Recent forecasts from sources including the Met Office and BBC indicate peak temperatures in Jeddah on August 5 will likely fall in the mid-to-upper 30s Celsius, consistent with August climatology of roughly 37°C average highs driven by intense solar insolation under subtropical high pressure and Red Sea moisture. Trader consensus clusters tightly around 37–39°C because subtle differences in model guidance on sea-breeze strength, boundary-layer mixing, and any thin high-cloud cover can shift the daily maximum by 1–2°C. National Center of Meteorology outlooks for hotter-than-normal regional conditions support the modest probability of 40°C or higher, while stable steering patterns reduce chances of cooler outcomes. New model runs and observational updates over the next 48 hours will refine these thresholds ahead of market resolution.
