Recent official forecasts from sources like the Met Office and numerical models converge on a daytime high of 34–36°C for Jeddah on October 11, driven by persistent sunny conditions, light westerly winds off the Red Sea, and a stable subtropical high-pressure pattern that limits cloud cover and moisture influx. This aligns with climatological norms for mid-October, when average highs decline from summer peaks near 38°C toward 34–35°C amid seasonal cooling. Trader emphasis on 36°C (43% implied) and 35°C (24.5%) reflects this consensus, while the 22% odds on 39°C+ account for occasional model spreads or brief warming spikes under clear skies. Low precipitation risk (<5%) and moderate humidity further support moderate outcomes, with final resolution hinging on the next 48-hour model updates from regional meteorological agencies.
