Trader sentiment for Seoul's March 24 high temperature remains tightly contested around 12-14°C due to converging yet divergent global model ensembles, with the Korea Meteorological Administration's latest forecast favoring 13°C amid a building high-pressure ridge fostering mild conditions. Differentiating factors include subtle variations in predicted low-level winds—northerly flows in some ECMWF runs capping peaks at 11-12°C by enhancing mixing and cloudiness, versus GFS southerly biases lifting toward 15°C—and urban heat island amplification under clear skies. Recent March 23 observations near 11°C align with climatological norms of 10-13°C for late March, underscoring low forecast volatility but razor-thin resolution margins.
