Trader sentiment clusters around 13-16°C highs for Seoul on March 23, with 16°C or higher edging out at 26% implied probability, propelled by the Korea Meteorological Administration's latest forecast of 14-16°C daytime peaks under building high pressure and mild southerly flows. Differentiating factors include ECMWF and GFS model ensembles showing divergent cloud cover—thinner cirrus boosting insolation for 15-16°C versus thicker stratus capping at 13-14°C—and jet stream undulations that could usher cooler Siberian air. Historical late-March norms hover near 12-13°C, but recent solar forcing and reduced precipitation risk elevate warmer odds, though diurnal timing and urban heat islands add resolution uncertainty.
