Recent official forecasts from regional meteorological services indicate peak daytime highs in Jeddah of 36–38°C through August 11, consistent with the market’s clustered probabilities around 38–40°C. Jeddah’s Red Sea coastal position typically moderates extremes via persistent sea breezes and elevated humidity, keeping August maxima near the long-term climatological average of 36–38°C rather than inland peaks. Subtle differences among leading outcomes hinge on short-term model variations in wind speed, cloud cover, and boundary-layer mixing, with global ensembles showing limited spread this close to the date. No significant synoptic shifts or heatwave signals have emerged in the latest runs, leaving trader sentiment balanced among these thresholds pending updated guidance.
