Recent forecasts from GFS and similar models indicate clearing skies and northwesterly flow over Busan on October 14 following thunderstorms on the 13th, with dry continental air and 10–15 km/h winds limiting daytime heating. Coastal moderation from the East Sea and rapid post-frontal drying support a daytime maximum near 20–22°C, aligning with trader emphasis on the 21°C and 22°C outcomes. Model spreads arise mainly from slight differences in wind timing and boundary-layer mixing, while historical mid-October averages near 21°C provide context. Updated short-range runs closer to the date will refine the peak temperature for market resolution.
