**Latest forecast models for Jeddah on October 2 point to a daytime high of 33–36°C under predominantly clear skies and light westerly to northwesterly winds, aligning with the tight market split between 35°C and 36°C.** Coastal Red Sea location and typical early-October climatology produce strong diurnal heating that peaks midday, with humidity often exceeding 50% moderating the actual air temperature while elevating heat index values. Stable high-pressure conditions and minimal cloud cover support the upper end of the range, though slight differences in model timing of peak insolation or wind strength can shift the exact maximum by 1°C. Official monitoring from agencies such as the Saudi National Center for Meteorology and global ensembles will provide the definitive reading used for market resolution.
