Recent forecasts from multiple models indicate a high near 29–30°C for Incheon on August 28, consistent with trader emphasis on the 30°C and 31°C outcomes. Persistent influence from the North Pacific high-pressure system sustains warm, humid air across the region, while an approaching disturbance and increasing cloud cover introduce modest cooling potential through scattered showers and reduced insolation. Historical climatology shows late-August maxima averaging near 30°C, with day-to-day variability driven by the exact timing of convective activity and wind shifts. Model consensus on peak values remains tight because steering patterns and precipitation timing carry residual uncertainty, keeping probabilities clustered between 29°C and 31°C rather than favoring extremes.
