Recent forecast guidance for Jeddah on August 13 shows maximum temperatures likely reaching the upper 30s to low 40s Celsius, driven by typical peak-summer radiative heating over the Red Sea coastal plain combined with light northwesterly winds that limit cooling. Model consensus places the daily high near 39–41°C, with some runs supporting brief spikes above 41°C under clear skies and low humidity, while others cap values closer to 38–39°C due to slightly stronger sea breezes. These conditions align with August climatology, where historical averages hover around 38°C but daily variability frequently produces readings near or above 40°C. Traders have priced the 41°C-or-higher outcome as the narrow leader at 51.5% implied probability, reflecting the balance between central forecast values and upside potential in the final model updates expected before resolution.
