Recent official temperature observations from Jeddah monitoring stations, combined with stable atmospheric conditions including high solar radiation, light winds, and low humidity typical of early September along the Red Sea coast, have driven near-certain trader consensus on a 38°C daily high. This aligns with climatological baselines where September maxima average 35–36°C but can spike under clear skies and subsiding air masses. The implied probability exceeds 99% because live data show readings consistently tracking toward this threshold without divergence in short-range forecasts. Scenarios that could realistically alter resolution include unexpected afternoon cloud buildup reducing insolation, a shift in the sea breeze moderating peak heat, or minor discrepancies in station-specific measurements versus the official reporting methodology used for market settlement.
