Recent forecasts from multiple models indicate Busan’s overnight minimum on August 26 will likely settle near 24–28 °C, with coastal moderation from the East Sea and light northerly winds limiting radiative cooling. Trader consensus clusters around 24 °C because ensemble guidance shows early-morning readings in that range under mostly clear to partly cloudy skies, while slight differences in cloud cover or wind speed could push the low a degree lower or hold it near 25–26 °C. The spread between 22 °C or below and higher outcomes reflects typical late-summer uncertainty in nocturnal boundary-layer mixing and any scattered showers that might suppress cooling, rather than any major synoptic shift. Updated model runs expected later today will refine the precise threshold for market resolution.
