Recent Korea Meteorological Administration forecasts for August 20 project a maximum near 33°C under mostly cloudy skies with limited afternoon precipitation, yet persistent cloud cover and possible showers introduce variability that could cap the daily high at 29–30°C. Incheon observations, used for official Seoul-area records, typically track slightly cooler than inland sites amid marine influence and urban heat effects. Traders weigh these factors against typical late-August climatology, where highs average 29–31°C, resulting in tightly matched probabilities for 29°C and 30°C outcomes. Updated model runs and KMA briefings over the next 48 hours will likely refine steering patterns and instability, directly influencing resolution around the 32–33°C thresholds.
