Jeddah's July climatology, with average daily highs near 37°C driven by persistent subtropical high pressure and strong radiative heating over the Red Sea, underpins the market's concentration of implied probability on 36–38°C outcomes for July 14. Recent numerical weather prediction runs show stable northwesterly flow and minimal cloud cover through mid-month, keeping temperatures aligned with seasonal norms rather than anomalous heat or cooling from transient moisture surges. Short-range ensemble guidance indicates modest day-to-day variability tied to boundary-layer mixing and sea-breeze effects, with the highest daily maximum likely falling between 36–38°C absent unexpected synoptic shifts. Updated model cycles and official Saudi meteorological briefings over the next 48 hours represent the key data points that could refine these probabilities before resolution.
