The latest Korea Meteorological Administration (KMA) forecast for Busan projects a daytime high of 21°C on April 20 under partly cloudy conditions with light westerly winds and minimal precipitation risk, anchoring trader consensus with 30.5% implied probability on 21°C and 30.0% on 22°C. This tight race among 21–23°C outcomes (collectively ~85%) stems from ensemble model discrepancies—KMA's short-range guidance favors 21°C, while some global models like ECMWF hint at warmer peaks up to 23°C if high-pressure ridging strengthens and cloud cover thins, boosting solar insolation. Recent above-average temperatures, including a market-implied 22°C high on April 18, reflect ongoing spring warming influenced by coastal Tsushima Current effects. Historical April averages hover at 18–20°C; next KMA update by April 19 evening may shift odds amid typical short-term forecast uncertainty.
