Recent Korea Meteorological Administration forecasts project a daytime maximum of 33°C for Busan on August 19 under mostly cloudy skies and light westerly winds, supported by the lingering North Pacific High advecting warm, humid air masses. This positions 32°C as the market frontrunner at 46% implied probability, with 31°C and 33°C close behind, reflecting typical late-summer patterns where coastal sea breezes often cap peaks slightly below inland guidance. Low precipitation chances and model consensus around 31–33°C explain the tight clustering, though evolving cloud cover and exact timing of any onshore flow introduce uncertainty ahead of final observations. Updated KMA guidance and regional model runs over the next 24 hours remain key variables for traders.
