Current observational data and forecast models from agencies monitoring East Asian weather patterns show Busan temperatures peaking near or below 24°C on September 27, driven by persistent cloud cover, high humidity near 90%, light variable winds, and occasional drizzle that limits daytime heating. These conditions align with late-September climatology for the region, where average highs hover around 24–25°C amid transitional monsoon influences. Trader consensus at 100% for 24°C or below reflects this strong alignment across multiple model runs, with minimal divergence expected. A rapid clearing of skies or unexpected warm-air advection could push readings higher, though such shifts remain unlikely given the stable pressure field and ongoing overcast regime.
