Latest forecast models from agencies including the Met Office project a daily minimum near 28°C for Jeddah on October 9, driven by persistent clear skies, light northerly winds, and Red Sea moderation that limits nighttime radiative cooling in this coastal setting. High humidity levels around 70-90% overnight further suppress temperature drops, while stable high pressure maintains typical early-October conditions without significant cold-air advection. These factors explain the tight market balance near 50% for 24°C or below versus 34°C or higher, with genuine uncertainty in exact minimums due to microscale coastal effects and model variability. Updated runs from numerical weather prediction centers will refine resolution criteria ahead of the date.
