Recent forecasts from models and the Korea Meteorological Administration indicate a typical early-summer pattern for coastal Busan, with daytime highs likely peaking near 28–30°C amid moderate humidity and variable cloud cover. Sea breezes from the East Sea and potential scattered showers could cap maximum temperatures, creating tight differentiation between 29°C and 30°C outcomes. Ensemble guidance shows minor spread due to uncertainties in afternoon convective timing and wind strength, while climatological baselines for mid-June average around 24–26°C. Traders weigh these variables against updated short-range model runs expected before resolution, reflecting genuine forecast uncertainty at the 45–55% probability range for the leaders.
