Latest Korea Meteorological Administration medium-range forecasts and global models like GFS and ECMWF show Busan highs clustering around 22–24°C on May 7, reflecting trader consensus with implied probabilities evenly split across 21–25°C outcomes. This tight spread stems from model agreement on mild southerly flows and light southwest winds (8–12 mph) fostering seasonal norms, but uncertainty arises from divergent cloud cover projections—some runs indicate partial clearing for peaks near 25°C, while others forecast late showers and high clouds capping at 21–22°C. Coastal sea breezes and diurnal timing further differentiate exact maxima, with historical May averages at 22°C providing baseline context. Daily KMA updates expected by May 6 could refine ensemble guidance.
