**Forecast consensus places Jeddah’s October 1 minimum near 28–29 °C under stable high-pressure conditions and light southwesterly flow off the Red Sea.** Multiple models, including Met Office and regional guidance, project overnight lows of 28–29 °C with daytime peaks around 34–36 °C and minimal cloud cover, consistent with late-September observations of 28–29 °C minima. The near-even split between 29 °C (50.5 %) and 24 °C or below (49.5 %), alongside 28 °C (48.5 %), reflects uncertainty in the precise hourly low: coastal humidity, slight wind shifts, and station-specific measurement timing can shift the recorded minimum by 1 °C. No significant synoptic changes or model divergence are expected before resolution, keeping trader focus on these narrow thresholds.
