Forecast consensus for Jeddah on October 15 points to an overnight minimum near 28–29°C, driven by the moderating effect of Red Sea waters averaging 30–31°C this month, elevated humidity levels around 70–80%, and light northerly winds that limit radiative cooling under mostly clear skies. These conditions align closely with climatological baselines for mid-October, where coastal locations rarely drop below 27°C. Model agreement across sources keeps probabilities tightly clustered, though a modest uptick in cloud cover or wind shift could allow brief dips toward 25–26°C. Official station readings from King Abdulaziz International Airport will determine resolution, with final low typically occurring just before dawn.
