Recent Korea Meteorological Administration forecasts indicate a daily maximum temperature of 25°C in Seoul under clear skies and light southerly flow, driving the market-implied probability for that exact outcome above 99%. This aligns with typical mid-May climatology for the region, where diurnal heating peaks in the mid-twenties Celsius absent strong synoptic forcing or moisture influx. Model consensus shows minimal spread in guidance through the afternoon, with resolution hinging on the official recorded high at the Seoul station. A sudden increase in cloud cover or localized cooling could cap readings below this threshold, while unanticipated warm advection from the south remains the primary low-probability pathway to 26°C or higher.
