Korea Meteorological Administration (KMA) short-range forecasts confirm a daily high of 21°C at Gimhae International Airport—the official resolution station for Busan—under partly cloudy skies with light winds and 10-20% precipitation odds, anchoring trader sentiment at virtual certainty for this outcome. Current observations show mid-afternoon temperatures nearing 18°C amid hazy sunshine, aligning with ensemble model consensus and recent mild spring patterns that have pushed April highs above the 17°C climatological average. While inherent forecast uncertainty persists, scenarios challenging 21°C—such as unexpected clearing for enhanced solar heating to 22°C or station microclimate variations—appear improbable given tight model agreement. KMA's end-of-day observations will seal resolution.
