Current ensemble forecasts from global models for Jeddah on July 1 point to daytime maxima near 37–40°C under typical early-summer conditions, with strong solar insolation, light northwesterly winds, and Red Sea humidity limiting overnight cooling. This aligns with climatological averages of 38–39°C for early July and recent late-June observations that reached 36–40°C without significant cooling trends. The market’s emphasis on 38–39°C or higher reflects these stable patterns, though modest model spread and any late adjustments in steering flow or moisture could shift the peak by 1–2°C before resolution.
