S. Korea experiences 5th warmest Oct. this year

What happened: South Korea's average temperature reached 15.8 C last month, marking the fifth warmest October since 1973, the Korea Meteorological Administration said. Key numbers: 15.8 C average versus 14.3 C for 1991 to 2022. Seoul hit 30.1 C on Oct. 12, the highest October temperature since 1907. Daily mean fell from 19.8 C on Oct. 18 to 9.8 C on Oct. Why it matters: Warm air from the south from Oct. 10 to 13 pushed the monthly average up, and sharp swings between cold and warm air masses drove wide temperature fluctuations across the peninsula.
