Current forecasts from meteorological models indicate a mild overnight minimum for Jinan on September 22, with consensus lows centering near 17–20 °C under mostly clear skies and light southerly winds that limit cloud cover and enhance radiative cooling after a daytime high near 30–32 °C. This setup reflects typical early-autumn conditions in the North China Plain, where decreasing solar insolation and dry air masses promote stronger nocturnal temperature drops than midsummer patterns, though model spreads and subtle variations in boundary-layer moisture create uncertainty around the precise low. Trader sentiment remains balanced between the 22 °C+ and sub-13 °C bins because small shifts in forecast guidance—such as revised humidity profiles or wind speeds—could push the observed minimum across key resolution thresholds before official China Meteorological Administration readings finalize the outcome.
