Southwest Korea Faces Frost Risk as Diurnal Temperature Swing Impacts Crops and Prices

Southwestern Korea is forecast to see temperatures near seasonal norms this weekend in Gwangju and the Jeollanam-do region, but with a pronounced day-to-night temperature swing that could exceed 10 degrees Celsius.

For Saturday, inland Jeollanam-do is expected to have morning lows between -2°C and 3°C, with daytime highs ranging from 11°C to 15°C. Skies may be partly cloudy early, turning generally sunny in the afternoon.

On Sunday, morning temperatures are projected to be between 1°C and 5°C, with daytime highs of 10°C to 15°C. The sky is expected to be mostly cloudy, clearing gradually into the night.

Overall, the pattern is a high near the mid-teens Celsius and a notable diurnal range, which can affect daily life and health, particularly for those sensitive to temperature shifts.

The Gwangju Regional Meteorological Administration warned that inland areas could see frost or ice in the mornings, and that the sharp temperature changes warrant careful health management and attention to potential frost damage to crops.

Beyond Korea, such frost risk in a key agricultural region can influence local crop yields and vegetable prices, with potential ripple effects on supply chains and markets that rely on East Asian agricultural production and related logistics.

Gwangju is a major city in the southwest, and Jeollanam-do is the adjacent coastal province; the forecast comes from Korea’s regional meteorological office under the national weather agency. U.S. readers may watch for any downstream impacts on commodities and prices tied to East Asian crops and regional shipping schedules.
