Trader consensus overwhelmingly favors 11°C as Seoul's highest temperature on March 21, driven by the latest forecasts from the Korea Meteorological Administration (KMA) and ECMWF ensemble models, which converge on a daytime high of 11°C amid a stable high-pressure system and light northerly winds suppressing warming. Historical March 21 averages hover around 12°C, but current synoptic patterns—cool air mass advection and low solar insolation from partial cloud cover—align with this cooler outlook, corroborated by GFS and UKMO runs showing minimal deviation. Realistic challenges include an unanticipated southerly wind shift or frontal passage accelerating mixing of warmer air aloft, potentially pushing peaks to 12–14°C, though model spread remains tight at ±1–2°C.
