**Current forecast consensus points to a minimum temperature in Jeddah on September 3, 2026, most likely falling between 28–31°C, driven by the city’s Red Sea coastal location and persistent late-summer atmospheric patterns.** High humidity and moderate northwesterly winds limit nocturnal cooling, keeping overnight lows elevated compared with inland areas. Multiple short-range models and historical climatology (September average minimum near 27–29°C) align on this range, with little indication of unusual cold-air advection or clear-sky radiative cooling that could push readings substantially lower. Recent data show stable conditions with no significant weather systems or model shifts in the past 48 hours that would favor extremes below 25°C or above 32°C. Trader-implied probabilities reflect this narrow band of likely outcomes while assigning meaningful weight to the possibility of modest deviations from the central forecast, consistent with typical ensemble spread in coastal tropical environments. Updated model runs and local observations over the next 48 hours will provide the clearest signals for any adjustments.
