Recent forecasts for Busan highlight uncertainty in peak temperatures for August 16, driven by variable cloud cover, potential heavy rain, and steering patterns that could limit daytime heating below typical August averages of 29–31°C. Official guidance from the Korea Meteorological Administration projects a possible high near 33°C under mostly cloudy skies, while shorter-range models from sources like timeanddate indicate cooler conditions around 26°C amid widespread precipitation and overcast skies that reduce solar radiation. These divergences, combined with Busan’s coastal humidity and monsoon influences, explain why traders assign nearly equal weight to 27°C and 28°C outcomes, with nearby probabilities reflecting the narrow band where small shifts in rainfall timing or wind could tip the daily maximum. Updated model runs and agency briefings in the next 48 hours will likely narrow this range.
