Forecast models from global and regional meteorological agencies indicate Busan will reach a daily maximum near 30°C on September 8 under partly cloudy skies with moderate northeasterly flow and minimal precipitation, aligning with late-summer climatology for the region where highs typically range 26–29°C. Recent observational data and ensemble runs show consistent daytime warming driven by clear to mostly clear conditions and light winds that limit mixing, supporting trader consensus around this threshold. Minor deviations in actual peak readings could arise from localized sea-breeze effects or slight revisions in the final official report from the Korea Meteorological Administration, though current guidance places the outcome well within the 30°C bin.
