Recent forecasts from agencies like the Korea Meteorological Administration highlight increased cloud cover and shower activity tied to the onset of the East Asian monsoon, which is limiting daytime solar heating and moderating peak temperatures in Seoul. This creates tight uncertainty among 27–29°C outcomes as models show variability in timing and intensity of precipitation over the next 48 hours. High humidity levels near 80% further influence heat indices and evaporation rates, while historical late-June climatology supports typical highs around 27–29°C amid rising seasonal baselines. Updated model runs and official briefings will refine resolution criteria for the exact daily maximum.
