Recent ensemble forecasts from global and regional models point to peak temperatures in Jeddah on August 23 likely falling in the 38–39°C range, driven by persistent subtropical high pressure, clear skies, and light northwesterly winds. The Red Sea’s moderating influence and typical summer humidity levels near 50% help cap extremes below 41°C while preventing dips much below 37°C. Historical August averages hover around 38°C, providing context for the narrow spread in trader-implied odds. No significant weather systems or cloud cover changes are indicated in the latest guidance, though afternoon sea breezes could trim the daily maximum by 1–2°C. Updated National Center for Meteorology runs and high-resolution model outputs over the next 48 hours remain the key variables that could shift consensus toward 38°C or 40°C.
