Current forecasts from major models indicate a typical late-summer maximum near 37–38 °C for Jeddah on August 25, driven by persistent subtropical high pressure, strong solar heating, and light northerly to westerly winds with moderate humidity from Red Sea moisture. This aligns closely with the August climatological average high of roughly 36–38 °C and recent observational trends showing stable hot, mostly clear conditions with minimal cloud cover or precipitation. Ensemble guidance shows low day-to-day variability, though minor shifts in steering flow or afternoon convection could adjust the peak by 1–2 °C before resolution. Traders monitor updated runs from ECMWF and GFS ahead of the date, as these directly inform implied probabilities around common temperature thresholds.
