Korea Meteorological Administration observations confirm Busan reached a daily high of 18°C around midday on April 29, with persistent cloud cover and light southerly winds limiting solar heating thereafter, aligning with short-term forecast models projecting a maximum in the 18–19°C range amid a broader chilly pattern across southern Korea (morning lows 11–12°C, daytime highs 15–21°C regionally). This trader consensus reflects real-time station data from Gimhae Airport and urban sites, where temperatures peaked early before a stabilizing cool air mass took hold, consistent with April climatology (historical average high ~19°C). An improbable late-afternoon clearing could challenge this by enabling brief solar-driven warming to 19°C, but current infrared satellite imagery and model ensembles indicate low likelihood ahead of evening resolution. Final KMA daily summary expected post-midnight.
