**Current short-range forecasts from sources including the Korea Meteorological Administration and AccuWeather point to a daily maximum of 27–28°C for Busan on June 15, consistent with the market’s heaviest trading around those outcomes.** Early June conditions feature increasing solar insolation and typical pre-monsoon warming, with coastal sea breezes from the East Sea moderating peaks below inland values while clear or partly cloudy skies allow efficient daytime heating. Recent observations show highs in the mid-20s under similar regimes, and ensemble guidance shows limited spread around 27–29°C absent any strong frontal systems or unusual subsidence. Resolution will hinge on the official 24-hour maximum recorded by KMA stations, with probabilities reflecting trader assessment of these stable synoptic patterns rather than outlier heat or cooling.
