Recent forecasts from models like those referenced by the Korea Meteorological Administration indicate Seoul's June 15 daytime maximum will likely peak near 29–30 °C under partly cloudy skies and light southwesterly winds, keeping trader consensus centered on the narrow 28–30 °C band. Subtle differences in these outcomes hinge on variables such as morning cloud thickness, which can suppress solar heating by 1–2 °C, versus clearer intervals that allow urban heat-island effects to push readings higher; surface humidity and boundary-layer mixing also modulate how much heat accumulates before afternoon convection develops. With June climatology showing typical highs of 26–28 °C and early-summer monsoon moisture beginning to increase, the market-implied odds capture genuine uncertainty in the final observed maximum at the official station, especially as updated model runs and evening observations on June 14 refine the thermal profile.
