Recent Korea Meteorological Administration (KMA) guidance and supporting global ensemble models show daytime maxima in the Seoul-Incheon corridor likely peaking near 33–34 °C on 3 August, driven by persistent summer monsoon moisture, light winds, and modest insolation under variable cloud cover. Trader sentiment clusters around these bins because model runs differ mainly on the timing and coverage of afternoon convection, which can shave 1–2 °C from peak readings, versus clearer intervals that allow greater boundary-layer heating. Historical August climatology places the area average near 31 °C, so the current outlook reflects a modest positive anomaly without the extreme ridging needed for 35 °C-plus outcomes. Updated KMA short-range forecasts and next model cycle releases will refine the precise maximum and shift implied probabilities accordingly.
