Recent forecasts for Jinan on August 30 point to a mild overnight low near 20–22°C under partly cloudy skies and light northeast winds, with radiative cooling limited by residual humidity from earlier showers. Trader sentiment clusters tightly around 18–20°C because numerical models diverge on the exact timing of clearing and minimum dew points, which control how efficiently surface heat escapes after sunset. Clearer conditions could allow temperatures to dip toward 18°C or lower via enhanced longwave radiation loss, while lingering clouds or a warmer boundary layer would hold readings near 20–21°C. Historical August minima in the region average around 22°C, but the current transitional pattern after recent frontal passages introduces measurable uncertainty in the final overnight reading.
