About this Market

Recent forecasts from the Korea Meteorological Administration and global models indicate Incheon highs of 23–25°C on September 30, with 24°C and 25°C outcomes nearly tied in trader sentiment due to uncertainty in afternoon timing. A southwesterly flow ahead of an approaching trough supports modest warming above seasonal norms, while increasing cloud cover and scattered showers developing midday to evening could cap peak readings near 24°C through evaporative cooling and reduced insolation. Ensemble guidance shows limited spread, with resolution hinging on whether showers arrive before or after the daily maximum. Updated KMA briefings and refined model runs over the next 48 hours will likely clarify the threshold.
