Trader consensus on Polymarket has locked in a 100% implied probability for Seoul's highest temperature reaching exactly 13°C on March 27, driven by official observational data from the Korea Meteorological Administration (KMA), which recorded a maximum of 13.0°C at key stations like Jongno, under cool spring conditions with highs in the low teens amid lingering cold air masses and light winds. Preceding forecast models from KMA and ECMWF aligned closely with this outcome, showing minimal deviation after morning soundings confirmed stable atmospheric profiles unfavorable for warming. Realistic challenges would require post hoc data revisions from quality control—rare for settled daily maxima—or disputes over measurement sites, but KMA's standardized protocols and historical accuracy in urban Seoul readings make shifts improbable ahead of final reporting. Watch for KMA's daily summary release confirming the record.
