Current forecasts from sources like the National Weather Service equivalents and models place Jeddah's August 18 daytime high near 37–39°C under typical summer high-pressure patterns, clear skies, and Red Sea moisture moderating extremes while sustaining heat. This positions 38–39°C outcomes as market leaders, consistent with historical August averages of 37–39°C and recent runs showing limited variability from stable steering winds. The 40°C+ probability reflects occasional model spreads for peak heating if winds weaken, while lower brackets remain discounted absent cooler anomalies. Updated model ensembles and official observations over the next 48 hours will likely refine these trader-implied odds.
