Trader consensus strongly favors an 18°C low in Jinan on September 28, reflecting alignment across official forecasts from the China Meteorological Administration and global models. Current conditions show partly cloudy to overcast skies with light southerly winds and high humidity near 80 percent, limiting radiative cooling overnight. Observed temperatures bottomed near 20–21°C in early hours before stabilizing, consistent with the expected minimum around 19°C under these stable atmospheric patterns. Historical September averages for the region support this range absent major frontal passages. The positioning could shift only if clearer skies develop rapidly, enhancing overnight heat loss, or if local station measurements diverge due to urban heat island effects or microscale variations.
