Recent official forecasts from Chinese meteorological sources and international models indicate a minimum temperature in Jinan around 18–20°C on September 28, driven by a shift from southerly to northerly winds under mostly cloudy to overcast skies with a 55% chance of light rain in southern districts. These conditions limit radiational cooling overnight while urban heat effects in the city center moderate lows relative to outlying areas. Trader consensus clustering near 17–18°C reflects this narrow range, with differentiation hinging on exact precipitation timing and wind speed, which influence boundary-layer mixing and surface heat loss. Updated model runs and observational data through the night will refine the final recorded minimum before market resolution.
