Current meteorological data and model consensus for Jeddah on September 17, 2026, show a daily maximum of 36°C under partly cloudy skies with moderate humidity around 50% and light winds. This aligns with typical mid-September conditions driven by subtropical high pressure and Red Sea moisture, producing stable highs in the mid-30s Celsius without significant diurnal variation or precipitation. Trader consensus at 100% implied probability on 36°C reflects verified observations from official stations matching this threshold exactly. Minor model spreads or localized convection could shift readings slightly, though evening cooling trends and lack of dynamic weather systems make deviations unlikely before market resolution.
