Current forecasts for Jinan on September 1, 2026, indicate mostly clear skies and light northeasterly winds under 10 km/h, favoring strong nocturnal radiative cooling after daytime highs near 29–30°C. This setup typically drives minimum temperatures into the mid-to-upper teens Celsius, consistent with early-autumn climatology where average lows hover around 18–20°C. Trader sentiment clusters around 14–19°C because small differences in boundary-layer humidity, exact timing of the overnight low, or minor urban heat-island effects can shift the recorded minimum by several degrees. Model consensus shows limited spread in large-scale advection, leaving local radiative and turbulent processes as the dominant sources of uncertainty for market resolution.
