Current meteorological forecasts for Busan on June 7 converge on a daily maximum of 24°C, driving the near-certain market positioning. Early June places the region in a transitional shoulder period, with climatological normals for the Korean Peninsula typically ranging 22–26°C amid moderate onshore flow and limited daytime heating from partly cloudy conditions. Ensemble guidance from agencies such as the Korea Meteorological Administration shows consistent model agreement on this narrow peak, without significant warm advection or clear-sky amplification that would push readings higher. Official station measurements, which resolve the market, are expected to align closely with these projections. Only an unforecasted localized heat burst or instrumentation variance could realistically shift the outcome.
