**Trader sentiment for the lowest temperature in Jeddah on October 14 centers on 29°C (52% implied probability) as the frontrunner, with 26–28°C clustered near 32% and lower probabilities for extremes.** Official forecasts from sources including the Met Office and multiple numerical models project a minimum of 28–29°C overnight into early morning, driven by Jeddah’s Red Sea coastal setting that limits nocturnal cooling through high humidity (typically 70–80%) and light northerly winds. Clear or mostly clear skies under a stable high-pressure regime allow some radiative heat loss after sunset, but persistent warmth from the sea surface and regional subsidence keep readings from dropping further. Recent model consensus has remained steady, with no significant revisions from upper-level ridging or moisture intrusions that could alter the overnight low. This positions 29°C as the modal outcome matching current guidance, while the secondary cluster around 26–28°C reflects residual uncertainty in exact timing of the daily minimum and minor model spread in boundary-layer mixing. Historical October baselines for Jeddah (average lows near 28–29°C) further anchor expectations absent any anomalous synoptic shift before resolution.
