Recent forecasts for Busan indicate a minimum temperature on August 27 likely in the mid-20s Celsius, with models showing overnight lows near 24–27°C amid partly cloudy conditions and a 60% chance of thunderstorms. Persistent influence from the North Pacific high has sustained elevated heat into late August, pushing temperatures above seasonal averages, though increasing cloud cover and potential rain overnight could moderate the low. Model consensus from sources like the Korea Meteorological Administration highlights uncertainty in exact minimums due to variable steering winds and localized cooling effects from precipitation. Historical climatology places typical August 27 lows near 23°C, but current atmospheric patterns favor warmer outcomes. Traders are closely watching updated model runs and official briefings for shifts in overnight conditions that could resolve the tight spread between 26–28°C.
