Recent forecasts from sources like AccuWeather and timeanddate project August 24 highs in Jeddah near 37–39°C (98–102°F), aligning with the market's tight clustering around 37–40°C outcomes. Primary uncertainty stems from coastal dynamics: Red Sea sea breezes often moderate peak temperatures through advection of cooler, humid marine air, while variable wind directions and boundary-layer mixing can allow greater daytime heating. Ensemble model spreads reflect differences in handling these local effects versus broader synoptic patterns, such as upper-level ridging that sustains seasonal heat. Historical August averages near 38°C provide context, but day-to-day variability from minor shifts in pressure gradients or cloud cover can easily swing the maximum by 2–3°C. Updated National Center for Meteorology guidance and short-range model runs ahead of the date will likely refine trader consensus on whether conditions trend toward the lower or higher bins.
