**Recent KMA forecasts peg the August 11 maximum at 34°C under clear skies and negligible precipitation, aligning closely with the market’s tight clustering around 32–34°C (roughly 79% combined implied probability).** South Korea’s prolonged heatwave, which produced national records above 42°C earlier in August and prompted Seoul’s first severe heatwave warnings, has established persistently high baseline temperatures and elevated soil/atmospheric heat content. This keeps 34°C or 33°C as the most probable outcomes, while minor day-to-day variability in subsidence strength, boundary-layer mixing, or weak onshore flow can easily shift the peak by 1–2°C. Clear conditions favor efficient daytime heating, but any increase in afternoon cloud cover or a subtle wind shift could cap readings nearer 32°C. With resolution just two days away, traders are weighting the latest official guidance and short-range model consensus heavily, resulting in the observed tight distribution around the KMA point forecast.
