Traders have overwhelmingly converged on a 29°C maximum for Busan today because the latest Korea Meteorological Administration guidance and ensemble model runs project a daytime high near that mark under stable high pressure, clear skies, and light southerly flow that limits additional warming. This outcome aligns with mid-May coastal climatology, where typical highs range 22–25°C yet recent above-normal warmth has raised the baseline without pushing into the next bin. The Gimhae International Airport station reading will settle the market once final observations are posted, though an unexpected shift in steering winds or a late-afternoon sea-breeze reversal could still nudge the peak slightly higher.
