Official forecasts for Jeddah on August 15 position maximum temperatures near 39–41°C under mostly sunny skies with light winds, driving the 76.5% market-implied probability for 40°C or higher. August climatology along the Red Sea coast features peak seasonal heating from persistent subtropical high pressure, with historical daily highs averaging 38–42°C and frequent exceedances of 40°C amid low rainfall and elevated humidity. Recent model runs show stable consensus without significant cooling from regional winds or cloud cover, though late revisions to observed highs could shift outcomes toward the 39°C or 38°C bins. Traders weigh these typical summer patterns against measurement uncertainty at resolution.
