Forecast models from sources like the Met Office and local stations indicate Jeddah’s overnight minimum on October 7 will likely settle between 28–31 °C, consistent with the closely matched market probabilities. Persistent northwest winds off the Red Sea, combined with high humidity (60–80 %) and limited cloud cover, suppress radiative cooling and keep surface temperatures elevated compared with inland desert sites. Light pressure gradients and the absence of frontal systems maintain this marine moderation, while urban heat-island effects at measurement stations can add 1–2 °C. Historical October lows average near 27 °C, but current warm sea-surface temperatures and stable high pressure support the higher end of the range; updated model runs tonight will refine the precise minimum before resolution.
