Current short-range forecasts from the Korea Meteorological Administration and global models indicate a daily maximum of 26–28°C in Busan on June 16, driven by southerly flow ahead of the East Asian monsoon onset, mostly cloudy skies, and moderate humidity that moderates peak heating. These conditions align with climatological norms for mid-June, where average highs reach about 26°C. The market's leading 28°C outcome at 37.5% reflects trader assessment of potential model spreads and brief clearing that could push readings 1–2°C above guidance, while 29°C at 22.5% captures upside risk; lower outcomes remain less favored given the absence of strong high-pressure ridging. Updated KMA briefings and ensemble runs over the next 48 hours will refine probabilities ahead of resolution.
