Recent official forecasts for Jeddah on August 21 project a daytime high near 37–38°C under scattered clouds, consistent with the Red Sea's moderating influence on the city's typical August coastal climate. Numerical weather models show limited variability, with highs rarely deviating far from seasonal baselines around 36–39°C amid high humidity and light winds. Trader consensus, reflected in the 38.5% implied probability for exactly 37°C and 26.5% for 38°C, aligns with these near-term model runs and the low likelihood of extreme deviations this close to the date. Updated guidance from agencies like the Met Office reinforces this range, while the modest 14% odds for 39°C or higher account for residual uncertainty in intensification or measurement precision at official stations.
