Strong market consensus on 36°C for Jeddah's September 24 maximum reflects consistent official forecasts from regional models showing clear skies, light northwesterly winds, and peak afternoon readings near 36°C at the King Abdulaziz International Airport station. This aligns with Jeddah's late-September climatology, where Red Sea coastal humidity and typical insolation produce highs averaging 35–37°C without significant cloud cover or stronger sea breezes. Recent observations confirm similar values the prior day, with minimal model spread supporting the outcome. Realistic challenges include localized measurement differences, an unforecasted marine layer, or slight cooling from enhanced onshore flow that could shift the recorded high by 1°C.
