Current ensemble forecasts from the Korea Meteorological Administration and global models place Seoul’s July 11 daytime high near 30–32 °C under lingering East Asian monsoon conditions. Moisture-laden southwesterly flow, variable cloud cover, and scattered showers introduce a roughly two-degree spread across runs, keeping trader probabilities tightly clustered around the 30 °C (20 %), 31 °C (24.5 %), and 32 °C (24 %) bins. A stronger ridge building from the Yellow Sea could push readings toward 33 °C or higher, while an approaching trough or heavier precipitation would favor the lower 29–30 °C outcomes. Historical early-July maxima cluster between 25–30 °C, providing climatological context but little resolution for the specific synoptic setup two days out. Updated KMA guidance and next model cycles remain the key near-term catalysts.
