Current forecast models from the Global Forecast System and regional analyses indicate a peak temperature of 29°C in Busan on September 16, driven by clear skies, northeast winds of 15–20 km/h, and stable atmospheric conditions that limit cloud cover and precipitation. Official monitoring shows afternoon maxima aligning with this level amid typical late-summer patterns, where historical September highs average near 26°C but recent model consensus has shifted upward. Trader positioning at 100% implied probability reflects this alignment, as real-time observations and ensemble runs show minimal divergence. Uncertainties such as localized sea-breeze effects or delayed model updates could still alter the recorded maximum before resolution.
