Trader consensus has converged on a 28°C daily maximum in Busan today, reflecting real-time surface observations from Korean Meteorological Administration stations that recorded a peak near that threshold under predominantly cloudy, northeasterly flow. Model guidance from GFS and regional analyses showed limited diurnal heating due to marine influence and moisture, aligning closely with the observed 24–27°C range before the final reading settled at 28°C. This outcome sits slightly above the long-term September climatological high of roughly 26°C. Only an unexpected late-afternoon spike or post-hoc station data revision could alter resolution, though current verification timelines make such shifts improbable.
