Korea Meteorological Administration (KMA) observations confirm Busan's highest temperature reached 23°C around mid-afternoon on April 11, peaking at approximately 73°F per hourly records from local stations, under mostly sunny skies and mild southerly flows. This aligns with pre-dawn forecast consensus from KMA short-range models and international agencies like the UK Met Office, which projected a daytime maximum of 23°C amid high-pressure ridging and above-average spring warmth—historical early-April highs average 17–18°C. With sunset approaching and evening readings dropping to the mid-teens, trader consensus reflects near-certainty, backed by real-money positions. A realistic challenge would require an anomalous late-day heat burst or upward revision in final KMA data, both improbable given declining solar insolation and increasing cloud cover.
