Korea Meteorological Administration's latest short-range forecast indicates a daytime high of 23°C for Busan on May 1 under mostly clear skies following early morning showers, driving trader consensus toward 24°C (36.5% implied probability) and 23°C (35.5%) as the top outcomes. Mild southerly flows from high-pressure ridging elevate temperatures above early-May climatological averages of 20–22°C, with diurnal heating and afternoon insolation potentially pushing peaks to 24°C if skies clear fully by midday. Differentiating factors include ensemble spread among global models like GFS and ECMWF—persistent low clouds or residual moisture could cap at 23°C—along with sea breeze moderation near the coast. Official station observations will resolve the market, with updates through evening refining probabilities amid inherent short-term forecast uncertainty.
