Persistent influence from the North Pacific High continues to advect warm, humid air across the Korean Peninsula, supporting daytime maxima near or above the August climatological average of 29–31°C for Busan. Korea Meteorological Administration short-range guidance for August 13 points to mostly clear skies with a forecast high of 34°C and minimal precipitation, favoring strong solar heating and limited evaporative cooling. Coastal sea breezes and urban heat island effects introduce modest uncertainty in exact peak readings. Recent heatwave advisories and elevated heat indices across southern regions reinforce the potential for temperatures in the low-to-mid 30s, while model spread and possible minor cloud cover keep the market-implied mode centered around 32°C with meaningful probability mass on adjacent bins. Updated KMA and global ensemble runs ahead of the date remain the key near-term catalysts.
