Recent official observations from the Korea Meteorological Administration confirm peak hourly readings reaching 28°C in Busan on October 12, aligning with trader consensus at near-100% implied probability for that exact high. Model forecasts had projected daytime maxima near 25–26°C under partly cloudy conditions with easterly winds, yet localized warming and clear intervals pushed actual values higher, consistent with October climatology for the region. The market-implied odds reflect this verified data rather than projections alone. A realistic challenge would require post-event verification or measurement adjustments showing a final daily maximum of 27°C or 29°C, though such revisions remain unlikely given the dense station network and consistent readings.
