**Forecast consensus from major models places Jeddah’s July 8 maximum near 37–39 °C, keeping the 38 °C-or-higher bin the market favorite at 54.5 % implied probability.** Jeddah’s Red Sea coastal setting produces persistently high humidity that tempers peak dry-bulb readings relative to inland Saudi stations, while the regional subtropical ridge and northwesterly flow maintain clear skies and minimal cloud cover. Long-term climatology shows early-July daily maxima averaging 37–38 °C, with frequent excursions above 38 °C; current extended-range guidance from AccuWeather, timeanddate, and national meteorological sources aligns with this baseline, projecting 37–39 °C for the 8th under continued stable, dry conditions. No significant synoptic changes—such as a stronger sea-breeze or upper-level trough—are indicated in the next 48 hours, limiting downside risk for temperatures below 37 °C. The modest probability mass on 37 °C (17.5 %) and 36 °C (11.5 %) reflects residual model spread around the precise daily peak and typical forecast uncertainty near the threshold. Upcoming short-range model runs and any last-minute adjustments from the Saudi National Center for Meteorology will be the primary near-term catalysts for shifts in these market-implied odds.
