Recent forecasts from the Korea Meteorological Administration and global models show Seoul's June 14 minimum temperature likely settling between 19–21°C amid partly cloudy skies, light southerly winds, and moderate humidity that limit nocturnal radiative cooling. These conditions create narrow uncertainty bands, with small shifts in cloud timing or boundary-layer mixing able to nudge the overnight low by 1°C. Historical June climatology places typical minima near 18–20°C, but current steering patterns and urban heat effects in Seoul support the market's tight clustering around 20–21°C. Traders weigh the latest model runs against observed trends, as any increase in clear-sky duration would favor lower readings while persistent cloud cover sustains warmer minima.
