Korea Meteorological Administration (KMA) observations confirm Seoul's highest temperature on April 16 reached 27.3°C at the official station, locking in the market-implied 100% probability for 24°C or higher amid an unseasonal early-summer heatwave. Mostly clear skies and a persistent high-pressure system drove daytime highs well above the April climatological average of 18°C, aligning with KMA short-range forecasts of 23–27°C and AccuWeather models. Trader consensus reflects this verified data from real-time monitoring, with large daily temperature swings noted in recent KMA updates. Realistic challenges are negligible post-observation, barring rare data revisions, as final daily maximums are typically set by evening.
