Trader consensus overwhelmingly favors a Seoul high temperature of 11°C on March 21, driven by the latest ensemble forecasts from the Korea Meteorological Administration (KMA) and global models like ECMWF, which consistently project a daytime maximum around 11°C under persistent cool northerly flows and light cloud cover. Historical March data for Seoul shows average highs of 10-12°C, with recent observations confirming chilly conditions following a cold snap, aligning with minimal diurnal warming. This positioning reflects low forecast uncertainty at short range, but a realistic challenge could arise from unexpected southerly wind shifts or frontal breakdown introducing warmer air masses, though upper-air patterns make this improbable below 5% odds.
