Recent forecasts for Jeddah on August 28 indicate daytime maxima likely in the 37–39°C range, aligning with the month’s climatological average high near 38°C and recent observed peaks of 37–39°C under clear to mostly sunny skies. Coastal Red Sea influences, including afternoon sea breezes and moderate humidity of 40–60%, typically cap extreme heating compared to inland areas, while low precipitation chances and stable high pressure support consistent solar insolation. Short-term model variability in wind speed, cloud cover, and boundary-layer moisture creates the narrow spread across temperature bins, with new runs from agencies like the Saudi Meteorological Authority or global ensembles expected to refine the precise peak before resolution.
