Recent forecasts from the Korea Meteorological Administration and global models indicate daytime highs in Seoul on June 16 likely reaching 29–32 °C under mostly clear to partly cloudy conditions, with light southerly winds and moderate humidity ahead of the East Asian monsoon onset. Trader consensus clustering on 28–29 °C reflects model agreement on limited cloud cover and no significant frontal passage, tempered by uncertainty in afternoon convective development that could cap peaks near 27 °C or allow brief spikes above 30 °C. Historical June climatology shows typical maxima near 27–28 °C, but current warm advection from the south supports the slight upward bias in near-term guidance. Updated model runs and official KMA briefings over the next 48 hours will refine resolution thresholds.
