Recent official forecasts from the Korea Meteorological Administration and global models indicate Seoul's July 27 daytime maximum will likely peak near 31–32 °C under partly cloudy skies with early thunderstorms possible. This consensus, tempered by high humidity and monsoon moisture that can suppress afternoon heating through cloud cover and rainfall, drives the tightly clustered market-implied odds around 30–32 °C. Subtle differences in steering flow and precipitation timing explain the spread: stronger convection or earlier rain lowers peaks toward 30 °C, while clearer breaks allow brief pushes above 32 °C. Historical July baselines near 29 °C and current subtropical ridge positioning further anchor trader assessments of these narrow thresholds ahead of final observational data.
