Current forecasts for Jeddah on August 30, 2026, indicate a daily minimum near 31°C amid above-normal summer heat, consistent with the tightly clustered market probabilities around 29–32°C. Jeddah’s Red Sea coastal location sustains high humidity that limits nocturnal radiative cooling, while light to moderate northwest winds promote mixing and prevent sharper drops. Clear skies and stable high pressure support gradual overnight declines from daytime highs near 37–39°C, but model variations in boundary-layer moisture and wind speed create the observed spread between outcomes. Recent August conditions have run 2°C above the 32.8°C climatological mean, sustaining elevated baseline temperatures into the final days of the month with no incoming frontal systems to alter the pattern.
