Trader consensus on Polymarket overwhelmingly favors a high temperature of 21°C or higher in Seoul today, reflecting strong alignment across forecast models from the Korea Meteorological Administration (KMA) and international ensembles like ECMWF and GFS, which project peaks of 24–27°C under a persistent high-pressure ridge delivering clear skies and warm southerly flow. Current observations at 9 AM local time show 18°C with hazy sunshine and rising temperatures, consistent with spring climatology where mid-April highs average 18–20°C but often exceed 21°C during sunny conditions. Realistic challenges include an unexpected influx of cooler maritime air or dense cloud cover stalling diurnal heating, though low-probability scenarios given model agreement; monitor KMA hourly updates through late afternoon for final confirmation against official station measurements.
