Recent forecast models from agencies like the Korea Meteorological Administration and international ensembles project an October 16 high near 22–23°C for Incheon under mostly cloudy skies, light easterly winds, and modest insolation typical of mid-autumn transition. This range reflects subtle model differences in cloud thickness and boundary-layer mixing, which can shift the daily maximum by 1°C through reduced solar heating or slight warm advection. Trader consensus at 42% for 22°C and 36.5% for 23°C captures this narrow uncertainty band ahead of final observational data, consistent with historical October variability around a 19–20°C climatological mean while noting limited potential for stronger warming or cooling under current synoptic patterns.
