Korea Meteorological Administration observations place Busan's current temperature at 27.3°C with a recent peak of 27.5°C under clear skies and light easterly winds, aligning trader consensus at 99.9% implied probability for a 27°C daily maximum. This reflects short-range forecast models showing hourly peaks of 28–29°C around midday but moderated by the city's coastal location and Korea Strait marine influence, consistent with May climatology where highs average 23–25°C yet occasionally reach 27°C during high-pressure ridges. Strong solar heating and low humidity (33%) support this positioning, though an unlikely late-afternoon wind shift or enhanced sea breeze could cap it at 26°C or nudge toward 28°C before evening cooldown. Final KMA station data resolves the market by midnight.
