Recent official observations from the Korea Meteorological Administration indicate Seoul's daytime temperatures have peaked near 26°C under mostly clear to partly cloudy conditions with light southwest winds and moderate humidity. This aligns with early-summer climatology for mid-June, where typical highs range 25–28°C before monsoon influences intensify later in the month. Traders have converged on the 26°C outcome at near-certainty levels because real-time station data and short-range model runs show no significant warming trend through the afternoon. A rapid clearing of cloud cover or localized heat advection could still push readings to 27°C or higher before sunset, though current steering patterns and boundary-layer stability make such shifts unlikely.
