Latest numerical weather prediction models from the Korea Meteorological Administration and global ensembles show a consensus minimum temperature of 16–17°C for Seoul on June 10 under mostly clear skies, driving the tight clustering of market-implied odds around those values. Radiational cooling overnight in the absence of significant cloud cover or strong winds favors the lower end of the range, while any increase in humidity or light southerly flow could push readings toward 18°C. Early-June climatology places typical overnight lows near 15–17°C, providing a stable baseline against which current guidance aligns closely. The final hours before dawn on June 10 remain the key uncertainty window, as small shifts in boundary-layer moisture or timing of any residual frontal passage could alter the observed minimum by 1°C.
