Rain, falling temperatures forecast across South Korea for Oct 5 holiday
Version 2: Two more outlets joined the forecast — Asia Economy with city-by-city temperatures for Oct 5 and Korea Economic Daily with a headline-only match — while a Newsis article published under a weather headline again carried text about financial-sector hacking rather than the weather.
In short
South Korea’s weather agency forecast rain for much of the country early on Monday, Oct 5, a substitute holiday and the last day of the National Foundation Day weekend, with showers in the central region, Jeolla, parts of North and South Gyeongsang inland and Jeju between the early hours and the morning. Morning lows were put at 11–17C and daytime highs at 19–25C, about 5C below Oct 4, with cold northern air and strong winds from the afternoon making it feel colder. Gusts of about 55 km/h were forecast nationwide and about 70 km/h in mountainous areas from Oct 5 until the morning of Oct 6.

The Korea Meteorological Administration forecast that Monday, Oct 5 — a substitute holiday and the last day of the National Foundation Day weekend — would be mostly cloudy, with rain in the central region and Jeolla from the early hours to the morning, Yonhap and Asia Economy reported. Cold air from the north was expected to arrive in the afternoon, bringing stronger winds and making it feel colder, and the agency advised attention to health amid the sharp change in temperature. Rain was expected to start on the night of Oct 4 in the Seoul metropolitan area, northern Gangwon inland, South Chungcheong and northwestern North Jeolla, then spread overnight and in the morning to the central region, Jeolla, northwestern North Gyeongsang inland, western South Gyeongsang inland and Jeju.

Morning lows on Oct 5 were put at 11–17C and daytime highs at 19–25C, with daytime temperatures about 5C lower than on Oct 4. Asia Economy listed city forecasts, giving morning lows and daytime highs of 15C and 20C in Seoul, 15C and 19C in Incheon, 12C and 19C in Chuncheon, 15C and 22C in Gangneung, 14C and 21C in Daejeon, 15C and 23C in Daegu, 15C and 20C in Jeonju, 16C and 22C in Gwangju, 17C and 24C in Busan, and 19C and 22C in Jeju.

Expected rainfall was 5–30 mm for Incheon, northern Gyeonggi and northern Gangwon inland; 5–20 mm for Gangwon inland and mountainous areas excluding northern Gangwon inland; and 5–10 mm for Seoul, southern Gyeonggi, Ulleungdo and Dokdo. Daejeon, Sejong, South Chungcheong and North Chungcheong were expected to receive around 5 mm. Yonhap put Jeolla, Gwangju and South Jeolla, western South Gyeongsang inland, northwestern North Gyeongsang inland and Jeju at under 5 mm, while Asia Economy said 5 mm. Where rain fell, gusts, thunder and lightning were possible, with hail under 0.5 cm across parts of the central west coast, northern Gyeonggi inland and northern Gangwon inland, and Asia Economy advised care for crops. Yonhap forecast gusts of about 55 km/h nationwide and about 70 km/h in mountainous areas from Oct 5 to the morning of Oct 6. [ 1 , 3 ]
Two other outlets headlined the same weather but published different material underneath. Newsis led with the holiday’s last day and the afternoon temperature drop, while its article text dealt with hacking and customer data leaks in the financial sector. Korea Economic Daily’s article, headlined on nationwide rain on Oct 5, carried items on the prime minister’s remarks about structural reforms, the police chief’s comments on National Hangeul Day and a dispute over vehicle protests. The documents do not explain either mismatch, and neither article reports weather damage or disruption. [ 2 , 4 ]
Why it matters
The forecast covers the final day of a holiday weekend, when travel and outdoor plans are concentrated, and it warns of a temperature swing of about 5C along with strong winds, which the weather agency said people should take into account for their health. The documents describe a domestic weather event and report no damage or disruption, and give no indication of consequences beyond South Korea.

Still unclear
- A Newsis article published under a weather headline carried body text about hacking and customer information leaks in the financial sector. The article text does not match the outlet’s weather headline or the other documents and is not about this event; the documents do not explain the mismatch.
- Korea Economic Daily’s article, headlined on nationwide rain on Oct 5, carried items on the prime minister’s remarks about structural reforms, the police chief on National Hangeul Day and a dispute over vehicle protests. Those items are not about this event and the documents give no reason for their appearance under the weather headline.
- Yonhap says Jeolla, Gwangju and South Jeolla, western South Gyeongsang inland, northwestern North Gyeongsang inland and Jeju will see under 5 mm of rain, while Asia Economy says 5 mm. The two forecasts for the same regions differ slightly; the documents do not reconcile them.
- Which specific locations are expected to see thunder, lightning and small hail. Yonhap says such conditions are possible in some places among the affected regions without naming them.
- Whether the rain, wind or temperature drop will cause damage or disruption. None of the documents reports impacts from the weather.
