Official forecasts from the Korea Meteorological Administration and multiple numerical models project a daytime high of 26°C in Busan on October 9 under a stable high-pressure system centered over the East Sea, producing partly cloudy conditions with light easterly winds and minimal precipitation risk. This aligns with climatological norms for early October in the region, where afternoon temperatures typically peak near 24–26°C before cooler maritime air moderates readings. Trader consensus at near-100% implied probability for exactly 26°C reflects these consistent model outputs and real-time observations through the afternoon. An unexpected late-day surge or localized urban heat effect could push readings to 28°C or above, though current atmospheric stability and wind patterns make such deviations improbable before sunset.
