Current forecasts from regional models indicate minimum temperatures in Busan on August 31 will likely range from 24–26°C, driven by persistent summer humidity, a stationary frontal boundary, and limited nocturnal radiational cooling under cloudy, moist conditions. Recent heavy rainfall and thunderstorms through the weekend have sustained elevated dew points near 24–26°C, suppressing temperature drops while steering patterns keep warmer southerly flow in place. This aligns with climatological norms for late August, where historical lows average around 23–25°C absent strong cold advection. Trader consensus, reflected in the 48% implied probability on 21°C or below, appears to incorporate residual uncertainty from model variability and potential for brief clear spells, though official guidance through the Korea Meteorological Administration points to minimal risk of sub-22°C readings without an unexpected shift in synoptic patterns before month-end. Updated model runs and overnight observations over the next 48 hours will provide key data for resolution.
