Recent forecasts from the Korea Meteorological Administration and global models indicate a daily high near 25°C in Busan on October 13, driven by southwesterly flow ahead of an approaching front, with widespread cloud cover, showers, and humidity near 80% limiting solar heating. Afternoon temperatures have hovered around 23–24°C in real-time observations amid light rain, aligning with historical mid-October averages of 22–24°C and reducing upside risk for 26°C or higher. Market-implied odds reflect this consensus while assigning modest probability to a brief 26°C spike if breaks in cloud cover allow additional warming before the front arrives.
