Ongoing heatwave conditions across South Korea, including heatwave warnings covering Busan from the Korea Meteorological Administration, support market-implied odds clustering around 34–35°C as the likely daily maximum on August 5. Persistent high pressure, clear skies, and light easterly winds favor strong daytime solar heating, while Busan’s coastal position introduces moderating sea-breeze effects that typically cap peaks a few degrees below inland sites like Yangsan. Recent observations show nearby areas reaching the high 30s, with model consensus pointing to afternoon maxima near 34–35°C under these stable patterns; any late-day thunderstorm development or stronger onshore flow could trim the peak toward 33°C, whereas continued clear conditions could push it to 36°C. Traders weigh these variables against historical August baselines of 29–31°C and the resolution criteria tied to official KMA station readings.
