Traders overwhelmingly back 13°C (99.9% implied probability) as Seoul's highest temperature on March 27, driven by official observations from the Korea Meteorological Administration (KMA) confirming a daytime peak of 13°C under a stable cool air mass. Northerly winds and a blocking high-pressure ridge over the Korean Peninsula limited solar heating and convective activity, aligning with consensus from KMA's short-range forecast models and global ensembles like ECMWF and GFS. March climatology supports this, with historical highs averaging 11–13°C amid typical spring variability. Scenarios challenging this—such as an unforecast rapid warm advection or station data correction—are highly improbable given KMA's calibrated surface measurements, with final verification reports due within hours.
