Recent forecasts from agencies including the Met Office and model consensus point to a daily maximum near 36°C in Jeddah on October 4, driven by persistent clear skies, strong solar insolation under a subtropical high-pressure ridge, and light to moderate southwesterly winds that limit cooling from the Red Sea. Historical October averages for the coastal station hover around 34–35°C, with 2026 conditions showing minimal deviation due to stable atmospheric patterns and negligible precipitation risk. Trader emphasis on the 36°C outcome reflects tight clustering in short-range guidance, while the modest probability for 37°C accounts for potential model spread in peak heating under high humidity. Updated runs ahead of the observation window remain the key near-term catalyst.
