Korea Meteorological Administration (KMA) short-range forecasts and real-time observations have locked in Seoul's highest temperature on March 28 at 12°C, driving the near-unanimous 99.8% market-implied probability as traders price in confirmed daytime highs amid persistent cool northerly airflow and partial cloud cover typical for late March transitions. Global model ensembles like ECMWF and GFS converge on this narrow outcome, consistent with climatological averages of 11–13°C for the date, supported by low solar insolation from overcast periods earlier in the day. Resolution hinges on KMA's final daily maximum from Seoul station data, usually updated post-midnight; realistic challenges include unexpected clearing skies enabling 1–2°C late-afternoon warming, though current trends make this improbable.
