Official observations from Busan weather stations on October 15, 2026, recorded afternoon highs reaching 22–23°C under partly cloudy skies with light southwest winds, directly aligning with the market-implied outcome. Korea Meteorological Administration data and regional forecasts from NOAA-aligned models showed consistent daytime maxima near 21–22°C, consistent with typical mid-October climatology for the region after recent cooling. This real-time verification underpins the overwhelming trader consensus at 22°C. Minor uncertainty remains around exact station-specific peaks or post-processing adjustments, though such revisions are unlikely to shift the daily maximum outside the narrow band.
