Visitors to Daejeo Ecological Park in Busan’s Gangseo District strolled through fields of fully bloomed pampas grass on September 10, soaking in the autumn scenery as seasonal weather shifts bring sharp temperature swings across South Korea.
Chilly Mornings, Mild Afternoons Forecast for September 11
The Korea Meteorological Administration (KMA) forecasts a cold start on September 11, particularly in the central region, where morning lows will dip to around 10°C (50°F). Daytime highs are expected to recover to seasonal norms, reaching 24–29°C (75–84°F), creating daily temperature gaps of 10–15°C in many areas.
Cold, Dry Northerly Winds Drive Temperature Extremes
A stream of cold, dry air from the north will sustain this pattern for the coming days: crisp, chilly mornings followed by noticeable afternoon warming. The KMA projects nationwide morning lows of 10–20°C and daytime highs of 24–29°C.
Central and Inland Southern Regions Below Seasonal Averages
Morning temperatures in the central region and southern inland areas will run 3–5°C below the seasonal average. Mountainous parts of Gangwon Province — including Inje, Jeongseon, Yeongwol, and Taebaek — are expected to see lows hovering around 10°C.
