Recent short-range forecasts from the Korea Meteorological Administration indicate a daytime maximum near 30°C at Busan’s Gimhae International Airport under clear skies, southerly flow, and moderate insolation. This setup aligns with observed morning readings around 25°C and supports the market’s 90% implied probability for a 30°C high. Minor model spreads allow limited upside to 31°C, reflected in the 10% odds, while stronger warming would require unexpected wind shifts or reduced cloud cover not currently projected. Mid-May climatology for the region shows typical highs of 22–24°C, making today’s conditions slightly above average but well within historical variability for the station. Afternoon observational updates will confirm resolution thresholds.
