Official observations from the Korea Meteorological Administration confirm daytime maxima reaching 30°C in Seoul on June 17 under clear to partly cloudy skies and southerly flow, aligning precisely with the market's 100% implied probability on that outcome. This consensus draws from real-time surface measurements, urban heat-island effects amplifying readings by 1–2°C above regional baselines, and model guidance showing limited afternoon mixing amid moderate humidity. Historical June averages near 27–28°C provide context for the slight positive anomaly driven by a high-pressure ridge. Only an unexpected late-day frontal passage or measurement revision could realistically shift the recorded high, though current conditions make such scenarios improbable before resolution.
