Recent KMA and international model runs show Busan likely reaching a daily maximum near 29–30 °C on 16 August under lingering influence of the North Pacific High, yet increasing cloud cover and possible showers could suppress insolation enough to cap readings at 27–28 °C. Coastal sea-breeze effects and higher humidity typical of mid-August further narrow the range, producing closely matched market odds across 26–29 °C. Updated short-range guidance from the Korea Meteorological Administration over the next 24–48 hours will clarify whether the high-pressure ridge strengthens or yields to a passing disturbance, directly shifting implied probabilities for each threshold.
