**Trader sentiment for Jeddah’s September 2 minimum temperature reflects stable late-summer conditions along the Red Sea coast, with models converging on a 30–31 °C low amid light northwest winds and moderate humidity.** Forecasts from multiple sources (including NWP runs and climatological analogs) show daytime highs near 36–37 °C dropping overnight under partly cloudy skies and dew points around 18–22 °C, producing limited radiative cooling. Outcomes clustered at 26–29 °C (50 % implied) would require stronger nocturnal winds or clearer skies than currently projected, while 30–32 °C brackets align more closely with ensemble guidance and historical September minima near 30 °C. The near-even pricing across these bins highlights uncertainty in the precise overnight minimum, which can shift 1–2 °C with small changes in cloud cover or wind speed before resolution. No significant weather systems or model trends have emerged in the past 48 hours to alter this baseline.
