Recent forecast models for Jeddah indicate overnight minimum temperatures near 28–30°C on October 13 under mostly clear skies, with some runs showing potential radiative cooling to 25–26°C before dawn due to light northerly winds and low humidity. Coastal proximity to the Red Sea sustains elevated dew points around 23–25°C, limiting further drops, while historical October averages place typical lows at 24–26°C. Trader sentiment clusters around the 23°C threshold versus 28°C because model ensembles diverge on exact nocturnal cooling rates and any subtle cloud or wind shifts, creating genuine uncertainty near the market's key resolution bands two days before the period closes.
