Latest forecasts from the Korea Meteorological Administration point to a Seoul high of around 14°C on March 23, fueling trader consensus with 25.5% implied odds for that outcome, closely trailed by 13°C at 21.5% amid model divergence in ECMWF and GFS ensembles. Spring's volatile weather patterns, including lingering Siberian cold air influence and potential southerly winds, create tight differentiation: 16°C or higher (16.4%) reflects upside risk from high-pressure ridging, while 15°C (15%) and 12°C (12.5%) capture ensemble spreads around historical late-March averages of 12-14°C. Urban heat island effects may nudge readings higher, but cloud cover and frontal timing introduce uncertainty, keeping lower outcomes viable. Traders eye today's 12Z model runs for resolution shifts.
