the showers, but also elevated wave heights in the South Sea and waters surrounding Jeju [1].
Won Yi-da said the late-summer heat will persist in the capital, noting that Seoul's temperature will climb to 32°C during the day [1].
“Rain or showers will fall in various places amidst the late summer heat.”
The convergence of a low-pressure trough and the indirect effects of Typhoon Saudel illustrates the instability of the late-summer transition period in East Asia. While the capital experiences lingering heat, the southern regions face significant precipitation risks, necessitating caution for maritime activities in the South Sea and Jeju waters.
