Recent forecasts for Jeddah on October 1 point to a daily high near 36°C, aligning with the market's leading 47% implied probability for that outcome and supporting the combined 68.5% odds on 35–37°C. Coastal Red Sea humidity and persistent clear skies under typical early-autumn steering patterns sustain elevated temperatures, while climatological data show October averages of 34–35°C with limited day-to-day variability. Short-range model consensus from sources tracking the current heat wave shows minimal cooling through the first of the month, though minor shifts in wind or cloud cover could adjust the final maximum by 1°C. Updated guidance closer to the date will determine whether readings settle at the lower or upper end of the favored range.
