Korea Meteorological Administration's latest short-range forecast pegs Busan's May 1 daytime high at 22°C, with a mostly cloudy morning transitioning to partly cloudy afternoon skies, light westerly winds, and just 10% precipitation odds, reflecting a recent cool spell in late April where highs dipped below 20°C. Yet trader sentiment clusters tightly around 23°C (36.5% implied probability) and 24°C (36.0%), driven by ensemble model consensus from GFS and ECMWF suggesting stronger solar insolation under emerging high-pressure influence and warmer air advection, tempered by Busan's coastal sea breeze that often caps peaks. Gimhae Airport hourly guidance tops at 23°C with gusty northwest winds aloft, but afternoon cloud dissipation remains the pivotal uncertainty—persistent clearing could nudge toward 24°C, while marine layer persistence favors 22-23°C. New KMA updates expected midday April 30 may refine this ahead of resolution.
