Recent forecasts from major models align on a stable subtropical ridge maintaining clear skies and light northwesterly winds over Jeddah, supporting daily maxima near 37–38°C on August 24 amid typical Red Sea humidity levels around 50–60%. This places the market’s leading 38°C (34%) and 37°C (28.5%) outcomes in close contention, with differentiation hinging on precise timing of peak insolation, minor cloud variations, and local measurement thresholds rather than broader synoptic shifts. Historical August climatology shows averages near 37–39°C, while current guidance indicates little deviation through the weekend, leaving traders sensitive to the next GFS or ECMWF runs for any subtle adjustments in boundary-layer mixing or sea-breeze effects.
