Recent forecasts for Jeddah place the August 14 maximum near 37–39°C under typical summer subsidence and strong solar heating, with limited Red Sea moisture moderating extremes via sea breezes. Model consensus from sources like BBC and timeanddate.com clusters in this range, while broader August outlooks allow occasional spikes above 40°C when winds weaken. The tight spread among 39–41°C+ outcomes reflects genuine uncertainty in short-term variables such as boundary-layer mixing and diurnal heating rates, which can shift the peak by 1–2°C. No major anomalies have emerged in the past 48 hours to alter baseline climatology. Traders weigh these factors against historical August averages near 38°C as fresh model runs approach.
