**Recent forecasts position mid-30s°C as the most probable range for Busan’s August 25 high.** As of August 23, 2026, extended outlooks from sources like timeanddate.com and AccuWeather indicate sunny to mostly sunny conditions with highs near 37°C (around 98–99°F) on the 24th–25th, following daily maxima of 37–38°C in the preceding days. These align with the market’s leading outcomes—35°C (35.5%) and 36°C (22%)—reflecting trader consensus on typical late-summer peak warmth. Busan’s coastal location on Korea’s southeast provides moderating sea breezes and higher humidity that often cap extremes compared to inland areas, while the North Pacific High sustains warm, stable air masses. Historical August averages hover around 29–31°C daytime highs, but current model runs show a warmer-than-average pattern persisting without significant cloud cover or frontal passages to suppress temperatures. Shorter-range Korea Meteorological Administration guidance similarly points to maxima near 32–33°C in the immediate term, with uncertainty narrowing as the date approaches. Key variables for August 25 resolution include afternoon solar heating, wind speed, and any late-day convection; minor shifts in these could favor 34°C or push toward 37°C. The 34–36°C cluster (combined ~74.5% implied probability) captures the tight consensus around observed trends and short-term model agreement.
