Forecast models for Jeddah on October 2 project daytime highs near 34–36°C under mostly clear skies and light westerly winds, aligning with the market’s heavy weighting toward 35–36°C outcomes. Jeddah’s Red Sea coastal setting sustains elevated humidity and limited nocturnal cooling, while early October climatology features gradual seasonal decline from summer peaks yet retains strong solar heating with minimal cloud cover or precipitation. Recent model runs show tight consensus without significant cool-air intrusions or dust events, supporting trader confidence in the narrow 35–36°C range. Final resolution will hinge on official maximum readings, which could shift modestly with any unexpected wind or humidity changes.
