Korea Meteorological Administration's latest short-term forecast projects Busan reaching a daytime high of 20°C on April 3 under partly cloudy skies with light southerly winds, aligning with international model consensus from ECMWF and GFS ensembles that show tight clustering around this value based on current high-pressure ridge and mild air mass advection. Morning observations confirm steady warming from overnight lows near 10°C, consistent with early April climatology where highs typically range 16–18°C but are elevated today by reduced cloud cover. Trader consensus at 99.6% implied probability reflects this robust data alignment and skin-in-the-game positioning. Realistic challenges include unexpected marine layer persistence dropping it to 19°C or brief clearing pushing to 21°C, though forecast uncertainty remains low with hourly KMA updates monitoring progression through afternoon peak.
