**Trader sentiment for Busan's highest temperature on August 22, 2026, centers on 32°C as the most likely outcome (39.5% implied probability), followed closely by 33°C (29%), reflecting current forecast consensus around 31–33°C.** Official guidance from the Korea Meteorological Administration and extended models shows a high near 31°C under mostly cloudy skies with isolated thunderstorms and light rain possible late in the day. This pattern aligns with the post-heatwave transition in mid-to-late August, when the East Asian monsoon brings increased moisture, cloud cover, and convective activity that limits solar heating and caps afternoon peaks. Busan’s coastal setting adds sea-breeze moderation, further reducing the chance of extremes seen earlier in the month. A record-setting heatwave peaked in early August with temperatures exceeding 40°C inland, but alerts have eased as rain and cloudier conditions dominate. Updated short-range forecasts emphasize precipitation probabilities of 30–60% on the 21st–22nd, which historically suppresses daily maxima by 1–3°C relative to clear-sky scenarios. While model runs still allow for brief clearing that could push readings to 33–34°C, the probability mass clusters tightly around 32°C given the timing of any showers and persistent humidity. New KMA updates or refined model guidance in the next 24–48 hours remain the key near-term catalysts for shifts in these market-implied odds.
