**Forecast consensus from regional models indicates a minimum temperature in Jeddah on October 8 near 29–31 °C, shaped by typical late-summer coastal conditions over the Red Sea.** Persistent northwesterly winds and high humidity (70–90 % overnight) limit radiative cooling, while clear skies and light winds allow the diurnal range to reach its usual 5–7 °C. Multiple sources project overnight lows of 28–30 °C, with the precise reading sensitive to small variations in cloud cover, boundary-layer mixing, and exact station location. Trader odds cluster around 30 °C because this aligns with both climatological normals and current model runs, yet the tight spread across 25–35 °C outcomes reflects remaining uncertainty in the final observed minimum before resolution. No major synoptic shifts have altered the outlook in the past 48 hours.
