Current observations from the Korea Meteorological Administration at Seoul’s central station show a daytime peak of 22°C under partly cloudy skies with light easterly winds and no precipitation, aligning with model consensus that suppressed further warming below typical late-May climatology of 23–24°C. This data anchors the near-certain market-implied probability for a 22°C high, reflecting real-time hourly readings that remained at or below this threshold through afternoon hours. Minor upward revisions remain possible if final daily summaries incorporate slightly higher peripheral station values or if post-sunset adjustments alter the official maximum, though KMA’s standardized methodology makes such shifts unlikely before resolution.
