Recent KMA and model guidance for Busan highlights anticipated daytime showers and increased cloud cover on July 25 that should cap solar heating and keep maximum temperatures near 30–33 °C, aligning with the closely matched market-implied probabilities for 33–35 °C. The East Asian summer monsoon typically brings humid southerly flow and frequent precipitation to the southern coast, while persistent sea breezes from the Korea Strait further moderate coastal maxima relative to inland sites. Minor differences among leading outcomes hinge on the exact timing and intensity of convective rain, any breaks in cloud cover, and subtle shifts in steering winds that could allow brief periods of stronger insolation. Updated short-range KMA forecasts and ensemble runs over the next 48 hours will likely refine these thresholds ahead of resolution.
