**Trader consensus at 100% implied probability for 35°C as Jeddah's daily maximum on October 13 reflects consistent official forecasts from sources such as the Met Office and regional models projecting a peak of exactly that value.** Clear skies, light to moderate westerly winds, and typical mid-October Red Sea coastal conditions support gradual daytime heating to this level without significant moisture or cloud interference that would suppress temperatures. Historical climatology for Jeddah in mid-October shows average highs near 34–36°C, aligning with the current setup. Late-day observational revisions or localized microclimate effects could theoretically shift the recorded high, though current stability in atmospheric patterns makes such outcomes improbable before resolution.
