**Current forecasts from the Korea Meteorological Administration (KMA) and international models indicate a daytime high in Busan on August 8 most likely in the 33–35 °C range under partly cloudy to clear conditions with light easterly winds and minimal precipitation risk.** This consensus underpins the tight market spread between 34 °C (30.0 %) and 35 °C (27.5 %), with 36 °C still receiving meaningful probability (16.5 %). August climatology for coastal Busan shows average daily maxima of 29–31 °C, moderated by sea breezes that often cap temperatures below inland values; however, recent model runs reflect a warmer-than-normal airmass with dew points supporting heat indices several degrees above the dry-bulb reading. Key variables separating the leading outcomes include the strength and timing of the onshore flow, exact location of the official observing site relative to the urban heat island, and any late-day convective cooling. Updated KMA short-range guidance and ensemble spreads released in the next 12–24 hours will be the primary catalyst for shifts in trader positioning ahead of market resolution.
