Recent official forecasts from the Korea Meteorological Administration indicate a daytime maximum of 25°C in Seoul under stable high-pressure conditions and light westerly winds, aligning closely with the market's near-certain pricing for this outcome. Model consensus shows minimal deviation from this value, with clear skies and low humidity limiting further warming despite seasonal norms for mid-May. Historical analogs from similar synoptic patterns confirm that temperatures rarely exceed the forecasted peak without an incoming warm front or significant solar insolation increase. Any realistic shift away from 25°C would require an unexpected late-day temperature spike or revised observational data from central Seoul stations, though current guidance through the evening window shows no such development.
