Current forecasts from agencies like the National Center for Meteorology point to a peak near 38–39°C in Jeddah on August 5, driven by seasonal summer heating above long-term averages across Saudi Arabia and the moderating influence of Red Sea sea breezes that typically cap coastal maxima below inland values. High humidity from maritime air masses raises the heat index but has limited effect on dry-bulb readings used for market resolution, while variable wind speeds and potential afternoon cloud buildup could shift the exact high by 1–2°C. Traders weigh model consensus showing limited intensification potential against historical August baselines near 37°C, with any late-day clearing or stronger onshore flow tilting probabilities toward 40°C or higher.
